Laser control failed
-
I made the circuit board according to the instructions on the official website, but after connecting it to the duet, it can’t work properly. I can’t control the laser switch and intensity using instructions such as M3.M5 G1 Sx.
I have measured it, the power supply is normal, and my laser module also meets the specifications. The pwm port has a 5V output, no matter what G code I use, the 5V voltage does not change.
I made M452 C "exp.heater3" R255 F200 into a macro, and I opened it when I needed it.
The above is generated using Google Translate. If there is any unclear description, please let me know. -
Can you provide the results of sending M122 so we can get some more details about your setup like what duet board and firmware version you're using?
Can you also share your config.g and other files that are being used to configure.
Showing a photo or diagram of your wiring could also be useful.
