Hi everyone .
My laser machine working without problem about 6 month and then i change the controll board from arduino uno to stm32 hand maded board and it work fine but when i engrave some photo with it it show some strange problem some time its change the x direction and picture location change . Then because of it i get back to arduino uno and test it but now when you get it to home or frame or any thing you want to do x direction got some lag sometimes . Some time lag but then working fine . Iam thinking maybe it socket problem then soldering wire on the board but it not help . Any has any idea ?
