I also tried each driver with each motor.

So where are your at? You have the one good motor working? I was under the impression motors were working but you want to upgraded to a little better motor?

Working in the sense I can make them move. Nothing past that. They are properly wired but they thump no matter what I do when power is applied and they move on their own when no command has been inputted.

As I mentioned, the thump you are likely hearing on power up are the motor rotors locking.
When they "move on their own" are the connected to Acorn and Acorn powered up?

Video please....

I am considering the KL34H2120-42-8A for Automation Technologies. I cut solid wood, mdf, baltic birch plywood, acrylic, Corian (solid surface materials).

When one motor was connected to the drives the worked fine. It wasn't until all three motors were attached that problems arose. I could not home the machine because in the process of the last axis homing, the z-axis would move upward and trip the home switch again. I tried to see if the motors would run smoother at lower speeds, that did not help. I tried 24 combinations at different microstep settings as well.

Why not a simple 4 wire stepper?
The 1200 oz in motors should be adequate for what you want to do.

I need a keyed shaft. Did you not see the video attached? I have tried powering Acorn before the motors and the other way around.

Please repost a link.
I am unsure exactly what your issues are. I have a NEMA 34 running quite smoothly on the bench. It does thud when the drive powers up, but that is the Rotor locking.

You also really should consider using shielded wire for the step dir signals from the Acorn DB25 terminals to the GR214's

All wiring is shielded. Have you tried hooking up 3 motors?

Too much going on at the same time without focus. You keep mentioning movement without a command. That is as bad as things get so you need to start there, ignoring everything else. Please do the following and report at which point things break.
[I'll try to keep track of the power, but in case I make a mistake, remember to manipulate any wires only with the power off}

1. turn all power off (Acorn + motor controllers) and shut down the software
2. disconnect Acorn from the three controllers
3. disconnect the motors from the controllers
4. disconnect the motor power from the three controllers
5. connect X motor to the X controller and X controller to its power supply
6. power on the controller power supply
7. there should be no movement; the X motor will lock when the controller is turned on
8. power off the controller power supply
9-12. repeat steps 5-8 with Y not disconnecting anything
13-16 repeat steps 5-8 with Z not disconnecting anything
17. if you got here you had all three motors connected and no extraneous movement on power on
18. connect Acorn to the X controller; turn on Acorn + motor power supplies; don't start the software
19. make sure you can cycle all power without extraneous movement in any of the motors
20. start the software and make sure you can jog X without any movement on Y or Z
21. stop the software and shut down all power
22. connect Y and Z controllers to Acorn and turn on all power and start the software
23. make sure there is no movement
24. jog X; there should be no movement on Y or Z
25. jog Y; there should be no movement on X or Z
26. jog Z; there should be no movement on X or Y

Please report at what point you see the first problem.
Cheers

video sounds like to me this is case of motor phase wiring being messed up. :?:
