Plasma table motion stopped dead during first cut after initial setup
Posted: Thu Nov 03, 2022 4:27 pm
Greetings...
We have a home-brew plasma table running DMM DYN4 drives, Intel NUC running Win10 with all updates, Hypertherm 45, Acorn board circa 2018, and the new Centroid plasma kit (green board). The previous incarnation using a Proma 150 THC out of Czechoslovakia has been in service for about three years. While the unit had its idiosyncrasies, it has performed just fine with reliable motion in all axes.
We were in the midst of setting up the Centroid plasma controls, stepped through all the setup procedures (including torch calibration and 4-inch line--it looked really nice), and thought we were all good. We were about 15-20 inches into our first cut after the prescribed setup procedures when the torch (Z-axis) started rising, then the torch stopped and all axes stopped dead.
We have since gone through multiple troubleshooting steps, but cannot get any axis to move… drives do not lock. Acorn has a heart-beat. We’re unclear on what to do next, and need some help.
Current report is attached.
Thanks for your attention… much appreciated!
David
