Hello CNCZoners!
I have build CNC machine to elements of mosaic. I am tuning it now, however I bump into problem I am unable to solve so far.
pieces I am cutting on it on Y axis are consistently about 0.2mm larger than X side.
I am now, while tuning the machine? cutting only a square 10mm side. so, X side is fine - 9.97-10.03 mm, but Y side is about 10.25-10.27.
I was trying to make some changes in stepconf of linuxcnc, but no luck so far.
on the photo is my X axis configuration. Y axis is exactly the same. I was trying to upload second image but for some reason it won't upload.

Any suggestions/recommendations, please?
