G-Code, CAD, and CAM discussions / G28 conflict
« on: February 06, 2017, 11:17:51 AM »
I'm running Mach3 to run a router. When I home the machine all axes move to the zero position with z at the top. When a program encounters a g28 g91 z0 (any time it needs a tool change for example) the z rises up to the limit switch but triggers an e stop rather than a limit and the program must be reset. Any guidance on settings? Thanks
