I have a problem I can't get out of, I'm sure the forum can help me. I bought a topwisdom laser cutting machine and it mounts the tl410c board. I oriented all the mirrors with precision but it remains a huge problem, when I go to cut or engrave something, the proportions are completely wrong (squeeze and enlarge anything), for example a circle becomes an oval. Surely there is something to calibrate, but I can't get out of it, can you help me? Thanks in advance.
