The attached image shows results on the back of a mirror using LaserEtch by Jtech Photonics.
Note that in the second half of the etch/burn, the laser is occasionally left on in what should be whitespace. I believe the burn is not as complete in these areas as the intentional burn areas move at 240mm/min and moves between spaces are 6000mm/min.
Running these at different speeds may result in different, fewer or no errors, so I do not think it’s the gcode LaserEtch is producing. I get no communication errors in the repetier console, and no problems in the image registration.
–Maybe noise on the TTL line? I’m using shielded 18 gauge cable.
–Cheap driver overheating? That would make sense considering these errors occur later in the burn - how should I check that?
–Using two separate ATX power supplies, on for the MPCNC, one for the laser. Maybe it’s angry that I haven’t unified the ground between the two supplies?
Thanks for your thoughts on this!
