3.5 B3 Toolboard stepper intermittently running backwards

@Exerqtor Are you sure DO is right and not D0?

[Exerqtor]

@oliof I copied it from the docs since I was unsure about the exact same thing 😆 So unless it's written wrong there as well it should be correct.

@Exerqtor Which docs? I've just checked the source and there is no pin called either D0 or DO as far as I can tell. What pin are you trying to drive the neopixels from?

The only pin that supports it on a Duet 3 Mini, which from what I can see lacks a proper explanation on what the "DO" pin is actually called. "ctrl+f" search for DO here and look at the 14th entry. Thats the only mention of it (that i'm able to find) in all the docs / schematics.

It's also just called "DO" in the schematics:

@Exerqtor the dedicated LED port is known as "led" in the firmware. This needs to be added to the documentation.

@dc42 Then i bet a beer on the problem being solved for both me and @ctilley79 now that we know that. Thx!

Does the M150 P parameter to work for you on this firmware build? I'm also using RGBW neopixels. The P parameter does nothing right now.

I don't use the P parameter, only the R/G/B/W component "amount", it should yeld the same result although you would have to play around with the values to get the same effect.

@ctilley79 you are correct, the P parameter doesn't work for Neopixels. I will correct this before we release beta4.

May I know how to define M950 for Duet2Wifi? It can use M150 directly before, however it is failed and need definition first now. But not pin name found...

Add the source code to confirm my finding.

[hestiahuang]

so don't miss Duet2Wifi...

@hestiahuang thanks, this is now fixed ready for 3.5beta4.
