The motors on my machine move in spurts if at all. If I uninstall and reinstall Mach3 they will work for 5-10 minutes. What is causing this?

Please attach the xml for the profile you are using and I can have a look and see if I get a problem.
Which Rev of Mach are you using.

How do I do that. I am very green when it comes to this. My machine worked fine from the factoru but now screws up all the time.
I am running Mach 3 version 2.00.065 if that helps.

might be best to update to the latest lockdown version.
To attach the xml browse to your Mch3 folder and copy the xml for the profile you use and then paste it to your desktop and rename it to sully3535.xml
You can then use the additional options in the reply page to attach it.

Thanks. I downloaded the latest lockdown version and it is working fine so far.
