Hey Mike,
your photo shows very well how close the center of the milling motor is to the Z rails on the Onefinity CNC with the original 65 mm mount. The milling motor sits nearly “between” the Z rails.
There have been many discussions in this forum(1) about universal spindle mounts or replacement Z sliders, but they all had to admit that with mounting another motor mount or even another Z axis assembly, the center of milling motor would move away from Z and X rails and therefore would increase the leverage force that the milling motor weight and work load would exert on them - with doubts of many on how the Onefinity CNC would deal with it then.
1.)
- Universal Z Axis Assembly - Feature Requests
- Has anyone replaced their Z axis assembly for greater travel?
- Any hobbyist grade solutions for adding automatic tool changes to onefinity?
I find your photos, measurements and drawing very helpful, thanks!
