I'm sure I'm doing something stupid here but I can't figure out what. These are the starting commands from my gcode. As soon as I send it, my Genmitsu Z axis rises to the limit switch (about 100 mm) and I have to reset, re zero (both y&x, and Z), and try again. Can anyone tell me what line of this code is causing that?

What post processor did you use, and did you home the machine before you started. It looks like the generic Fusion GRBL PP. If you want it to work, home your machine at the start of each session, and use the OpenBuilds post processor. docs:software:fusion360 [OpenBuilds Documentation]
the stock GRBL post uses G28 which requires a bunch of knowl;edge to work correctly the openbuilds GRBL post uses G53, which only requires homing the machine to work correctly
