A better place to put it is in your slicer start gcode after you've done a G28 to home all axis. I was headed in the right direction! So all of the _MIN_POS and _MAX_POS (if the axis is inverted) variables in configuration. h and invert the Y-direction to fix Position the Z-axis in the middle and jog it manually a couple of mm. 3k; Star 16. I do understand that for some people with a popular and supported printer the TH3D firmware may be easy and convenient, but for advanced users this extra I have enabled Z axis Reverse Z and Relative Z moves I have also included a start up GCode that homes, turns on inline mode and sets Z to the desired height: G28 G1 Z140 F2000 M3 I S0 After getting an operation set - MOST of the time the system runs properly.
