Atomstack A70 Pro / Windows 11. Using either 35 watt or 70 watt output, laser beam will shutoff mid cut and skip an area. This happens on line (cut) as well as engrave (image or fill). The location of the skipped area seems to change from one file to the next, but always skips in the same place in a given file.
Perhaps a connector coming loose as the laser head moves around or a broken wire in the cable coming apart as the cable flexes.
Set up a rectangle or circle around the suspect area at a very slow speed and barely visible power. You can then gently wiggle-n-jiggle the cables / connectors while it’s in motion: when it flickers, you’ve found the problem.

Checked the wiring and no effect on the issue. I’ve tried constant power mode with the same skipped result. I also tried reverting back to V 2.1.03 since it seemed to start after I updated. Still does the same thing with the older version.
When I tried to cut a circle at low speed / low power, the laser didn’t fire for the first few seconds, then fired as normal, then about half way it stopped firing again for about 5 seconds, then started to fire again to stayed on till the end point. Jiggling the wires throughout the cut had no effect.
Just a suggestion, but could it be the driver board on the module.
It could be, but it will be difficult to determine, since I will need to get a new control board to confirm.
I tried moving the graphic from the left side of the bed to the right side of the bed so the laser cuts in a different location, and it worked fine, thus far. So, I’m guessing not a control board issue.
Tighten all your connections on control board. I had a problem where it messed up intermittently but in the same place, and one of the wires was loose.
Classic indication of an intermittent wiring connection issue. Now you just have to find it.
Which confirms a wiring / connector fault, because the blackout is related to the physical position of the layout on the platform.
However, you now have a simple test to confirm the fix when you locate the fault!
