Hello,
I have a custom made printer with CoreXY mechanical and build volume 50x30x25 cm.
It is built on Hiwin and rock-solid construction but still, there is a problem with not round circles.
A was thinking that it is backlash effect byt tightening/losing the belts done non-results.
A have also change the pulley on stepper to a bigger one and do kind of tightener
(like this : [imgur.com] )
But the circles are flat on 2 sides (kinda straight lines in X-axis direction). Is it something that I can correct by firmware (Marlin 2.0) ?
Here is the photo od the print and the drawing with dimensions :

As you see, there is a gap in the wall in 45degree and the wall on second 45 degree axis is too tight.
Thanks in advance.
