@T3P3Tony Hi Tony, and thank you for your help. I got it now working well. I think I had an issue previously when I had configured my first sensor to have
M308 S1 P"spi.cs1" Y"rtd-max31865"
instead of having it
M308 S1 P"spi.cs0" Y"rtd-max31865"
based on the naming on the daughter board. But now I got all my three sensors working with two daighter boards.

Hi,
I have read your provided instructions (Temperature connecting PT100) on how to connect Pt100 sensors using temperature board on Duet mainboard 6HC.
Is the possible number to stack daughter boards limited to two? Howabout, is the number of Pt100 sensors that can be connected to the daughter board only one or two? Also, should the temperature board work without having the 100Ohm resistor added to the second connector when measuring the temperature with another connector in use (not for test purposes)?
I am asking this because I would need to connect three Pt100 to my system, and got an impression that the resistor would not be needed and I could use both connectors of the daughter board for measuring temperature ?
BR, Heidi
@droftarts Hi, I am sorry, but I edited my above post after you had marked it solved, based on my comment. However, I noticed another questions related to heater fault detection. Could you answer those still? Thanks in advance. BR, Heidi
@droftarts @gloomyandy @Phaedrux Hi, now we have made your instructed corrections and the above problem with heaters were solved. Thank you for these excellent guidance and support.
I still got one question in mind, related to my earlier problem with my heaters, when I had them wired in an old way and when wiring like now. I had a few cases with the old wiring, when I either did not have the Pt100 temperature sensor connected to the board or my firmware crashed because of my written lines on the configuration file related to the global variables at that time. With the first case I got a heater fault warning and a comment on n/a as the temperature on the web interface, while with the latter case the firmware was not responsive. In both cases, both of my heaters turned on (even without setting-up any input for them), which is not desired.
Was these above events because I had my heaters wired and configured in a wrong manner, and does the above change avoid this risk? I had also my heater fault detection set with M143 as described below but it wasn't able to avoid this unwanted heating:
M143 H1 P0 S300 A0
M143 H2 P0 S180 A0
Also, should I have my allowed lowest temperatures be configured with M143, and not only the maxima? Unfortunately I don't figure it out what does the monitor number mean (P in above commands)? Is it somewhat related to the H term?
I also tried to read about these issues from: https://docs.duet3d.com/en/User_manual/Troubleshooting/Heater_faults, but based on that I assume the firmware should automatically detect at least bad wiring issues?
My firmware is: 3.5.1.
BR, Heidi
@T3P3Tony Hi, and my apologies for the late reply. I repeated my measurements and got a bit more accurate values for the U and V based on those. I now added them in place and neither of the sensors was anymore showing any error, so I think that I might have mixed up with the U and V values. I ensured that the readings now also improved a lot, when using those correct U and V values. So thank you for these parameters for the developers :)!
@gloomyandy Hi, great! Thank you for your excellent reply, I think we will correct our wiring accordingly, but first I will wait my colleague to come back from holiday. When we have tested this, I will let you know if we managed to get rid of the problem.
With best wishes, Heidi
@gloomyandy thank you for your help, I appreciate it. I tried to draw a connection diagram of another of the heaters, and both are connected similarly. Hopefully it is ok, and please, ask further questions if that is unclear and I try to specify it better.
I am not so familiar with electric connection drawings after my school, and my colleague who did the connections is now on vacation.
@gloomyandy Thank you for your reply and notification. Yes, we have configured inverted our cartridge and pressurized air heaters, powered with DC-AC solid state relays (IN: 3-32VDC or 5-24VDC OUT: 24-280VAC), because if they were non-inverted then they would turn ON at start-up when powering ON the Duet 3 6HC board. We have connected the positive wires of the heaters to the out1 and out3, and the negative wires to the GND of board.
When I measured also with a multimeter and saw a short-term -0.040VDC voltage at the start-up of the board, which then dropped.
BR, Heidi
@T3P3Tony and @dc42 Thank you for your clear presentation on how to modify those values. I did my corrections accordingly. However, I noticed that with another of my heaters the U and V values were ok to be added on the configuration file. However, with the another the values were such, that I received an erraneous temperature reading of N/A on the web interface and 2000Cdeg on the user interface panel.
The temperature values for the two Pt100 sensors have the following correction coefficients U and V:
Sensor 1 -> showing reliable results
U-0.00332
V0.066408
Sensor 2 -> showing the error
U-0.01662
V0.332326
What could cause the problem with the another sensor?
BR, Heidi
@Phaedrux Hi, thanks for your help.
I upgraded my firmware and web interface to 3.5.1. and it didn't help with this problem. Also, at start-up each led of those high current outputs (OUT 1 to OUT 3) are turned on. OUT 2 is connected with a servo, and OUT 1 and OUT 3 with by above mentioned heaters 1 and 2. Actually, I noticed from my Panel Due that it gives a warning that my heater 2 is expected to experience overheating problem.
I was thinking, if this problem could require some electrical isolation for example with relays?
I would have also another question related to configuring heaters: As my sensor could detach from the board and initiate error or wrong temperature reading for the heater and trigger unwanted excess heating, I would like to prevent this by determining the minimum temperature that I allow for the heater. Can I program it using M143 command? Like here:
M143 H1 P1 S0 A0 C1 ; Minimum allowed temperature for heater is is 0C degrees, which initiates heater fault and heater truning off
BR; Heidi
@Phaedrux I identified this as the temperature increases (Heater 1: 1.8C Heater 2: 2.1C), which appeared in response to the restart of firmware. These heaters are not similar with each other and the another of my heater gave me a sound that I now for sure that its temperature has increased. Unfortunately, I can't open further details of these on this forum.

Hi, I have found out that when I power ON my Duet 3 Mainboard 6HC or restart the firmware with emergency stop my heaters turn on for a very short time period (1s or so),
I have connected the heaters to OUT1 and OUT3 of the board and have set-up a BtnCmd testing panel, in which I monitor also the heater PWM outputs with the temperature. At least based on that panel I don't see any activation of the OUT1 and OUT3 PWM outputs simultaneously, but of course I can't monitor this during the restart.
I have aimed to avoid this by specifying in the config. file that tools are not ON, by default but this does not help, but still occurs. Below is the code that I have used:
M568 P0 R0 S0 A0
What could cause this issue? Does there occur some other electric spike on my heaters that isn't caused by Duet 6HC board turning ON, or is this still some configuration problem?
BR, Heidi
@droftarts Hi Ian, I modified my codes so that they would be easy to test now. So it would be great, if you could find out the cause why I can't abort on-going macro with those. I haven't figured it out yet.
BR, Heidi
@droftarts Hi Ian, yes, I understand completely and definitely want to do as it is easier for you. And thank you, now I got the idea that I just copy-paste inside those marks, simple :). Now the code is as it is as I have used it with Duet.
@droftarts Hi, thanks, I modified my code now. I don't know if those > and >> were necessary to see the indentations, but I added them anyway.
@droftarts Hi, I have been testing the above ideas further using a macro, in which I have a repeatable beep-sound, which I should be possible to end if the stop macro is activated.
The code, consisting of 5 beep sounds, is as written below:
if !exists(global.abortMacro)
global abortMacro = false ;
var Toisto = 0
;loop
while var.Toisto < 5
echo global.abortMacro
if global.abortMacro = false
echo global.abortMacro
M300
G4 S2
set var.Toisto = var.Toisto +1 ;iterations
echo var.Toisto
echo global.abortMacro
if global.abortMacro = true
abort "Aborted"
Then, I have Abort_activation macro, in which I change the global variable abortMacro to true:
set global.abortMacro = true
However, it seems that my Abort_activation macro does not have an effect on the ongoing beep-sound macro, when it is running. Like the beep-sound macro would check the state of the abortMacro global variable? However, my Abort_Activation macro works when used without the running beep-sound macro, as I have seen from the console.
Would I need to have some kind of break in my while loop to be able to see the changes in the global variable state during the repeatable process of beep sounds?
BR; Heidi
@droftarts Thank you for your edit. I tested my files and the macro file, which I am running and am willing to abort, does still not respond to another macro (called Abort X), in which I activate the global variable of the configuration file with global.abortX=true. I don't get any warnings, still. As a result, the macro is still running.
Have I understood correctly that it is possible to abort the running macro (called X), just by including inside of it the commands
if global.abortX
abort"0:macros/X"
BR; Heidi
@dc42
Please, find below the above macros with indentations:
In config.g
global abortX=false
In the macro file, named X, I should be able to abort when needed:
set global.abortX=false
M42 P6 S255 ; output is generated
G4 S10
if global.abortX
abort"0:macros/X"
In the Abort X-macro activation macro I have:
set global.abortX=true
@dc42 Thank you for your advise and my apologies for the delayed response.
I need to allow canceling a few different macros, which I could name as X, Y, and Z. I tested this with single, but for some reason didn't get the abort to work but the macro, which I was intended to abort with another macro but it the executed macro did not stop working. Here is how I modified your above code:
In config.g
global abortX=false
In the macro, which I should be able to abort when needed:
set global.abortX=false
M42 P6 S255 ; output is generated
if global.abortX
abort"0:macros/X"
In the abort macro I have:
set global.abortX=true
Why does not my abort macro affect the macro that I would like to abort?
@dc42 @T3P3Tony @Phaedrux Thank you all for your help.
I had tried to modify the formula that was given for the M308, which Phaedrux instructed but I didn't understand it sufficiently to get it working. However, based on instructions on T3P3Tony I now got the point better and am now able to make the required modifications.
I would like to double check, that dc42 meant that my 3.5.0-rc.3 firmware version is not the latest release? I checked the version from https://github.com/Duet3D/RepRapFirmware/releases and it seems that this should be the latest?
