Assembly & Direct Drive Rebuild, 2
Labwork – Rebuild Part 2
A few steps forward now, we pick up with the bold on extruder assembly and assembly backplate here in part 2.
As noted in the previous build article, part 1, we pick up with the orginal backplate, reusing the backplate while adding in the new assembly hardware. Unfortunately, the new OEM plate was incompatible with the setup I have, so, we’ll harvest the new wheels, screws/tightening washers, bolts and spacers where I can. A quick fit, a dryfit of all the screws, spacers and wheels, placement of the bracket, probe (black, narrow plastic with probe), side fans (yellow and blue wires) and heating element (heater, heat sink and extruder).
The final fit, be sure to tighten down the wheel screws, fan, drive belts and extruder prior to placing the heating element. Order will matter here, same with the removal of the Bowden drive, brackets and extruder tube. We will harvest some of the old tube to help direct TPU filament into the new direct drive extruder. Finally, we place the extruder fan (red and black wires). At this point, you can unscrew the two top wheels in order to place the new direct drive platform, tighten down and snap in the carriage case (caution hot should be on top).
Next, the direct drive, clip on the tube provided, snip tube after a fitting or two. Do make sure, the fit is proper. The direct drive platform is screwed in from the backside of the plate, installed on the last step. Following a screw down action, you’ll need to connect the direct drive motor to the main ‘line’ by passing the frame platform where the old extruder motor lived (see last couple of images) and place the harvested tube for filament.
Easy right? Part 3 coming shortly, we will cover that tomorrow, we’ve got to replace the heating plate, power on the machine and change the step movement.
