Nema17 motors driving 1204 ballscrews ...that ok?

[HankMcSpank]

Thanks guys

Hank 1204 will be fine but you will need to mod the Z plate to take the Ballnut by the looks of it?

I haven't taken the Z backplate off to have a look, but I think the X axis ought to take a 1204 ballnut (which according to the spec sheet - http://images.tiu.ru/22699355_w640_h640_sfu1605.png ...top entry, not the highlighted entry in that table!), should fit...



Can anyone tell me the difference between a 1204-3 & a 1204-4? (& no smart replies saying 1 please!)

I think I'm gonna stay with this machine a little while longer, cos yesterday I found & ordered a dedicated spindle which looks like it suits my needs (& until yesterday I didn't even know existed)....




a video of it in action (spindle porn!)...



the spiindle, motor & mounting plates (everything in the picture) only totals £66 plus £15 delivery - which to me seems very keenly price (nice & quiet too...and 10,000RPM ought to be enough - my present spindle only goes up to 5,000rpm)...so I pulled the trigger & should have it in about 10 days.
