I have an OX CNC running Mach3 with a Super PID. I have about 63 hours on the Super PID. Today when I went to use my CNC the router fires up and goes to near max speed and then slows and speeds up to max and continues this in a loop. Nothing has changed with the system. The PID starts up normal and I can see the spindle detection. I rotated the router spindle and the spindle sensor works normal. When it powers up and goes to max speed the screen on the PID states Startup Failed and goes to Stop and then loops.

I have tried everything I can think to try. I went through every connection possible in the electronics box to make sure nothing came loose. M3 and M5 work fine.

I sent an email to Super PID but haven't heard back yet.
