Sculpfun S9, when sending to laser machine cutting

I request support. Sending the cutting design to the machine, it moves very slowly, marks a rectangle instead of a square, or simply does not move. Thank you

Can you upload the file that is doing this?

I tried to cut a square and the laser marked and cut a rectangle. I notice that the movement of the X axis is very slow and modified
