RRF and Heaters – Duet 2 WIFI 3.1.1

Tried M303

Got

M303 H1 S265
Error: M303: heater 1 reported error 'sensor open circuit' at start of auto tuning

That means you have issues with your thermistor.
What is showing in DWC?

Both my thermistors where working perfectly before the update and I didn’t touched the wirings so…..

By DWC you mean this? (Sorry I'm just an end user)

Can't see anything wrong with what you have in your config. (assuming you made the changes to the M308 we discussed earlier)
If you send

M98 P"config.g"

What comes up?

M98 P"config.g"
HTTP is enabled on port 80

MJCT

Manually I did this

; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B3950 C570.5 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S110 ; set temperature limit for heater 0 to 110C
M308 S1 P"e0temp" Y"thermistor" T100000 B4092 C202.3 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M140 H1 ;
M143 H1 S290 ;

No luck

@jay_s_uk said in RRF and Heaters – Duet 2 WIFI 3.1.1:

yes you can use those values

no you can not. they will lead to the result you are seeing.

@MJCT

delete C570.5 and C202.3

MJCT

@Veti What do I put in place?

Veti

@MJCT

nothing

MJCT

@Veti like this?

Veti

@MJCT
yes

MJCT

@Veti Yes!!!!

Now, two questions

Why didn’t the RRF created a M140 and M143 codes for the H1 (I did it manually)?
Can (should) I run a new M307 for each thermistors? If so, do I need to erase 0:/sys/config-override.g or should I just leave it alone?

jay_s_uk

@MJCT run M303 for each heater.
Once complete run M500 and it will over write the values in config-override

i think there is a bug regarding this in the configurator

Can (should) I run a new M307 for each thermistors?

yes its required on rrf3 (at least for the bed)

If so, do I need to erase 0:/sys/config-override.g or should I just leave it alone?

currently its not used because there is not M501 in your config.g
this also means you can not save values with M500

MJCT

@Veti Sorry , I meant to say M303 not M307

Veti

@MJCT

yes you run M303 and put the values into the config with M307.
i understood what you meant.

MJCT

@Veti After both tests and M500's got this

do I need to add any M501 at config-override or at config.g?

at the end of config.g

MJCT

@Veti Just like this?
