Hello,

I am setting up a DLP printer with arduino 2560 and ramps 1.4 and nanodlp.

I want to control the mosfet outputs D8,D9,D10 directly with GCODE from the nanodlp interface so that I can turn ON/OFF my UV LEDs.

How can I do that?

M106 M107 do not work.

Thanks in advance.

Giorgos.

Giorgios,

Our firmware has been rewritten for use of a laser and for use in DLP systems. A couple of those are system reserved. So technically speaking you're going to need to probably pick the heated bed output since we didn't touch that output, then turn it on the the firmware but disable the heater temp check, and then you can use the codes you wish. But you'll also need to set PWM when you turn them on using the codes, this will effectively end up controlling your LED brightness.

Using the readme in the firmware files, as well as editing configuration.h will get you there.
