Nothing beats a Geck drive. My THB6064AH driver is nearly as good, and about half the cost. See the link in my signature.

Still overkill for a replacement for that board, but they cost a lot less because they are kits.
Are you not happy with rockcliff?...
Gecko might be a bit of overkill, but if you have the money, go for it.
What Toinvd said. Either motor will "work" with the driver, neither is going to give you much power.

Hey Al, do you have a sense of what the component cost was for that driver? I'd be interested in making a kit available if the price could be made reasonable.
Best I can do is 40 volts:

That's interesting. It does appear that the Smoothstepper plugin for Mach 4 has no place to set pulse widths. And your issue does appear to be related to the control signals. There is a slim chance...
I'm not sure I understand what you mean by "the same across 4 different drives"? Of course RF interference would affect all the drives. If all the cables are unshielded, you will get errors on all...
The Aliexpress link doesn't work except for you... e.g. it wants a login. Can you describe the unit you purchased? Find a sales link for it?

Yeah... no. Hang on... That's mixing things up reg.
Yes, you set the driver to the current rating of the motor (so looking at the motor current rating is right) but the OP was asking about...
Argh. I hate that. But with the title of the video in hand, a little google-fu brings us to:

This is really interesting Al. I went looking and couldn't seem to find that video, any idea what keywords I should use? Or if you have any other info on it, I'd love to hear.
Are they doing an...
Everything john said is 100% correct. However, since you said nothing about speed, and DID say you needed to save money, why not scavenge or salvage motors? There is a list of motors and where you...
I'd be curious to hear how you resolve the driver issue. As to your question 2, that should work just fine.
I'm just quoting this because it should be said twice.
Anti-gravity is real! It's called a spring. Or a rope over a pulley to a weight if your Z axis doesn't need to move fast.
As Jim said, its up to the driver, not the motor.
ultrasmurf, your description up top is really well written and I think it's pretty much accurate. The comments above are right, however... each motor may be a bit different and the driver for one may...
This is REALLY good advice. I use a different type of crip connection (one intended for a screw) only because I have a ton of them, but then I cut off the end and just use the part crimped to the...
The MassMind non-contact encoders would work nicely in that setup. 4000cpr, TTL AB, and easy to mount since they just use a little magnet.

This web page, especially the block diagram, may help. And there are links to other information. They key point is that the servo driver (the thing that is wired to the motor) must match the motor....
Glad to have been of help. I'm curious: Which of those ideas helped? And how are you liking the Duo / GAUPS / Tinyg / Chillipeppr setup?
Can't help with the motor id but this page may help you figure out the wiring and try them out

You can get basically the same kit from Luc in Europe:

Voltage is just a requirement for top speed. Higher voltage equals faster movement up to a point which is based on the inductance. 50 volts gets you the top speed.
Amperage gets you torque. The...

Just swap the phase wires on the motor. Power off first, of course.
The Clear path servoes are great; combined motor, encoder and controller with autotuning software. I made a video the other week about connecting them to a grbl. They are, however expensive as heck.
