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

; Heaters

M305 P1 X200
M308 S3 P"3.spi.cs1" Y" rtd-max31865" ; configure sensor 0 as thermocouple via CS pin spi.cs0
M950 H0 C"out1" T0 ; create nozzle heater output on out1 and map it to sensor 0
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?

dc42 · 28 May 2020, 05:58

And which Duet are you using?

jay_s_uk · 28 May 2020, 05:59

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.

@dc42
I'm using a duet3d mainboard 6HC

Reaperrhs · 28 May 2020, 15:42

@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 )

Reaperrhs · 28 May 2020, 16:14

@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?

JoergS5 · 28 May 2020, 16:16

@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.

jay_s_uk · 28 May 2020, 16:18

unless your daughterboard is on can board 3 (an expansion board), the command won't work with 3. in front of spi.cs1

Reaperrhs · 28 May 2020, 16:22

@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

Carlo · 28 May 2020, 16:23

Should look like this
M308 S1 P"spi.cs1" Y"rtd-max31865"
M950 H1 C"out1" T1

Working on my duet 3 mainboard

Reaperrhs · 28 May 2020, 16:30

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

Carlo · 28 May 2020, 16:42

@Reaperrhs

Here you go
Ignore the bold as that was a temp test with thermistor
Eveything else is printing really well now on my setup

@Carlo thanks, let me see what I'm missing (are you using a daughterboard to??)

Carlo · 28 May 2020, 16:48

@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 ?

Reaperrhs · 28 May 2020, 16:53

@Carlo i have two wires, also the jumpers are in place, the two wires are connected in the right hand of the daughterboard

Carlo · 28 May 2020, 16:54

@Reaperrhs

That's 0 channel, 4 connection block only 2 wire in the 2 center terminals ?

Reaperrhs · 28 May 2020, 16:55

@Carlo yes, center terminals
