I just purchased a Shapeoko Pro XXL. My cnc program consists of two contour paths. The first cut just fine. Then when the second contour started the z axis plunged into the table. See photo. The burn marks are from the collet nut on the router. That is how far it plunged. I shut down the machine mid program. Then started the machine back up and initialized. The cnc failed to home. The z axis would go down instead of up to the limit switch. The machine finally homed after multiple attempts to restart the machine, manually push the router to home position, and various other things. The z axis switch wires are not crossed. Not sure what steps were the solution to get the machine to home properly.
The machine is not wired backwards. It has been running just fine up to this random moment.
Attached is the g-code too.
What happened? What did I do wrong? The help is appreciated.
My dust collector, Supermaxx 1.5 HP, was connected to sweepy dust boot. It has a lot of power and I noticed as the flex hose contracts (not collapses) under the suction it exerted force towards the head unit. The dust collector is behind the cnc.
