I have the 10 watt Endurance Laser and I’m using Lightburn for software. I have the KeeYees arduino controller using GRBL 1.9g.
My issue is the power is backwards. when setting up a test using the same speed and stepping the power down by 10% each time the current goes up instead of down on the controller readout.
The voltage remains the same at 5 volts but the current at 800 mm/min at 90% is .53 amps the next step 800 mm/min at 80% the current is .72 amps at 800 mm/min at 30% it’s 2.72 amps. I don’t have a clue as to why this happening. I’ve checked the S-Value max in Lightburn and the GRBL settings and they match. I’m using the original M01 board that came with the laser as the driver. This kind of explains when I fire the laser at 20% in the Move section it burns a spot.
