Hello, I have a Sculpfun S30promax, I have been operating the program for approximately 11 months, today the problem occurred to me as follows: - In the Move Option in the console, I can move with the exact measurements in X and Y, But… - when I start to cut, in Y it cuts me 55mm higher than the design, causing great deformation in the work How can I solve this problem? ---
