Using multiple heaters with Thermocouple Daughterboard (J Type)
-
Hi, I'm using a Duet 3 Mini 5+ and I'm connecting 2 J-type thermocouples to the Thermocouple Daughterboard (thermocouple-max31856) and I'm running into a few issues:
- heaters aren't behaving as they should:
- not heating up at the same time (Heater 1 displaying 'fault' when Heater 2 displays 'active' and vice versa)
- overshooting allowed temperature on Heater 2 only (Heater 1 seems to follow the set temperature max correctly)
- We don't use or define Heater 0, however, console error messages often display: 'Heater 0 fault'
Could someone have a look at the config.g file for any syntax or logic errors that may be causing the above issues?
Additionally, if there are any hardware/wiring considerations which may also be problematic. I've confirmed that the wiring polarity is correct. For example, Heater 1 is reading out expected temperatures, but only when it is the only active heater.

@ozgunkilicafsar did things work normally using thermistors, before you got the daughterboard?
here is my heater config if it helps. but i use thermistors for my heaters, but i do use the thermocouple daughterboard but i dont link them to any heaters for my setup.

not heating up at the same time (Heater 1 displaying 'fault' when Heater 2 displays 'active' and vice versa)
What happens to the temperature of one when the other is active? To me it sounds like there may be interference between the two.
It looks like you haven't tuned either heater; they are both set to M307 H1 (or H2) B0 S1.00, which is the default. RRF needs an accurate model of how the heater behaves, so it knows if there is a heater problem. For tuning, see https://docs.duet3d.com/en/How_to_guides/Commissioning#h-7-tune-heaters
Also see https://docs.duet3d.com/en/User_manual/Troubleshooting/Heater_faultsovershooting allowed temperature on Heater 2 only (Heater 1 seems to follow the set temperature max correctly)
By how much does heater 2 overshoot? If the excursion is less than 5 seconds, or for less than 15 seconds (these are set by M570), no heater fault will be raised. Again, tuning the heaters should help.
We don't use or define Heater 0, however, console error messages often display: 'Heater 0 fault'
Send
M950 H0to see how that heater is defined. It may be defined by default, though I don't think it is. What version of RRF are you using? Send M115 and post reply. Also sendM98 p"config.g"and post the response. It may be something is trying to turn heater 0 on, and you get a fault because it is not found.Ian

@droftarts said in Using multiple heaters with Thermocouple Daughterboard (J Type):
Thank you very much for the detailed response @droftarts, I definitely did not tune the heaters so I'll get on with that.
Before that, to rule out H0 errors, I followed your suggestions and sent M950 H0 and got the message below, indicating that it's not defined (since I don't use heater 0):
Also sent M98 p"config.g" and the response is as below:
Is there a way to eliminate getting these error messages?
After resolving this, I'll go forward with heater tuning for H1 and H2.

@ozgunkilicafsar Can you post what firmware version you are using? Send M115 and post reply. Also check that you are using the same version of DWC as RRF.
Ian

@droftarts Totally right, I'm using DWC 3.4.0 while RRF 3.3. I'll update the RRF to match DWC and check again. Thanks a lot!
