Mysterious Z150!

[handyandy]

Hi I am trying to find a Z150 command that gets executed every time I start print.
I have looked in the Cura startup code, start.g and pretyty well everywhere else!
What is the start sequence of files called when starting a print? Or could this be in the firmware?

@handyandy start.g is executed before anything else and then its whatever is contained within the gcode file

@jay_s_uk Thanks for that.

@handyandy This still does not explain why when starting a print the nozzle goes up to Z150 (shown on the console) There is not one mention of Z150 anywhere in the macros, system files that I cant find!
Still puzzled... must be in the firmware coding?

@handyandy post your homeall, homez, first lines of your gcode file up to the point it starts extruding and anything else thats called

@jay_s_uk This is somewhat related, but can you send parameters from your slicer start code to /sys/start.g? The only way I've found to do it so far is to create a separate macro and call that via

M98 P"/macros/whatever.g" H[hotend_temp] B[bed_temp]

However there doesn't seem to be a way to pass that parameter to the start.g in the sys folder that is executed automatically.

@ctilley79 you can't send parameters to start.g as it's executed before the gcode is
