I think you should remove the G32 from the Extruder start gcode. That's not a usual place to put it.

Also remove the G28 from bed.g. It's better to keep the commands separate so it's more clear about what is happening when.

Then change your start gcode in cura to be this

Works perfectly now

What did the line "G1 Z15.0 F1000; short move" that has now been removed?

Btw, I think it's really remarkable that you can remember all those codes

Nothing useful.

Another question

If the printer runs the G32 calibration, the nozzle leaves a little filament on each calibration spot, now I wondered if it is possible that after each print job, for example, 50mm retraction takes place so that the hotend is always free of filament, and that after the G32 calibration the 50mm (or more) is immediately re-fed.
