Can you post your homing files? Perhaps you have something strange going on in there.

Nothing out of the ordinary there. What does your build platter image look like in Cura? I believe it blanks out areas it thinks it cannot reach.
Are you sure belts or pulleys are not slipping or motors skipping steps?

In the code I entered the position of the nozzle (distance nozzle to end stop) as the starting position: 50 and 115mm:
M208 X50 Y115 Z0 S1 ; set axis minima and the same in the slicer settings:
Is there a misconception here?

Yes I think so, For those fields you could probably leave them as 0 and see if that improves your situation.

I think so too. From a firmware perspective, the axes minima are relative to the position of the end stops. But the slicer has no concept of end stop switches, let alone their positions relative to the build surface. So I think the slicer axes min should be zero and the max should be whatever the travel length is. Otherwise one would be doing a double compensation.

My German is a little rusty, so I had to open Cura to see the English. The Druckkopfeinstellungen or Printhead Settings tell Cura the general size of your print head, so that if you are printing multiple objects consecutively, it will lay them out to avoid the print head hitting the existing objects on the bed.
At 115 and 50 mm you've told it your print head is extremely large.

Hello, I was on a business trip for 1 week and was only able to try your tips now.
In fact, after I set xmin and ymin to 0 in Cura, the printer printed the entire circle...you guessed right! However, the start position in the control panel changes. I suspect something is still wrong in the Cura startup code. Can you give me a starting code for Cura that is as simple as possible? Here again the start and end code from Cura, which I took over apart from the speeds...

@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 0Most 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.
