@axiom Moin axiom,
As „Start G-Code“, this here should be sufficient:G28 ; Home M83 ; set extruder to relative mode G92 E0 ; reset extruder’s relative position to 0
Most other instructions to prepare the printer for a job should better be written into the start.g macro on SD card.
I don’t quite understand this here:
However, the start position in the control panel changes.
With „control panel“, do you mean DWC, PanelDue or something else?
Generally, it’s quite simple. In your Druckeinstellungen, you told Cura about the size of your printer and the origin of the coordinate system: „Ausgang in Mitte“ (BTW: strange translation of ‚center origin‘) is deselected, so the origin should be front left. At least, that’s what Cura assumes.
Now, depending on where you place your print object in Cura, this should correspond to its placement on your print bed … as far as you defined the printer’s X/Y origin to be at the front left. If the position doesn’t match, there’s something wrong with either the size values in the Druckereinstellungen of Cura or with the axes-settings of your printer.
