It would be nice to be able to set a timeout period where the printer would go to sleep after being idle for that period of time. This would make it easier to leave the printer on, save energy, and probably make it safer when a print has finished an no one is around for a while.

@dc42 I have been working on modifying the E3D toolchanger code to work with the Duet 3, so I guess I just didn't notice, but that's a great point! Though that still doesn't solve the bed mesh problem right? I have attached my config.g and my homez.g @droftarts

homez.g config.g

@Danal io4.in appears not to work either. I also added the K0 to the 558 command just in case there was an issue there. still get the G28 Z failure

io3 appears not to work either. I will try io4 quickly.

So currently just using

M558 P5 C"io0.in" H3 F360 T20000

and when it gets to the Home Z scripts, I get a "Failed to enable endstops" on G28 Z

I am pretty sure before that I only had the M574 command, and the bed mesh compensation was still manual. If I only set the M558, how will it know which pin is the Z endstop for homing?

I am trying to set up a non-retracting switch as both the Z-endstop and the Z probe for mesh leveling. Currently, I have the following lines of code:

M574 P"io0.in" Z1 S1 ; Set Z endstop probe
M558 P5 C"io0.in" H3 F360 T20000

The z-endstop works correctly, but trying to run bed mesh compensation causes it to force manual leveling, which means something is wrong with my z-probe config. Anyone know what I am doing wrong?

Yeah, my main thing is I still use small 5V blowers for some cases, so its sad to see the 5V option gone... guess I will just need to use a buck reg. Thanks for the help.

I have both 24V and 5V fans that I need to connect to a Duet 3. On other duet boards, this was accomplished just by adjusting a jumper that either set voltage to V_IN or 5V. On the Duet 3, I am confused what the jumpers on the diagram are telling me. It seems like it can take voltage from either a 12V-36V power source, or 12V, but it doesn't seem able to drive 5V fans from what I can tell on the diagram. Currently, I am only powering the board with a single 24V power supply.

Can someone help explain how this works and correct my understanding? I would like to avoid frying anything through trial and error

@dc42 Thanks, that did the trick

I used to have my printer set up as M667 S1 X-1 (CoreXY with the x axis reversed). With the command now deprecated, how can I recreate that motion with the M669 Kinematics matrix? I don't really understand how the matrix works.
