I’m relatively new to CNC. I had the most weird/impossible thing happen with my Shapeoko 4 XXL. All axis just reversed + for -.
I had homed it, zeroed it and started a cut. Then it did a z- move about -.150, it was programmed for -.015, yes I triple checked. Then I stopped the machine and homed it. I software disconnected it, reconnected and tried to run the homing. It slammed into the table.
I tried many things within g-sender, nothing worked. I downloaded and tried carbide motion and got the same result. I got it started without homing and did a manual z+ move, it went down, x+ it goes left, y+ it comes toward the operator. This machine was in operation normally just before all this. What the heck? Where do I start to try to fix it? Thank You
