The path error of the laser marking machine actually refers to the deviation of the marking size. How to adjust this?
1. First mark a 30x30mm square in the working area of the laser marking machine.
2. Use a vernier caliper to measure the square, and record the lengths of two sides, one for the x-axis and one for the y-axis. For example, the x-axis is 25.5mm and the y-axis is 26.6mm.
3. Enter the Parameter setting(F3) of the laser marking machine software Ezcad. Adjust the scale of Galvo 1, the Goal mark size is 30mm, and the Real mark size is 25.5mm, and then the scale of Galvo 2, the Goal mark size is 30mm, and the Real mark size is 26.6mm.
4. Click OK, and then mark again. Continue to measure the size with a vernier caliper to see if the size error is normal. If not, repeat steps 2 and 3 to adjust.
In this way, the adjustment of the path error of the laser marking machine can be completed.
