please help me about the problem of Sculpfun S10

Hello friends!
I just used the Sculpfun s10 machine but I can’t laser cut the shapes I want. For example, circles are not perfect, the same goes for straight lines and squares. Currently I am using the trial version of LightBurn 1.4.01.
Does anyone know what’s wrong? Please guide me how to fix it


You need to first calibrate the mechanics carefully. This is not done via factory (impossible) and needs to be done before starting to work. There are multiple things to check, I suggest taking at least an hour or more to get this done. The guide is here:

And after calibration, your speeds might be too high…
