Rebuild, Continues Part 3

Final Assembly, Boot, Config and Print

Lab Work – Rebuild Part 3

I encountered a bit of a snag, but I am rebuilding and continuing with part 3 – working through those challenges now. For the time being, please refer to the updates above/below for part 3 updates. We will be covering more of the rebuild process, including the x/y axis bands, plate, direct drive issues, boot/reboot procedures, and reinstalling printer drivers. Additionally, we will discuss slicers, nozzles, extruder/heating element, and the latest issue, the onboard/external interface.

Breaking Through, Troubleshooting activities

As noted in the previous build, Part 2, we are likely around 80%-90% complete at this point. We will refer to this rebuild as Part 3. We have encounteered some filament burn and melt down, as well as blockers that we will address in Part 4. Nonetheless, Part 2 was successful, and now Part 3 is also going well, with all parts functioning as expected and the boards booting as they should. The new drive and extruder are working in tandem as intended. The ‘issue, as previously mentioned, lies between the Creality Sonic Pad, printer board and connecting software. Images will be included to illustrate the challenges faced during the rebuild, including manual updates made on the printer screen, main board, and the area where we are currently stuck with the Sonic Pad. Two notable errors are the Klippy software and Sonic Pad physical connection failure, as well was filament recognition.

Out next steps will involve installing/rebuilding Klippy, testing, retesting print config files, reattaching the Sonic Pad, replacing extruder tubes, nozzles, adjusting e-Steps, home position and more, while also adding the Wifi Box 2.0. Once all of these tasks are completed and throughly vetted and tested, we will create a brief update of the build and active prints to mark these items of the rebuild list.

Got to love technology (or not), and office ‘helpers’ Zeus thought he would take a little snooze while the troubleshooting session continued throughout the day and night. The same can be said for discovery and testing, there’s no time like the present. Some folks call it the ‘grind’… I’ll leave that there for you to imagine. Is it painstakingly difficult? No. Time always plays a role, especially when speed-to-market is crucial. You have to be willing to work with what you have… Part 4 will be coming shortly, where we will cover fine tuning, steps, extrusion, adhesion and whatever else pops up in the meantime.

WiFi For Legacy Creality Devices

Bring Bluetooth and Wifi Connectivity to Legacy 3d Printers

Creality WiFi Box

Tech | Tools – Creality WiFi Box 2

Need a boost, WiFi or Bluetooth connection for your Creality printer? How about the Creality WiFi Cloud Box 2.0?

For those of you who are using using WiFi or Bluetooth connectivity, especially the older 3D printers, the concept of ‘Apple AirPrint’ or printing over WiFi is now a luxury. Unless, of course, you want to take advantage of Air Print or prefer to print from your desk chair by connecting to a WiFi/Bluetooth ready 3d printer. It’s simple if the hardware and software are installed or onboard, as is often the case. You can easily sit down, go through your sketch or drawing export, and then send those slices directly to a printer via WiFi/Bluetooth. Finally, you can kick off the print job using WiFi/Bluetooth slicer software.

Creality Wifi Box

Before I discuss the best-case scenario and the benefits of WiFi for legacy Creality devices, let’s first talk about the old-school models. For those of us who still use old printers, MicroSD cards, USB 2 cords, and swap nano SD cards and USB sticks, this information will be relevant. If you’re tired of constantly switching USB dongles and nano cards and dealing with manual process, then this if for you. It may be old school, but it work.

Please note that I have not yet set up the Creality WiFi Box so there is no Wifi available for the legacy Creality devices I own. We will get something up here shortly, once the rebuild is complete which should take about a week or two to wrap up.

Rebuild pt 1 – involves installing a new drive, assembling, and finding the back plate. Currently, we are reconnecting the new assembly housing, heating element, etc. rebuild part 2* did start the today this article was posted. *Article was updated, so that we could share a link to the second article.

Finally, we will cover Creality solutions for older 3D printers such as the Creality Ender 3 Neo Max.

Filament Spool Update

Filament Rack, Digital Scale, and Spool

Creality Digital Spool Rack

Gear – Filament Rack

Needed an additional part/piece, this Creality Spool Rack.

Today, we have a Filament Spool Update and the final accessory to add to the TPU upgrade build. Dare I call it the final piece of the puzzle for the build.

What are we looking at here? It’s a top-mounted (overhead) rack, specifically the Creality Digital Spool Rack. The rack, or filament management rack sits atop the main brace/cross-bracket framing structure as shown below (see new spool image). The spool rack will allow for multiple filament types:* PLA, ABS, Nylon, Wood, and TPU *assuming the filament comes on a spool, regardless of the size. It’s important to note that Creality includes a portion of filament or test filament with a new or refurbished printer. This information is helpful for new 3D printer users.

The advantage? TPU specifically can unwind and pass through a top cross-brace funneling mechanism directly into the new direct drive extruder. This serves as the new static filament storage area/piece. For those of you with a Bowden drive, you may not understand, but after the upgrade, we needed a way to feed filament to the direct drive extruder. This serves as the solution.

3D Printer Accessories

New Spool

Digi Spool

Spool Rack

Creality makes this handy filament rack, replacing the OEM side mounted rack. It’s perfect for filament management – size, weight over time etc. Same as the OEM rack with a few upgrades like a bright, digital scale. The rack has a large, bright digital scale Interface, a great visual for filament volume, space and duration.

The key here, as part of the Filament Spool Update, the digital read out (interface) built into the spool mount brings ‘site by volume’. And as you can imagine, this can help predict usage, and consumption rates. More importantly, cost per item or printable. It’s small enough to screw to the topside of the support frame. The interface is bright enough to work in the dark, cast enough light onto the printer bed. Note, all filament types in spool formant should work on the rack, TPU, ABS, Nylon, Wood and/or PLA. All material come into scope once the direct drive is up and functioning as expected.

Gadget Backlog Update

Let’s Look At the Gadget List

Klein Screwdriver Set, SHURE MV7 Podcasting Kit, and Aupus Air Duster

Gear – Backlog

Quick update on the Gadget Backlog, SHURE MV7 Microphone Podcast Kit, Air Tools – Inflators, Nailers Gauges and Compressors (out soon), Air Duster (A.K.A Air “Cannon”) and Klein Tools Precision Screwdriver Set.

Both positive and negatives, the Klein set is a big win, those of you needing a sleek, high-quality, tech/electronics platform; Klein is the way to go. Same for the Aupus Air Duster… a handy, handheld, to blast away dust and debris… And the SHURE MV7, same on quality, and crisp sound quality, the best with SHURE.

Let’s start with the ‘good’ vs the ‘bad’ or ‘ugly’ movie reference “The Good, The Bad, The Ugly – Clint Eastwood”. Let’s cover the precision screwdriver set and air duster.

Klein Tools Precision Screwdriver Set

First, the Klein All-In-One Precision Screwdriver Set. If you’re working with smaller appliances – coffee/espresso machines, vacuums, toys, gaming equipment, computers, phones or tablets (Apple specifically). You’re gonna need an elevated, array of tech gear and tools such as – glues, adhesives, adhesive ‘strippers’, grounding elements or bands, gloves, fans, shims or prying tools, same for hex/Torx bit heads… Just to name a few.

In many cases, if one was to change out a generic computer battery (Apple MBP) you might need – micro Phillips-head/Torx, pry tool, shims, glue stripper, gloves, heating elements, grounding band, adhesives and then the micro Philips-head and Torx to secure the updated battery array and shell Hopefully you can understand here, the Klein All-In-One covers the range of electronic screws and bolts used in the latest gear.

Just want to spend a few mins on the screwdriver set which comes in a sturdy, rugged, hard plastic box (tough box)… with what Klein calls a stay-shut latching mechanism, again, handy to have when your carrying mini-bits/drivers around. The case is great for indoor/outdoor, ‘shop-like conditions’ which may not be pristine per say. Contained within the tough outer shell, a magnetic hand screwdriver base or platform for ‘finger tightening/loosing’, a preformed bit section for 39 extra-long driver set which includes – flatheads, hex, Torx, square, star and Phillips-head bits.

Those of you needing Apple specific driver bits, check out this set and pick yourself up a set(not a paid advertisement). High quality stuff, easy to use and magnetic. Always nice and handy to have magnetic tools for very small applications, those of you who require small tools for small screws, clips and bolts. Great set for those who need one, pick one up a Klein Tools.

Aupus Air Cannon

Moving along now, staying with the ‘Good’. No cans, no more air canisters, missing straws, cold hands and/or the storage space for air cans. Nope, the Aupus Air Duster is a win for two reasons, space and strength. No need to save space for 5 or more cans of compressed air. We are talking desktop or storage space for those of you working in tight office spaces; the DIY(do-it-yourself).

The Aupus purchased has two settings of air pressure or strength, both will help push dust and debris out and away from it’s intended target. Sound is constant, no shuddering or sputtering, no power loss or surging. The air duster is made of rigid plastics, great for many applications around the shop – featuring a friendly grip, multi-speed selector, filtered intake and a set of cleaning tools – brushes, extension tube, additional filters and fine funnels for more precise air distribution. No batteries, just an old-fashioned plug and play, so, plenty of power where and when you need it when comparing the Aupus Air Duster to a generic can of air.

The SHURE Podcast Kit

Let’s transition to the ‘bad’ or mixed review now. The ‘bad’, might be a little harsh.. When sticking to the theme of “The Good, The Bad and The Ugly” perhaps the final product covers the bad and ugly. For the sake of the argument, let’s just use a ‘soft pass’ on the Shure MV7. Specifically due to it’s reliance on additional software. That’s the rub for this article. Which is where we feel it fails to meet expectations, so, a mixed review of sorts.

The positives, sure SHURE (SHURE MV7 – Podcast Kit) makes a great product, excellent sound quality, nicely packaged for various applications – live-streaming, home recording, podcasting and more. Hardware is what you would expect from the legendary Chicago, IL – Sidney SHURE founded audio/electronics and hardware manufacturer, for nearly 100+ years, producing some of the highest quality audio (electronic gear/hardware)… it’s tough to give this one a mixed review.

MOTIV Required

Honestly, I think this is why we might merge the ‘ugly’ with the ‘bad’. What ‘smokes out the deal’ for us, is the reliance on a secondary application called MOTIV. I get it, the software a need, a must. How else would you use the microphone? The software helps the user fine tune the collection of sound, amplification, distance of sound travel, and hardware recognition. Again, the rub, it’s yet another app/window chewing up space, floating desktop application cluttering up an already densely populated screen – browsers, live-streaming apps, video software, editing software and so on.

You get the picture, an ugly one. Although, you may not agree, that’s fine… this is where I think the experience falls short. If there ever was a time where hardware shouldn’t require os manipulation or software. This is the time, we would have a winner. Again, great kit, includes all the connections one would expect these days, USB-C, XLR, a desktop mount for local sound collection, and crisp sound recording.

The product was built and sold as a podcasting kit, targeting those v-loggers podcasters and content creators. Or, the interwebs adventurers, the law tubers, the gamers, the influencer type and/or home/office applications. All is well, until you understand, an application is required to download and run the physical hardware. The MOTIV app can be downloaded here, found on either App Store or Google Play Store. Caveat, multiple OS platforms, MacOS, Windows and Ubuntu. Honestly, this is not the solution for me. I was open to new gear and not said proprietary software running to manage external hardware.

Takeaway

Final thoughts, takeaway, give it a shot, the microphone is fantastic, sound quality is top notch. A home-run, if I might use a sports analogy as well. If you’re looking for a reliable microphone, precision sound quality (bar-none), this might just be your winning ticket. For us, however, we will pass for now.

Gadget Backlog

Gadget Backlog Includes Items Shipping Soon

Magnet Switches, Extra (Shop) Batteries, Bodum Whisk, SHURE MV7 Mic, Aupus Air Duster, Klein Tools Precision Screwdriver Set, and Med. D’Addario Celluloid Guitar Picks.

Gear – More Gear On The Chopping Block

What’s that in the box, ((shake)) ((shake)) what might that be? A new shipment, what is in ‘the box’ and on the bench.

Let’s start by sharing this on the big Gadget Backlog, is currently in progress, as space is somewhat limited at the moment. More information on that will be coming soon. As for batteries, I have a few Optima Red Tops ready to go, along with some outback welding where necessary. It’s fitting to mention magnetic tools and switches in this context. Yes, super strong magnets that can be switched on and off with a swift turn of the hand or a switch-type mechanism. This is a very cool item to have around the house, shop, or off-road adventures.

Angle Clamps, Mag switches and More Welding Tools

I’m curious to know if the welding community has a preference for welding square/angle holders, clamps, plunger/light switch types, magnetic holders etc., perhaps at no cost. Obviously, if you’re out on the trail, off-roading, doing trail break-fixes, integrity and rigidity might take precedence over OEM specs on angles or manufacturer measurements. When it’s time to getting your off-road rig off the trail, would something like this help to bring your efforts in line with those manufacture specs per say. Anyhow, these switch magnets might be handy to have around the shop. Various types – Angle Clamps, Magswitch Clamp, Stackable Magnets or Adjustable Angle Magnetic Welding Squares.

So, let’s discuss cover what has been unboxed… the Bloom Frother. As you know, the hand mixer needed some adjustments. A few screws, new batteries, some isopropyl alcohol… and we are back in action. You all know I’m a big coffee and tea enthusiast, but if not, that’s okay too. I like my coffee and tea with a few pinches of Sugar in the Raw, and depending on the time of day, I may add some half-and-half to adjust the temperature.

There are a few handheld frothers out there in various color and materials… the Bloom is now revived, with new batteries and ready to mix. So, I am please with the purchase for now. I will provide an update on the long-term usage of the Bloom fix. I must admin, an alternative option might be the Bodum Schimuna Whisk, which has a piqued my interest. For those of you in the market for a micro whisk/frother, the Bodum Schimuna might make a great client gift at some point.

SHURE and Aupus

Next on the Gadget Backlog, we have the SHURE MV7 USB mic! Initial thoughts – great sound, crisp dynamic tones and easy to use. Another step forward towards audio/video experiences. The microphone includes a desktop friendly microphone stand. MacOS users will need to download the SHURE Application to mix and control the external accessory. There is a bit more work involved in getting around the need to purchase additional cables, XLR adapters or fittings. Look for a deep dive, and pictures to accompany the post.

Moving on, let’s talk about ditching the air duster can for a powerful, corded air duster like the Aupus APAD15BL Air Duster. Air cans have served their purpose for many years, especially when paired with electrical-friendly wipes. While we are on the topic of air gadgets, we have more air tools coming your way – Inflators, Air Compressors, Nailers and more. The air compressor even comes with a hand air blower tool for outdoor jobs. Like the air blower, this plug-and-play air cannon offers variable speeds, cleaning tools, and filters. This small, office-friendly tool is handy to have in and around the shop as well. While we are discussing gadgets and tools for the shop/office, we are enhancing the Makey tech tool set by adding a set of Torx screwdrivers (T3 – T10) – Tekprem Torx Screwdrivers.

One downfall I’d like to mention is the integrity of the star and Torx bits. Torx and star bits are delicate and can easily get damaged. A word of caution you have to be careful with nano screws and give it time. Consider replacing the bits or the entire set with a set like these. What I’m observing is that screw lock… can be more beneficial here, but it does take a toll on the micro-bits used to drive in our unwind electronic screws. I’ll provide more feedback and comments on the Torx set and air cannon as we use those items on the bench.

D’Addario celluloid

Finally, last on our big Gadget Backlog list, we picked up a new guitar pick. Most are similar, with smooth or textured surfaces. The main problem I’m having is grip. After a few minutes, grip becomes an issue… it might be the ‘player’, but slippage is a problem. Sweat seems to be the culprit. Odd, huh? So, I’ve added a mixed bag of D’Addario Celluloid picks to the mix. The goal was to switch it up a bit and try something new. I still have a few Fender Celluloid Medium picks and Dunlop Max-Grip variety.

Quick Fix – Nano Mixer

Nano Mixer Fix

Bloom’n Again, Mixer Back In Action

Tech | Tools – Frother Quick Fix

Quick Fix – Disassemble, Clean, New Batteries…

Quickly stir in sugar and milk, mix up your protein powders and fine particulates; all made easy with the Bloom mixer. I wanted to share a quick fix, as our nano mixer quit on us a few weeks back. Typically, the morning and afternoon espresso is ‘cut’ with a few granules of sugar and some half and half… as I get older, the trend has been ‘lighter and sweeter’… any how, here is the internal works of the mixer, teardown – a few screws, clean up, reset the metal prongs and a new set of batteries and we were back in business. Mixing up protein powder, scrambling eggs and espresso/coffee.

Just a note, be sure to keep the lower body (green structural plastic in the picture) dry if you can, there is a bit of a seal there… but better safe than dropping $20 – $40 on a new one. Again, here is the link for the Bloom variety, I think the mixer has been updated since the date of purchase.

We’ve tried the ‘mini blenders’ like the Bullet’s, and the hand blenders, the top of the line so to speak, with the blenders… there are advantages to all, negatives as well. The Bloom mixer is great, now that we got a Quick Fix – Nano Mixer running again. Nice mixer for the small stuff, no need to plug anything in, or clean up pre-made cups etc. Magic Bullet style mixers were great for ‘bullet coffee’*.

Make Bullet Coffee

Never heard of bullet coffee. Make some coffee in a Bodum or Colleti.. or choose your home Coffee Machine. See below. There are a few of the nano/hand mixers on the market, and Amazon can help you find one that fits your budget. I’ve included some below so you can make your own ‘bullet coffee’, with links included…

*Bullet Coffee Recipe: Full Fat Butter, Raw Coconut Oil, espresso/coffee of choice – Nespresso Pods – Tokyo Vivalto Lungo, a few spins of the mixer, and you’re done.

In conclusion, I’ll probably post more about espresso machines, specifically the Nespresso machine. Stay tuned for more. Thanks!

Telescoping Magnetic Picker

Magnetic Tools – Enbar. Need A Hand?

Pick Up Metal Tools, Scrap, Nails and More

Tech | Tools – Working With Metal? How About Small Screws And Bolts? Need A Hand?

Need a hand? Pick up a Enbar magnetic telescoping ‘pick me up’ tool.

This particular Enbar tool has a small magnet that extends from 7″ to 30″, making it handy to have around when you need a magnetic hand. While working on the Jeep, from time to time, a screw or bolt might find it’s way in an area where my fingers and arms simply can’t reach. Additionally, my fingers lack the magnetism needed to pick up 1″ to 2.5″ bolts tucked down in front framing tubes. (I recently ‘lost’ a bold down in the front tubing area, when changing out the headlamps and ended up recovering a star screw multiple times; it just wasn’t a good day to tinker on the Jeep.) This is where the Enbar tool comes in handy.

I chose Mini without a light, the small No.1 Magnet Tool. There are three others in the handheld tool lineup. Some are different in size, while others have a small light to help in tight, dark areas. Check out the Enbar tool if you’re looking for similar assistance in and around the shop or garage.

A handy tool for around $10*, depending on which model you choose. So, for as little as $10 bucks* for the smaller model without a mini light or ~$12* for the largest tool with a light, the Enbar Magnet tool just might be the tool to have around the house, shop or the garage. Maybe get couple – one small, one large? You pick, you pick the right ‘pick me up’ tool for your needs. Don’t forget to leave a comment or share your experience online if you choose to purchase one of these tools. It helps drive that customer review rating (4.6 stars out of 3,925 ratings as of 8/6/2023).

Need A Charge?

In A Pinch – Grab a 9v, a Car charger, electrical tape and a nail

Lab Work – 9v Charger Hack

Before you start criticizing me me about wattages, amperage, safety, or reality etc., I want to clarify that I meant to post this back in December, but didn’t get around to it until now. The scenario is familiar – no power due to a storm outage or a dead car battery, and you find yourself in a bind .You phone is dead, and you need a charge. This hack can be a lifesaver when you’re away from home comforts whether you’re camping, off-grid, or stranded due to breakdown.

I usually avoid cellphone hacks, but this one caught my attention as we enter hurricane season. Having experienced storms, tornadoes, hurricanes, and the like, I know that sometimes the simplest things can make a big difference in a power outage. I’m not suggesting you hoard batteries, clicky-pens, nails, and used charger cords, but it might be wise to have a few on hand, just in case.

This hack has been around for sometime. Some people believe that off-grid living and underground living may require alternative power sources, and this hack could be just what you need. In any case, we spliced together a few generic charging cords, added a car charger, and a few 9v batteries, and voila! We have some juice for the cellphone battery. This hack might work even better. This hack might work even better if you can find a different type of battery, such as an RC/Drone battery considering 9v, LiCB or 4s/5s LiPos. Whatever the case, you may have these items lying around your home, office, or shop, depending on your situation. We have these items in our workshop, so you can imagine how handy they might be in serious storm or power outage situation.

Like the quick fix format? Check out other quick fix content here such as this disposal problems fix. Like the learn to descale your coffee equipment – pots and machines, fix a toilet float clean and fix a pool filter housing and filter which is like this cell phone charging hack… Check them out!
