In the middle of cutting a giant piece of art, I got an IHC warning saying to check the slack on the lines. There was plenty so I figured out that the Z axis would not engage. It would go down but not up. I tightened everything and cleaned it with compressed air. Still nothing. I’m thinking it’s the motor. Has anyone had this issue before? I’m beyond frustrated. Literally every single time I use this machine, something happens and I spend hours trying to fix it. I’ve barely cut 10 projects on it.
