Thermistor at 2000c
-
@Phaedrux What would be the best way to do this?
-
Alright done, i'll test if that's worked
-
Strange, it's completely changed the way the web interface looks, however it says the firmware version is still the same @Phaedrux
-
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
-
The web interface was updated along with the firmware.
When you send M98 Pconfig.g now do you get any errors?
-
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 365CThis 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.
-
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?
-
@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.
-
@Phaedrux I have pins T3 - T4 wired up, is that correct?
-
I'm not sure what you bought.
To use a pt100 you'll need the pt100 daughter board.
-
Can you post some photos?
-
-
@Phaedrux Hope these help
-
The wiring it a little messy at the moment, please excuse it xD
-
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.
-
This is the thermistors or PT100 I am using, not sure if it helps identify it
-
I believe the E3D PT100s use red wires and the thermistors are blue. But I'm not sure if that's a hard rule, but I think that's generally the case.

You'll need a daughter board to be able to read the PT100.

Alright I can confirm it's a PT100, found the invoice. I will get one ordered asap.
-
Glad we got that sorted out. Once you have the daughterboard installed and connected you'll need to make a change to your temp sensor config to point to the PT100.
M308 S1 P"spi.cs1" Y"rtd-max31865" ; configure sensor 1 as thermocouple via CS pin spi.cs1 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

suppose its still possible they could have shipped the wrong one, to be sure use a multimeter and measure the resistance at room temperature; PT100 should be about 100 ohm, and PT1000 should be about 1000 ohm.
(Techincally PT100 is 100 ohm at 0°C and closer to 110 at room temperature, and 1100 ohm for PT1000)
