Sometimes when using the engraving machine, I found that the position of the engraving is wrong. I always blame the wrong position. To eliminate this problem, we must first check the reason. The following methods can check out what is wrong.
1. Check if the belt is loose and the synchronous wheel is slippery.
Second, X, Y two-axis racks have clearance
Third, check the driver and motor
Fourth, the drive line is loose. Try to fix it tight.
5. The limit switch fails. When the system returns to the original point of the system, the limit switch is closed and popped open, and the limit switch can be changed.
