I purchased Roly lasermatic 10w 3 years ago. Roly does not sell the Lasermatic 10 anymore so I recently purchased Laser Tree (LT-80w-AA pro) module to use on my machine. I use windows on my Dell laptop.
The Lasermatic 10 would only engrave and cut on the left side of my machine. I believed the module was broken and that why I purchased the Laser Tree. But the same problem continues. I have looked on Youtube, Facebook and Lightburn to see what the problem could be without any results. I have checked all the connectors I could find on the machine and cleaned everything. No results.
Does anyone what the problem could be?
Quite likely an almost-broken wire in the cable along the gantry where you can’t see it. The cable flexes as the laser head moves along the gantry, with the wire strands separating at a particular spot.
If you can identify the position along the gantry where the engraving stops and see the entire length of the cable, the most likely breaking point is where the cable shifts as the laser head moves near that position.
Because one wire is broken, another is likely to fail for same reason, so replacing the entire cable is the best bet.

Could be due to an Internal Cable Pulling / Cable Fraying
As the laser head moves across to the right of the machine the main cable gets pulled and stretched. If there is a fine crack or loose pin on the X-axis PWM signal cable then the connection will be made on the left-hand side. However, as soon as you move the head to the right, the cable will tear causing the laser module to lose power/signal.
To quickly check this issue. Home the laser head on the left-hand side, turn on the 1% framing/focus laser and manually push the laser head to the right of the rail to see if the laser flickers off.
