This is a modification of the original Zaribo Y-Axis (https://github.com/Zaribo/Zaribo-MK3) to replace the Misumi bearings by linear rails of 15x15 size. I have used the next rails and blocks:
- 2 x HGH15CA blocks
2 x HGR15RH rails (length must be 354mm)
I have used only two blocks instead three because they are too big and they don't fit on the left rail, a special adaptor has been designed.
The Motor Holder an Y-Tensioner must be changed by the ones I have included here because the carriage is 10mm higher, so I have increased the heigth of these pieces by 10mm.
WARNING: The use of this modification implies loosing 10mm height, because the size of the blocks. So the firmware must be modified by 10mm less (310mm for a Zaribo 320) for Z calibration to work.
The file Zaribo_MK3_310.h to compile the firmware and the firmware FW370-Build2211-Zaribo_MK3_310-EN_ONLY.hex are included for a Zaribo 320.
I have included the step files for your own modifications.
- Eight M4x8 screws
- Two M3x12 screws
- Four M3x16 screws
- Two M6x12 screws
- One M6x20 screw
Added a new adapted Y-Tensioner modified from the one released by Vekoj (https://www.thingiverse.com/thing:3595521)
Minor fix: corrected the distance between holes to attach the heatbed, it was 21mm and must be 20mm
