Thermistor at 2000c

[Bewaren]

Duet 2 Ethernet I believe, was a while since I bought it and only just had chance to use it.

Running RepRap 3.1.1

Bed is wired into a SSR and the thermistor too the thermistor bed pins

Using a 10" 400w Keenovo heater pad with a NTC 100k thermistor (Beta 25/50 3950k)

If you send M98 Pconfig.g in the gcode console do you get any error messages?
If you send M115 does it report that you are actually using 3.1.1?

[Bewaren]

@Phaedrux When I send M115 I get

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.03 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2019-06-13b2

When sending M98 Pconfig.g I get

FTP is enabled on port 21
TELNET is enabled on port 23

@Bewaren said in Thermistor at 2000c:

FIRMWARE_VERSION: 2.03

There we go. You've not actually updated to 3.1.1. You'll need to update to 3.0 first do to some required IAP files, and then to 3.1.1.

[Bewaren]

@Phaedrux What would be the best way to do this?

[Bewaren]

Alright done, i'll test if that's worked

[Bewaren]

Strange, it's completely changed the way the web interface looks, however it says the firmware version is still the same @Phaedrux

[Bewaren]

I've managed to get the firmware updated, just had to reinstall it. However the thermistors now show a temperature of '-273.1 C'. @Phaedrux

[Phaedrux]

The web interface was updated along with the firmware.

When you send M98 Pconfig.g now do you get any errors?

[Bewaren]

@Phaedrux

HTTP is enabled on port 80
FTP is enabled on port 21
TELNET is enabled on port 23
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C

This is what I am getting now, I am also struggling with the smart effector wiring for the thermistor, I am using a PT100 Thermistor, 2 pins but I am trying to figure out which pins I need to connect it too.

[Phaedrux]

If you're using a PT100 your config is incorrect.

M308 S1 P"e0temp" Y"thermistor" T100000 B4138      ; 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

This is for a thermistor. In the configurator you'd need to choose which channel you have the PT100 connected to.

Do you have the PT100 daughter board?

[Bewaren]

@Phaedrux I do not no, I am using the thermistor provided with the E3D Hotend for the smart effector, I believe it is a PT100, correct? It was a while back since I bought it.

[Bewaren]

@Phaedrux I have pins T3 - T4 wired up, is that correct?

[Phaedrux]

I'm not sure what you bought.

To use a pt100 you'll need the pt100 daughter board.

[Phaedrux]

Can you post some photos?

[Bewaren]

@Phaedrux

[Bewaren]

@Phaedrux Hope these help

[Bewaren]

The wiring it a little messy at the moment, please excuse it xD

[Phaedrux]

Well we need to verify what sensor you are actually using. Is it a thermistor or PT100. If it's a PT100 you will need the daughter board before you can use it.

[Bewaren]

@Phaedrux

This is the thermistors or PT100 I am using, not sure if it helps identify it
