Newly assembled crossfire pro, seems like the y axis motors are not synced up. 1 starts moving slightly before the other. I
Swapped y axis plugs on control box and the opposite motor takes off first. Any suggestions?

Check the coupler on the slow side. Take a black marker and mark the coupler, motor shaft and the lead screw. It may be slipping. This is a know issue. Also make sure that there are no burn pins on the DB9 connections. This also a know problem. The must be screwed down tightly before testing motors. The DB 9 connections are just barely capable of this job. Any loose connections will result in burnt pins.

@Trentholland78 Welcome to The forum
The other thing to look at would be whether the dip switches on the drivers or in the correct position.
See if one of the y drivers is set up different

Dip switches were in correct positions.
1 pin on both y axis plugs very slightly smoked.
Salvageable?
Plugged the y axis plugs back in machine and it seems to be fixed. Both y axis motors are in sync.
Pulled the z axis plug off to check for charring as well because it had been “binding”. Z axis had no charring.
Plugged the z back in and now it won’t feed over 50IPM with out binding.
Do you still have the cover off the control box?
Put a meter on the power supply inside. Check for 36 vdc.

Yes sir. I checked the voltage and it was 36.36vdc.
After some lubrication and some action on the z axis it started operating properly.
Hopefully it’ll run for a while without any more issues!!
Is there any upgrade for the connectors? Can u run dialectic greese in them?

Dielectric grease would be ok. The best thing to do is unseat and reseat them, making sure they’re home. Also make sure the screw terminals are tight.

Just tried first cut and the y axis as well as the z axis are acting up again.
Y axis motors aren’t synced, and the z axis won’t pick it self up anymore.
Everything is intermittent.
Send a couple of pictures of your setup—computer, wires connections.
It my be emi or a ground loop issue.
Also make sure the printer style usb cable end is not in contact with the control box housing.
One more question, if you run a project on dry run does it work without issues?

Is the Z binding or is the coupler between the motor and the lead screw slipping?
There have been a number of Z axis units with loose couplers lately.

I talked with him on the phone. His USB port was contacting the housing of the control box. After we got the Y and X working correctly, his Z axis was locked up solid, with the Z cable unhooked. He had to leave, but I sent him the Z rebuilding guide I had on file.
He going to call me tomorrow.
