Idex mesh leveling with T1 active
-
My idex machine has the z probe attached to T0. If T1 is the active tool it tries to home z and probe the bed using T1, which does not have a probe attached. I realize the simple solution is to make sure T0 is active when running G28 or G29, but is there any way to ensure that if this is accidentally done with T1 active it will still probe with T0? If you're not paying attention and trying to home z or run mesh leveling with T1 active it crashes the tool into the bed.

Alter homeall.g and mesh.g to select T0 at the start so that when G28 or G29 get called it will switch to T0 if not already active.

@phaedrux I had that thought, but that can interfere with the print jobs if mesh leveling is done at the beginning of each print. At least in Cura, it outputs the tool command for the first tool used during a job before it inserts the start gcode. This means if the job is supposed to start using T1 and there is a T0 command anywhere in the start gecode then the job will start using T0 rather than T1. Thus, I have been trying to avoid any use of tool commands in the start gcode. This is pretty annoying though, so I might have to look into changing how Cura outputs gcode in the back end instead.

If you're really worried about that use start.g to do the print prep. It takes effect before the print gcode is executed.
T0
G28
G29
; cura code takes over and selects whatever tool it wants. -
@phaedrux I forgot about start.g, thanks for reminding me! I will give that a go.
