General Mach Discussion / losing z-axis motor function
« on: November 30, 2015, 05:35:21 PM »
Hi All,
I recently purchased a pre-built 3 axis router and am stuck on a problem that is over my head. I'm new to CNC and just getting up to speed on how the wiring for all the parts hook together to work with Mach3.
My problem is that after the machine is running for a few minutes, I lose control of the z-axis... it's as if there is no more power or communication going on any more. I can freely turn the pulley by hand to move the axis up and down. I have to turn off both Mach and the controller to regain control. They x and y axis work fine.
I've checked for loose connections, I've swapped the y and z servo drives and my next step would be to swap the y and z servo motors.
There is no diagnostic information generated at anytime while the machine is running.
Is there something basic that I've overlooked?
