@RogerL Post your config.g file so we can see exactly what it is you are doing.

@oliof It's only supported using a custom adapter (not provided by Duet3D): https://forum.duet3d.com/topic/23034/12864-display-st7920-on-duet-3-mini5/14?_=1727247965422 I use one of those in my Ender 3 Pro as well.

@Phaedrux
No this only happens when a message on printer display is shown (see first post).
I searched the forum and found https://forum.duet3d.com/topic/36277/many-problems-with-3-5-2/18?_=1727095288513
for me it is the same issue.

I'd suggest re-tuning it from dead cold using M303 T0 S230 to tune it as a tool rather than just the heater. This will incorporate the cooling fan a well.

@RockB said in Heater Fault - Temperature raising slowly:

;M307 H2 R2.43 D5.5 E1.35 K0.56 B0 ; configure model of heater #2

Was this your previous tuning results?

@dc42 Sorry for the missing details!
Yes, it's a Duet2 and i'd like to use exp.heater5 on the expansion connector.
I will design the "driver" according to your suggestions.

I was aware that i need to invert the output. But thanks anyway.

@droftarts thanks

@droftarts No, the PC does not detect the Duet at all, I do not get any messages about drawing too much power.
many thanks
Lachlan

@misterjtc thank you, I couldn't wait for the answer so I checked that out myself and it worked)
And thanks for the config, I think I'll need that after I buy the cable to power the bed)
(because for some reason FYSETC Big Dipper clone of Duet 3 mini 5+ has separate bed power input)

@misterjtc I've been trying to reproduce it but so far without success with a Mini 5+, RPi 5, and v3.5.2. There is no limit for connection retries.

How do you keep the Duet powered off? If it's connected via the shipped ribbon cable, I'd expect it to be powered from the Pi anyway (5V). To keep my board "off", I wrapped a cable tie around the board which pushes the reset button continously. Can you confirm the spidev buffer size is set to 8192 bytes? If it's too low, DSF and RRF may be unable to exchange data. If you have a spare microSD card, please try one of the official DuetPi builds. They are based on the official RPi OS, too. If it happens with DuetPi as well, try to log on to your Pi via SSH and check the output of journalctl -u duetcontrolserver -ef. This is what my output looked like after 13mins of the board being unavailable: Sep 19 11:35:51 duet3 DuetControlServer[726]: [warn] Lost connection to Duet (Timeout while waiting for transfer ready pin) Sep 19 11:48:32 duet3 DuetControlServer[726]: [info] Connection to Duet established

After that, config.g was executed as expected.

@misterjtc said in Screen Blanking and Pi Camera not working on 3.52:

I suspect the reason for no screen blanking is potentially because of using kiosk mode

DSF ships its own launch-dwc script which basically does nothing else than launching Chromium. It does not start it in kiosk mode.

@misterjtc said in Screen Blanking and Pi Camera not working on 3.52:

but I was able to get it working with the Spyglass plugin. This leads me to belive there is some issue with the motion plugin.

Motion requires the libcamerify wrapper in order to work with RPi cameras but we've had reports of that wrapper hanging up after a while, so we recommend usng Spyglass for RPi cameras instead. That one uses the native RPi camera interface. Motion is fine for USB cams, though.

@jay_s_uk Ohhhh ok! Thank you very much. Due several circumstances i couldn't do anything with 3D Printers for 6 years. But i realized that I've forgotten a lot, to be honest. And now I'm so insecure and doubtful about everything. Thank you! 👍 😉

Aaaaand it worked! Thank you! sorry for not reading the instruction properly from the beginning. xD

@dc42 That is an even cleaner solution. Thanks for the suggestion.

Best regards
Oskar

@Zseven have you seen https://docs.duet3d.com/en/User_manual/Machine_configuration/CAN_connection#mainboard-used-as-expansion-board ?

@dc42 @droftarts
Now the tedious work to get config edited and I/Os wired, assuming I am going to stumble on sopme issues, so questions may arise.

Cheers
Bengt

Hey @droftarts and @dc42 - FYI this issue is fixed in the alpha firmware linked by Andy Everitt in the github issue for this bug: https://github.com/Duet3D/RepRapFirmware/issues/1039 Thanks again for all your help on this!

droftarts created this issue in Duet3D/RepRapFirmware closed [Bug]: Motor brake reports error when configured on mainboard used as expansion board #1039

@dc42 Thanks for the idea. So I decided to use io3.out. I have this in my config.g

M452 C"io3.out" F500 R255 S1 ; configure Laser port
M563 P1 S"Laser"

is this correct? I don't see anything showing in DWC for the laser, am I missing something, are there any other files I would need to configure outside of config.g?
