Direct driven ball screw Z-axis for the Indymill
Parts:
Print all the parts which start with "Print..". Print them heavy.
Machine all "..plate" parts. They are supposed to be milled from 10mm aluminum (or 10 mm plywood for testing)
A ball screw SFU1204 with BK10/BF10 (length: 250 mm):https://de.aliexpress.com/item/4001123004767.html?spm=a2g0s.9042311.0.0.7c7b4c4dTJ4nOR
2x 278.5 mm extruded aluminum profile 20x20. I used B-type with 6 mm nut:https://www.motedis.com/shop/Aluprofile/Aluprofil-20x20-B-Typ-Nut-6::1.html
10 M4 hammer nuts for the profiles.
Screws:
16 M3x10
16 M3x14
6 M4x12
10 M4x16
4 M5x16
8 M5x20
10 M6x20
2 M6x35
4 M6x40
4 M5 lock nuts for the motor
The rest can be salvaged from the original build.
The spindle plate has bore holes for the 1.5kW spindle. I will update a file with a hole pattern for the 500W spindle the next days (or if someone has the spindle and can estimate the best bore hole positions please contact me)
Edit: I added a step file with all machined parts.
