Thermistor at 2000c

Phaedrux

Where do you have the heaters and thermistors connected?
What firmware are you running?
What board are you using?
What are the heaters and thermistors?

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

HTTP is enabled on port 80
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?

@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.
