Challenge jogging with motors appearing to get stuck

My Pro4848 has been running very well and recently replaced the spoil board, re trammed and squared the machine. I booted up the machine yesterday morning, did a spindle warm up, homed the machine and then went to jog to start a program and all axis motors are appearing to get stuck or hesitate when I attempt to jog. Its not fully stuck but appears to be intermittent. I have logged a ticket with Avid support but I have not heard back as of yet. Any help from the group would be appreciated to help trouble shoot this issue.

Thank you!!

This sounds like a computer issue, but it’s a bit hard to tell.

Avid support is on Pacific time so it may be a bit until they get back to you, but they are very good at troubleshooting this sort of thing so I’m sure they will have you up and running very soon.

If you wanted to to some troubleshooting you can check this link: Mach4 - Troubleshooting

There is a specific section that deals with symptoms you are describing.

The intermittent jerking of the motors could be due to one of two things.

  1. You have a loose connection, check all your connections, open clean reset.
  2. Static, check your spindle if you have dust clinging to it. That will indicate static. check all your ground connections. You must have a grounding connection all the way tot he spindle. Spindle is the biggest creator of static.

Thanks for the Feedback. Grounding is good, I am fortunate to have a good friend who is a electrician and was able to rule out any electrical grounding issues. I did swap the network adapter (USB C adapter to my laptop) and that has solved the issue.
