I would say for 1.5k it is possible to convert it with the right choice of components.

80-90vdc or 60-70vac toroidal power. Drivers that can take 80vac/110vdc like:
DM860T drivers https://www.omc-stepperonline.com/di...or-dm860t.html
and these: X, Y

from stepperonline.

Combination of high voltage and lowish inductance will give good performance.
For ballscrews it gets trickier. If you can fit them in you want DFU2005 double nut all round (or DFU1605 on x, y if too tight a fit).
Now, some out there are total crap so watch out.
Good ones still likely need tweaking on the pre load.

Make your own bearing mounts, nut mounts, motor mounts and fit with AC bearings. Material cost is the main dilemma here.
For bearings I use Dunlop AC on my 25 mill, price is good afaic.

For controller I think a UC400eth, UCSB type breakout board, UCCNC software, and a cheap laptop from ebay, would be the best value.
I'll look at breakout boards later.


I converted manual first for x, y. Then used x, y to make z.
Then re-did x, y.
Is there a make for the ball screws and nuts you would recommend as suitable ?
