Hi, I'm trying to set up my hotend and heated bed, I can't get the temperature sensors to work, they reading 2000c, I'm using a daughterboard, Please some help

M143 H0 S120 ; set temperature limit for heater 0 to 120C
M307 H0 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M308 S1 P"spi.cs1" Y"rtd-max31865" ; configure sensor 1 as thermocouple via CS pin spi.cs1
M950 H1 C"out0" T1 ; create bed heater output on out0 and map it to sensor 1
M143 H1 S280 ; set temperature limit for heater 1 to 280C
M307 H1 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M140 H1 ; map heated bed to heater 1 -
Which version of the firmware are you using?
-
And which Duet are you using?

M308 S1 P"0.spi.cs1" Y"rtd-max31865" would be correct if its connected to the main board and its a duet 3.
It also depends on which channel you are using on the daughter board. The other channel on the daughter board is cs0.Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

@dc42
I'm using a duet3d mainboard 6HC -
@jay_s_uk on the daughterboard I'm using the rtd1, by the way, I'm using the temp_0 for the sensor
-
@Reaperrhs said in Duet3D Mainboard+Daughter board+PT100:
M308 S3 P"3.spi.cs1" Y" rtd-max31865"
is the space between " and rtd-... correct? (I know, this is like in the documentation in https://duet3d.dozuki.com/Wiki/Connecting_PT100_temperature_sensors )

@JoergS5
thanks for helping, i have one question because I'm learning as I go, for the M308 you replace the existing command or create a new one? -
@Reaperrhs I am unsure whether this is the reason, but if it is, I would replace the line without the space. I could not find the Y parameter in the source code, so I don't know whether it's only a label. But you could simply try.
-
unless your daughterboard is on can board 3 (an expansion board), the command won't work with 3. in front of spi.cs1
-
@jay_s_uk i double-check, there is no space, you can see it in my main post, I copy my configuration, the daughterboard is connected on the mainboard duet3d and my sensor is connected to the rtd1 on the daughterboard
-
Should look like this

@Carlo can you show me the hole config for heaters? just to compare with mine

Here you go

@Carlo thanks, let me see what I'm missing (are you using a daughterboard to??)
-
@Reaperrhs
Yeah I have the PT100 in 0 which is the right hand terminal as you look at it are you 2 wire or 4 wire?
if 2 do you have the jumpers on behind the terminals ? -
@Carlo i have two wires, also the jumpers are in place, the two wires are connected in the right hand of the daughterboard
-
That's 0 channel, 4 connection block only 2 wire in the 2 center terminals ?
-
@Carlo yes, center terminals
