Shopbot "Jerking" After 3 minutes of use

[Nstep007]

I know I have a ground on the gantry. It's a older bot

Just to cover the bases, have you checked all the pinions and motor mounts?

Power to the motors? It could be a simple mechanical issue not related to the other stuff.

[Nstep007]

Have checked everything. Gave machine mouth to mouth. All motors should be fine. Because every 3 minutes, eve r u axis does it. I don't know whatelse to check for

[jerry_stanek]

check that updates are turned off and check your usb settings they may be set to suspend. Control panel power options advanced power options.

Can't seem to find advance power optins on windows 8

[Nstep007]

Ok, i found it. And it was disabled. Don want to enable it?

[Nstep007]

Either way, still doing the same thing

Is there any correlation of the location of the router/spindle or gantry to the bot’s misbehavior? Or just time? I had a broken wire that worked fine until certain combinations of X,Y & Z caused an intermittent connection… it acted similar to your description.

Do you have another computer you can try to see if the problem goes or stays...

No its just time. I move with key pad. And every 3 min it jerks. Have tried difference tcomputer as well. Still same issue

[Nstep007]

Now when I go to move the machine. I'm getting a "emergency stop button on" error... but the stoproblem button isn't and hasn't been hit
