Updated the Electronics page with a few more selections,
Also added a chart of the motors from keling to quickly see what their amps and voltages are.

Didn't add the itty bitty ones or the monsters, just ones useful for the g0704.

Nice. That makes the choices pretty clear and beats trying to dig it out of his site. He has good products but man is that site unpleasant. Those 570's are really one of the best match-ups for any of the reasonable cost drivers. Pretty clear why you picked them.

Just as an FYI for others. I for some reason thought that the 305/425's from HobbyCNC were the same as the 425's from Keling. Wrong! The HobbyCNC is a 4.0A 60V motor vs the Keling that is 3A 80V motor. I can get my new P/S to put out 55V without much problem but 60V is pushing it up towards it's maximum adjustment and that is still not enough to properly juice the Keling 425's. I have noticed that the HobbyCNC motors don't seem to go quite as fast as other motors. I noticed way back when trying to build my own microcontroller/driver for it. It would not get to the same RPM as some of the other similar motors. They do have a lot of grunt at low speed though.

I did find there were a few other suppliers of the 570's out there since they are not listed as in-stock on Keling, but they were getting rather expensive. If he still doesn't have 570's in stock when I go to setup the Z axis I may step up to a NEMA34 in the 640oz range.

I emailed Keling and they do have 570's in stock. For some reason they don't have them in stock on the webpage but their eBay shop shows them.

I'll soon order 3 pieces for my project. The 570oz model seems to be a good compromize and keeps all XYZ steppers the same size.

Guess I should have emailed then. Dang it.

Homeshopcnc is one that carries pretty much the same 570 stepper but for $73.
Only $8 more.
If kelings been out of stock, this is where I've gone next.

Hmm... I hadn't noticed that 1200 Ouncer before. That may work better for my Z. Quite a bit more expensive though.
