Did you get anywhere with this? I am in exact same boat (1LC+6HC on latest stable RRF 3.4.0)

@jay_s_uk upvoting this - having SBC temperature displayed in DWC along with MCU would be very useful.

Anyone has instructions how to wire up the TFT display to a Duet board (Mini 5+ in particular)?

@jay_s_uk said in Monitoring Duet 6HC drivers:

@leobg no, they only provide 0 (cold), 100 (hot) and 130 (very hot)

Thanks for the clarification!

I am trying to monitor drivers temperature on my 6HC as per https://duet3d.dozuki.com/Wiki/Mounting_and_cooling_the_board with

M308 S3 Y"drivers" A"DRIVERS"

but I get a reading of 0.0 degrees for the "drivers" sensor. Am I doing something wrong?

@dc42 said in [3.4.0b7] Firmware update changes 1LC temp:

@alex-cr and anyone else getting incorrect readings using 3.4.0beta7+2, please post a M122 B# report where # is the tool board number.

Latest I found reference is 7+1, where is 7+2 linked? Another threat? What changed between +1 and +2 btw?

I have upgraded back to b7, (sbc mode), but apt spit an error:

Setting up reprapfirmware (3.4-b7-1) ...

I'll appreciate if someone can throw some insight on what might be wrong with the SBC upgrade mode..

Meanwhile I have manually updated the 6HC and 1LC firmwares (B7-1) from the thread here. Temperature reads normal for me again now. Will give the new firmware a try to see if anything else pops up

edit: here is M121 B121 output:

I can confirm the erratic temperature reading after upgrading to B7 with 1LC v1.1. SBC + 6HC + 1LC. Flashing back to B6 returns thermistor readings to normal. Slice Engineering Hight Temp thermistor (450C).

@martin7404 How did you wire up the super pinda to your toolboard? Are you happy with it? I am considering switching from BL-Touch to superpinda as the BLTouch is often acting up on me and feels not as reliable as magnetic probes

I am running similar (just regular Mosquito), I put together a design (https://www.thingiverse.com/thing:4925085) toolboard attaches between the cooling fan and the extruder, right where EVA cable relief arm mounts. Keeps the toolhead setup as compact and as tucked together as possible. The arm is relocated to the side - original cable relief bracket from EVA can be reused, or the one I added which is smaller since toolboard only requires 4 wires. The bracket has provisioning for a lid, but it felt as unnecessary weight (and would restrict board cooling) and I never ended up finishing it.
