Machine. It just stopped. Panel was dead. Had to cut the power to reset. When I fired it back up the origin was .236 off on Y. Good thing it roached the endmill before it got to far. Reset the origin and called it a night. When I went out to finish it tonight it was .236 off again back to it's original origin. So it has 2 issues, the main board is locking up and the Y axis limit switch is not consistent. Replacement board off egay is 250$ but I need to figure out how to save and reload all the parameters. Assuming all the parameters are correct. With a machine this old it's all a crapshoot. May require a call to Haas. This is not something that I will put up with.
