Thermistor,PT100, PT1000

jay_s_uk

@auré pt100 are not supported on the toolboard. So it's either a standard thermistor or a pt1000

Auré

@jay_s_uk Hi Jay, thanks I bought a PT100 Daughter Board for the Duet 3 because the NTC 100K is in the silicone of Keenovo and I search a pt1000 for my extruder.

Do you know where to connect the PT100 Daughter Board on the Duet 3 ?

@auré Your bed (NTC 100k) and hot end (Semitec 104NT-4-R025H42G) temperature sensors are both thermistors, though slightly different. Both are supported by Duet and RepRapfirmware.

Use these settings for your bed thermistor:

M308 S0 P"temp0" Y"thermistor" T100000 B3950          ; configure sensor 0 as thermistor on pin temp0

Settings for your hot end:

M308 S1 P"temp1" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin temp1

You can change to a PT100 or PT1000 if you want, see this page for a comparison of temperature sensors: https://duet3d.dozuki.com/Wiki/Temperature_sensors
For a PT100 (which you don't have) you do need a daughterboard.

@auré NTC 100K is a thermistor, NOT a PT100

@droftarts Thank you I test tomorrow If I can, and I tell you the result

Hello, so I have this on my config.g but the toolboard don't see the thermistor

M308 S1 P"121.temp0" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin 121.temp0
M950 H1 C"121.out0" T1 ; create nozzle heater output on 121.out0 and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S280 ; set temperature limit for heater 1 to 280C

I have chek the thermistor with a multimeter and it's ok

Auré

I found this

I change a command line with:

M308 S1 P"121.temp0" Y"thermistor" T100000 B4725 C7.06e-8

But don't work

Phaedrux

Can you send M115 and M115 B121 and confirm that the firmware version on both the mainboard and toolboard match?

M115 B121

Yep:

Console:

@auré you're running out of sync firmware. Try running M997 B121

Auré

@jay_s_uk said in Thermistor,PT100, PT1000:

M997 B121

Ok I send M997 B121:

update tool.jpg

The thermistore not work

I would like stop the fan and I have new error:

Auré

For the fan I found this post

I add F1:

M563 P0 D0 H1 F0 F1 ; define tool 0

And now the fan control work.

~~But not the thermistor.~~

I don't know why but now the thermistor on the toolboard work.....

I have only add F1

jay_s_uk

@auré post your full config and send M115 B121 to confirm 3.2.2 is on the toolboard

Phaedrux

Looks like he is now.

Full config.g would be nice.

Auré

I post tomorrow the config.g thank you for your help good night

can you try increasing the G4 S1 to G4 S4 to give it a bit longer for the toolboard to be ready?

Yes thank you, I told myself that I had to extend the time because when I start the printer with DWC open, sometimes I have error communication of bus, but I forgot.
I think you're right 4 second it's ok.
