Hello, today my printer start doing this error “bed_mesh: min/max points too close together” when to make adaptive mesh process with a bltouch probe. before doing that error printer work like a charm, even with smaller object. how can i solve that? many thanks

PS. i’ve already tried to comment [exclude object] in printer.cfg, but without success.
I use Prusaslicer with standard machine g-code

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Please attach it to your next post.

Somehow I assume that there are no parameters for the calibrate area (line 14) and it takes the default parameters for min and max with 0,0 for both.

You may set the default for max to 10,10

I found the mistake, when i imported the bed shape in prusa slicer, I didn’t put the bed measurement. Now it work
