@dc42 @droftarts Any additional thoughts on this? Using the manual process seems to have worked, but I am concerned about not being able to use the semi-automatic method.

@mfs12 I'd vote to just have some simple buttons down the right side. I have 5 tools plus the bed, but I've seen the macro buttons when I've disabled tools in the config. This would be a great option.

@mfs12 This is awesome! Will it pick the correct QOI image if there are two embedded in the gcode?

Last update for the night. I found a 100k resistor and a 220 ohm resistor in my cabinet. I went through and calibrated each temp port following the doc page. Below are the values I got. Now when I jumper the temp port it gives me a reading around 700C. I assume this is ok to proceed. All of the temps now are accurate at least to room temp. If there is anything else that you think I should do before running up the heaters, please let me know.

I removed the SBC from the system and it still does the same thing.

I reverted the firmware to 3.2 and it still does the same thing.

To recap, I've tested this on two different 6hcs, 3.2, 3.3, and 3.4.1 versions of the firmware, with/without the SBC, with/without the 3HC connected. I'm at a loss here ...

Does anyone else calibrate their ADCs?

I just put a duet6hc from another printer I have in this one and it does the exact same thing. The L and H are different, but the 2000 is hopping all over the place. The duet3hc is unplugged so that I can see if the can connection is doing anything. Now I'm going to take it out of SBC mode and see if that changes anything.

@dc42 Here they are as requested. I used a normal pin jumper this time. I noticed that all three are now jumping when jumpered, but S3 is jumping once every 20-30 seconds vs every 4-5 on the others.

@droftarts Can you just use a normal 2 pin jumper on those ports? For some reason I thought it would not fit and therefore created one.

@dc42 Here is a screenshot of running through all the temp sensors associated with thermistors. (S1,S2,S3 all on the 6HC, S0,S4,S5 on the 3HC) I will do the repeat test when I get home later today.

@dc42 Thank you. I'll try running it multiple times in a row when I get home. To be clear, do you just want me to run the H999 phase or or both phases sequentially?

Also to be clear, when it is jumpered, should I expect the value to jump/be erratic? Or should I expect it just to show 2000? On some of ports on my 6hc and all the ports on my 3hc, they all show 2000 when jumpered. Is it possible that it is writing a value during the calibration that is then causing erratic readings when jumpered?

Is there a way to get from the firmware what the calibration value was set to via the M308 H/L command?
