ACRO Adjustable Z-Axis
The parts you have for your ACRO X-Axis assembly will be used for this design. You will need in addition:
2 pack 8mm x 150mm
4 LMU8 bearings
8 zip ties that are 3mm wide by 1.5m tall (this will be tight, by design)
M3x100mm Fine adjustment screw, fully threaded
M3 Knurled nut (the idea is that the screw can pass through the nut)
I'll point out that the DXF I used for the laser mount plate was incorrect in the position of the laser screw holes. It didn't affect me - other than I could only use three M3 mounting screws. I've included the Fusion files in case you want to make some modifications. Or start off with a better DXF.
