We currently have a self contained high voltage bed heater that uses a TCN4 that controls and displays bed temperature and does not connect to our duet wifi board. We had originally drilled a thermistor into the side of the bed and hooked to the Bed Temp input on the duet wifi board to be able to get some visual on the computer that the bed was on and working, but the temperature is not close to being correct.
The TCN4 uses a PT100 to read the bed temperature. We hoped we could connect to this at the TCN4 input and hook to the Bed Temp input of the duet wifi board and get an accurate reading, but we are getting around 540C reading when off and the ambient is around 23C
After some research I see that the PT100 needs an adapter board like we have on our two extruder PT100's but not sure how one would plug into the Bed Temp location, if this is even the issue, or maybe just a setting, any help would be much appreciated.

We are running Duet WiFi 1.02 or later + DueX5 version 2.05 (2019-12-13b1)

M305 P0 T100000 ; Set thermistor + ADC parameters for bed heat

Sorry, I tried to upload some pictures of what we had but keep getting an error !

@phaedrux It say's " Paused "
When I resume it just trys to run the xy motors and then runs the
z down.
I will shut down the machine and restart at that print height and see
if it still happens.

Ok I got this fault about half way through a 80 hour print. X and Y motors try
to run but don't move. Just a small vibration like they are trying to move.
z and extruder motors run when print is paused. Right now it is just hovering
off the top of the print.
Not sure how to go forward

Thanks for any help -

@phaedrux Thank You

@dc42 Thank you

M906 reads that the duet wifi is done in steps of 100ma. If our motors are .9a ,would it be M906 X, Y, Z, E800:800
and 900 would be 100%

@diy-o-sphere
thanks I had that, what I found and was looing for was the m569 needed to assign each to its own drive

We are moving our Z motors from Za and Zb of the duet wifi to the Drive 6, 7, 8, 9 of the duex 5 so they are independently driven instead of wired parallel left and right.
What code do I need to look for and change so the system knows I moved them?

Do you know at what temperature they will give the warning? and without a thermistor is this something the board is reading through the motor wires or is it the connection at the board that is getting hot?

We keep getting a warning over and over
Warning High Temperature reported by driver(s) 2
But we are not showing any faults and temperatures are good
Is driver(s) 2, heater 2? or is this not the driver 2 but 2 drivers? and if so is there way to find out which drivers and how to fix the warning?
MCU is running at 36C
