Hi
I prepared test square which dimensions are 25x25mm in X and Y axis.
Unfortunately printed one has X=24.90 and Y=24.70 mm.
Any suggests what is wrong ?
Thanks

It’s possible you need to calibrate your printer.
Design 2 L shaped objects : one 20x20 mm and one 50x50 mm and a low height (5 mm). Print then at the same place on the Repieter grid, with the edges aligned with the X and Y axis. Print them 2 times with a low speed. Use 0.6 wall thickness, 75% flow and 190° for PLA.
When printed, check if the difference is repetitive and proportional to the length. If it is, compute the difference in % and make an average value with the differences.
You can then modify the steps/mm value in the EEPROM adding the computed % to the value for X and Y.
