I have bought this laser and control module and need help to connect it to a duet 6 for the best results.



What do I need to include in config file.
thanks for any help

Thanks for the link, I had already looked at that and have ordered a 74HCTo2.

Can I use the bed heater or the extruder heater or the extruder motor instead of heater 3?
If so what do I enter in config?

Thanks

Yes you can use any of the heater outputs or the fan output. See the page on the Duet3d wiki about controlling servos and unused i/o pins.

Thanks again for the information.
I see that some heater channels on the expansion boards are active high, are any of the heaters bed, hot end, or fan outputs PWM active high on the main duet 6 board?
thanks for your help

Al the heater outputs are active low. The reason is that the outputs of the SAM3X processor have pullup resistors enabled by default, so the default state is high. So active low is safer.
