Wiith the 54v and if the motors are 3000RPM@150V (I think thats what they were) then you will get just over 1000RPM, 1:1 gearing with 0.200 ballscrew will give you about 200IPM. If you can live with that then yes it should be ok. Another thing to bear in mind is whether the transformer youhave is suitably rated for the current you will draw.


I dont think I would risk going over the 80V, I think I have seen some guys go as high as 90V with the stepper drives from Gecko but  I wouldnt expect to get any replacements from Geckodrive if they go pop :D

Hood, thanks for all the input. No, i wouldn't go over 80v. I'll hook up the 54, and run a servo and see what kind of draw I get. I hooked up a small battery charger to The y axis and on 6v it ran about 10" i pm.
Thanks again, and I'm sure this won't be my last time on here.

Hood, I got my 340 greckos and my pmdx board. I also ordered a mod io from  Homman , as I want to install some manual switchs.
 My question is, is there any way on Mach,when running a program , to do a tool check,or z home, and return to the last line in a program ?
I can do that on my other mill,but don't see how to do it on Mach.
 Thanks

Not sure what you are really meaning, but for example if you do a feedhold you can jog anywhere you want  and the when you press start it will move back to the last line and continue.

Dave are you using that with the Mach Plugin or are you using their control software?
