Erratic tool release issue
for the last couple months i have been experiencing an erratic tool release during power up of the machine or when i push the MDI button.
it happens intermittently and when you least expect it the drawbar will start unclamping and clamping non stop,usually resulting in a tool falling out of the spindle.
i have disassembled the z axis cover and cleaned and checked the wires and connections to try and alleviate this problem but i believe it may be some sort of electrical component or circuit.
before i look any further has anyone had issues like this before and what do you suggest?
thank you in advance
