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.

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.

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.
