Laser head moving to the right and keeps going

Post by JFox »

For some reason yesterday when I turned on the machine and was about to cut a rdworks file the head of the machine ran all the way to the right of the machine and then did not stop when it reached the end of the frame. It wanted to keep going and beat itself up against the side of the machine. Has anyone experienced this? I have a video here https://www.dropbox.com/sh/gxdojbm309p3 ... ubRAa?dl=0
Thanks in advance for help.
All the best,

There are three possibilities:
1.Wrong pulse setting
If your laser cutter has a wrong pulse setting, the laser head might keep moving even it reaches the edge and hits the boundary.
If that is the problem, you need to reset the pulse parameter to fix it.
Please refer to the following link to reset the pulse parameter.

2. The limit switch does not match the controller
Most laser cutter controller only works with the NPN-NO type switch. If you use other types, it will leads to the laser head hitting the edge. Please choose the correct limit switch to fix this problem.

3. Wrong wiring
If wiring of limit switch is wrong, it also leads to the laser head moving over edge.
Please refer to the following pictures to correct the wirings to solve the problem.

Hi JFox
i think the problem is caused by driver's controler ,and you can ask your manufacture to change new one for you!

I had a similar problem with my Mini-60. The problem was caused by wires poking out from the insulation and intermittently shorting out which mimicked the limit switch being tripped. Once the machine thought it was at zero it took off and hit the mechanical stop just as you described. Follow the wires from the limit switch into the cable chain. It was hard to spot.
