I can get PWM output using M42 command. I tried to track the differences between functions that are writing pwm values in M106 and M42 command, but it seems that it points to the same function in the end... That's why I'm asking on forum.

Yes, I'm sure. I've changed the version info file already to make sure that it's really upgrading the firmware.

Hi,

I'm trying to configure additional SX1509B (address 0x71) to act as fan output.
Facts:
Duet<->SX1509 connection is working (I can see the Duet v1.02 + SX1509 in DWC),
Mosfet and fan is connected to pin 15 of SX1509,
I can control fan using M42 P135 Sxxx command,
Found out that pin number 135 in M42 translates to pin 235 in analog write function.

I want to control it with M106 command, so I changed pin number in Pins_DuetNG.h for fan3 from 212 to 235. Recompiled firmware, uploaded it to my duet. I can still control the fan with M42 command, but M106 doesn't work. Any hints what else do I need to change in firmware to support that?

Hi,

I'm experimenting with different types of filament monitors and would like to use the protocol that is implemented in RRF 1.20 to communicate with my custom boards (no point in redoing that).
Could you please provide me with any information regarding signals I have to send and proper timing? Simple sketch would bo more than enough.

Thank you in advance!
