Hoping someone can help me out with this. Got the M3 built alright and did test movements using UGS. Everything checked out. I also ran a basic g-code file and everything was fine.
I then installed the Dewalt router...and the weight dropped the Z axis bearing plate down, relatively quick.
UGS still recognizes the board, but move commands don't move any of the motors (X,Y,Z) although the echo from the board updates position (for example, if I'm at 0,0,0 and send a Y+1 command, the stage doesn't move but the UNO board reports 0,1,0)
So, I think I have two problems: 1) I screwed up the assembly of the Z-axis bearing plate, and the spring isn't strong enough to resist the weight of the router. Is there something else I might be missing in this case?
2) Damaged the electronics. Is it likely just the stepper motor drivers or the entire shield unit? How would be best to troubleshoot this?
Thank you!

When the control is powered up you should have motor holding torque to keep from moving the axis by hand. If that is not the case then there is something wrong with the stepper driver boards.
I'm not sure about the spring adjustment on the Z axis.

Something is up with the electronics if it previously jogged but doesn't now. The router dropping could just be bad settings that need to be corrected, but the fact that you aren't able to jog indicates something is amiss.
Do you have 24 volts DC at the screw terminals? Is the blue light on your power supply brick?

I have a similar issue, M3 previously working correctly with no changes in settings. After working for a few hours, the Z axis had crashed when torque was lost (I had hit emergency stop because of a spotted loose clamp). After that, I get no torque and the Z axis moves when handled manually and gives little resistance. If let go from any height, the Z axis slowly slides down under the weight of the DeWalt.

How is your emergency stop wired? Sounds like the Z axis stepper driver is damaged.

I like using the pause signal for the e-stop. Then I can usually fix what's needed, then restart the router, push un-pause, and continue the cut.
