Axis Over-ride switch not working.
Posted: Tue 03 Jul , 2012 15:51 pm
Triac PC running VR Milling 5.
I've adjusted the 'Z' axis limit switch actuating bar to prevent the cutter going through the table if an offset is set up wrongly.
Machine in jog mode. Head jogged downwards until it trips the Z axis limit switch, everything stops and "Emergency Stop" is displayed. Normal operation I assume?
Press the axis over-ride button. After a few seconds machine seems to activate and "Machine Ready" is displayed. Continue to hold down button and attempt to jog head upwards. Nothing happens. Machine stays still.
Sometimes I can get out of this by clicking on the home all axes button. At other times even this doesn't work and I have to open the cabinet and release the Z axis limit switch manually. I've never suceeded in jogging out of the situation though.
My background is in electronics, so I'd have no problem tracing the wiring from the switches back to the control cabinet. Thought I'd ask here first in case I'm doing something wrong though.
Thanks.
