I had quite a struggle getting them to run due to a) pretty crappy chinese documentation and b) I missed the fact that each motor had it's own enable line that must be held high during operation.
But they seem to be working fine and are actually a lot less noisy than I expected them to be.
Hopefully they'll have enough juice to drive my rig...

nice. they nema23's? whats the amp draw on those babies? I have a bunch of nema17's for my reprap I'm building.
ReplyDeletewhat spindle are you going to use for your router?
Hehe, good eyes! ;)
ReplyDeleteYepp - they're Nema23's. They are rated at 3A each and hopefully have enough torque to drive my rig. Actually, I couldn't prevent them from spinning by holding the axel manually so I'm not awfully worried about that. :P
57BYGH633 is the model number.
I will be using a multitool for the prototype version, which should suffice as a proof of concept. I've seen a large amount of smaller CNC's on youtube using dremels/multitools etc with pretty decent results. But eventually I'll replace it with something similar to this one ( http://preview.tinyurl.com/bv74csu ).
Still haven't gotten my hands around actually building it yet, still working on the plans (constantly redesigning!) and still haven't purchased the remaining hardware (wood/MDF's, screws etc). But soon! :)
