So my early 90s VMC20 with the 88 control is acting up. Sometimes it takes 3 or 4 tries to even get the control to start up. Sometimes I get the crazy screen pictured.
Now the control will just reset randomly. It will be sitting idle or running the program and suddenly it stops and reboots. Tells me to jog to home position and enter CS. Strangely, when I go to jog mode it shows its actual position so I can just move it to zero in all three axes and cold start it.
It has been getting the unrecoverable memory error if it sits for a week or so without starting it up. I just re-enter the parameters and it is good to go.
Any ideas what the issue is?
