Hello good morning, I have had a problem for a long time when I want to do the REF ALL HOME. I have a milling machine converted to CNC with mach3 and a CSMIO-IPM board.
When I press the ref all home button, the z axis should go up at the set speed (I have it at 50%) until the end of the switch to mark the 0 machine, but only sometimes instead of going up, it goes down at full speed and crashes against the table.
It doesn't do it every time I ref all home, but it's very annoying and dangerous not knowing when it's going to happen. I already broke several expensive tools.
The X and Y axes are working correctly.
Someone has an idea what might be happening.
Thank you.
