Title: Uncommanded rapid movement P1A-S
Post by: Trebleplink on May 18, 2026, 11:31:14 AM
Yesterday I installed the pendant and I like the features BUT it is dangerous to use.  I'm running Mach3 v 3.********* on Windows XP.  The plugin is 3.3.0 (I updated firmware today - Monday - same results)

2 problems:

When in step mode, as I am turning the mpg, stepping 0.001 at a time, it will reverse direction and move at full rapid speed back. I'm not sure if it is returning to where I started or not, but it is something like an inch or so. It does not seem to matter what the increment is set on. It's un-commanded movement at rapid speed. So I cannot use it.

Sometimes the mpg goes to sleep. The lcd shows the dro value OK, but the mpg does nothing, and there is no way to fix it until I restart Mach3.

Anyone seen this problem?  I'm hoping to hear back from VistaCNC soon ...
