Choosing parts for a mill conversion

[thommy]

I have an old Hobbymat BFE65 East German vertical milling machine which I plan to convert.



CNC is new to me but I have a background in both engineering and electronics, software will be EMC2 on Linux probably. I hope to do all 3 axes directly driven with stepper motors, but not too sure about motor choice for the Z as the milling head weights 20kg.

Here's my shopping list so far:

3x Nema23 3.1Nm motors
3x DM542A stepper drivers
36v 350w SMPS
USB breakout board

I will need some motor mounts and couplings, but what about the rest of it?


Thanks

Having looked further into this idea, it seems that actually what I need is a 300 x 200 router instead so will not be going ahead with this conversion.

Are you keeping the machine? I believe manofgresley has one of those and may be looking for parts/spares/upgrades/etc...
