Duet3 issues

BlueDust

The fan didn't turn on at all while this was running. I just started the print over again, and can see the fan is running. (I generally start the fan after the 2nd layer, and gradually increase it.)

EDIT: FAN... The fan didn't turn on at during the first attempt of this print.

Which firmware version are you running? Are you using standalone mode or running witb SBC attached?

@dc42

I am running it with an attached SBC (RPi 4), but not doing anything else with it.
Duet3 is running 3.1.1.

Does the fan work if you manually send M106 S255?

Work is progressing on 3.2 beta and a release candidate should be coming pretty soon. There are a number of improvements and fixes for running an SBC.

BlueDust

@Phaedrux
I didn't send M106 to the printer when I saw it wasn't working, but quickly went to DWC and turned the fan on 100% and it worked. I have printed 3 calibration prints like the one I shared. v2 (shared gcode) I printed twice, with the 2nd attempt working without issue.

Phaedrux

Yes, but does sending M106 S255 work reliably? Since that's what your slicer is using to start the fan.

What is the fan configuration in config.g? Perhaps the fan needs a longer blip time to get started.

BlueDust

@Phaedrux
So far the fan has only failed me on 2 prints that I am aware of because the damage was so bad. (out of 30+ prints?)
Even if the fan didn't turn on at the 2nd layer, it should have turned on it was set to 100%.

I don't think I have changed this from default setting since I started to use ideaMaker.

This is an example, but may not have been the layer/fan speed used in the example prints.

Is it worth upgraded to the current beta build on the Deut3, or do you think I could run into other unpredictable problems I will have a hard time with?

BlueDust

Looking at other benchy test prints... I do see at least one where I can confirm I had overheating issues when I shouldn't have. it looks like the fan turned on, but wasn't spinning at 100%. Maybe it accepted a lower speed M106 command, but never received the one for 100%.

I think beta 4.1 is in pretty good shape now. If you want to play it safe wait a day or two for a release candidate build.

BlueDust

@Phaedrux
I just received a distribution board, and two tool boards (to improve IDEX wiring) I know I will need to upgrade. I am really looking forward to being able to update everything easily (including the PanelDue). Wanting to try out that single feature is making it hard for me to not just jump on the Beta builds....
But if it is only a day or two out... I should be able to hold out a little longer.
Thanks!

Phaedrux

Well it's not like it would explode or anything if you were to try it. Maybe just a bit of hassle possibly.
