I have a Ortur Laser Master 2 and use it to cut 1.5 mm wood using about 15 passes at 750 mm/m at power max 100%. I don’t believe I made any changes to the setting, but now the laser is not burning certain parts of a design, but still moves along as it should. I’ve also noticed that the burn is not consistent and leaves little gaps in the burn line.
I did a visual inspection of the machine and did not find any burn wires or such. Any assistance it troubleshooting this issue is greatly appreciated.
I’m sure others will chime in soon but I have an OLM2 Pro (which has a somewhat better laser) and it will cut through 1.5 mm ply in one pass. I suspect that you are running it WAY to fast. My settings are 175mm/min @ 80% power (YMMV). It isn’t recommended to run your diode at 100% unless absolutely necessary. I would start in the 175/80 area and adjust from there. Hopefully others with way more knowledge then me will provide their wisdom.
I have the same problem. Do you havy any new information?
Same here!
I made a drawing myself in Lightburn and tried to cut it today.
On the first run, the laser just didn’t cut some lines. The head ran them, but the laser was off. On the second run, it did cut some of the uncut lines - but not others. One corner of the drawing was completely ignored, even though the drawing is closed there.
Does anyone have any idea what this could be due to?
Check your wiring from the controller to the laser module. Make sure there are no frays. Take off the connectors at the ends and insect them. Do you see any burning or discoloration on either the cable sides or board sides?
If it’s not a cable issue then check your power supply. Have you been getting any connectivity issues? Check for voltage if you’re able to try swapping power supplies if you have another one available. If neither of those then possibly laser module or controller issue.
One test, if the laser head is not moving is the laser light steady? If so, try wiggling the wire to see if you can get it to turn off. Then that pretty much guarantees a connection issue. If not the wire then the connectors.
