Hotend and Heated bed reading 2000deg celcius and fault
-
hi , I have an issue with heating the bed and hotend on a duet2 maestro. On the web control it says that they are both 2000 degrees celcius, but they aren't even heated a bit when i touch it. Heater 1 and Heater 0 are both fault and every time i reset it, nothing changes and they go back to being fault.
I measured the resistance of both of the thermistors at room temperature.
Hotend: original E3D Thermistor Cartridge
115kOhmsBed thermistor: 100K EPCOS B57540G0104J
120kOhmsThe connection and crimps are fine.
Both termistors i have soldered to some wire to extend the length.I get error messages in console after resetting , and also when i click on TestHeaters in Macros in the web control.
I might have chosen the wrong options when creating the configuration, so i will include screenshots of the files.

It looks like you have the wrong names and I can not see where you have defined M950
Here is my config, hope that helps; Thermistors and heaters
M308 S0 P"bed_temp" Y"thermistor" T100000 B3950 H3 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bed_heat" T0 ; create bed heater output on bedheat and map it to sensor 0
M143 H0 S70 ; set temperature limit for heater 0 to 70C

It's still not working. still same problems.

can you post your complete config.g
What firmware are you using?
Where have you connected the heaters and sensors on the board? -

You did not change the P parameter, it should be:-
M308 S0 P"bed_temp"
M308 S1 P"e0_temp" -
i changed it now and it still isnt doing it

Why do you have M303 commands in config.g? They don't belong there! They are for manual use only.
-
i removed it and still no results. same problem and for some reason the hotend fan stopped spinning last night.
-
@NEVER-LUCKY Please send M115 to the Duet and post the reply. Your config.g is set up for RepRapFirmware 3, but I think your Duet is running RepRapFirmware 2.

im really lost here. what should i do?
-
@NEVER-LUCKY Yes, you're using a config.g file for RRF3, but your board has RRF 2.05.1. The first line of your config.g is
; Configuration file for Duet Maestro (firmware version 3)So the config tool does tell you what firmware version it's for.Is this a new board, or was it working before? If this is a new install, either:
- If you have the config.json file you used to generate your current config.g, go to the RRF config tool and load it. Then, on the 'General' tab, change the firmware version from '3.0 or later' to '2.03 to 2.05'. Then go through and check that it's set up correctly, export config.g, and try that.
Or
- Update your Maestro to RepRapFirmware 3 (which is going to be the future of the firmware) and sort out config.g issues there.
If it was working before, revert to the config.g you were using.

RRF config tool
oh nice. its doing fine now.
however im getting new errors: the hotend doesnt heat up and is at -273,1 and the bed gets the error for heating up slowly.
-
@NEVER-LUCKY Which did you do, update to RRF 3, or generate new config.g? If new config.g, post it. Please post the whole config.g, as text, in the 'code' tags, using </> from the formatting bar.
-273 means that the thermistor is not connected. Probably you have defined it for the wrong pins.

i updated the firmware to 3.0.

i didnt change a thing in the config and didnt generate a new one. only the RRF is 3.0 now

@NEVER-LUCKY Okay. Hot end thermistor should be on e0temp, the right-hand two-pin connection here:
If it is, can you test the wiring with a multimeter? If not, try swapping bed and hot end thermistors connections, see if you get a reading for the hot end thermistor on the bed.
Ian
-
alright! its all fine the wiring was wrong... so dumb of me!
the bed heater is still fault for rising slowly though.
-
@NEVER-LUCKY You'll need to tune the bed with M303. RRF3 doesn't assume that any heater is a bed, so it just thinks something is wrong.
First, you need to get your temperature sensors reporting accurately. You're using:
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0tempT100000 B4138 is the default thermistor setting, for a Honeywell 135-104QAD-J01 thermistor that shipped with hot ends from RepRapPro, who have been out of business for 4 years! So I doubt you have the correct thermistor settings, and likely the temperature your heaters are reporting is not accurate. All 100k ohm thermistors have a resistance of 100k ohms at 25C, and will be fairly accurate at room temperature, but they report very differently as they get hotter. So please check what thermistors you have in your bed and hot end, and set them correctly, then you have a chance of accurately setting extrusion temperature.
Then, your heater settings. For full details see: https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control
Your heater settings are at the default. It looks like you haven't tuned your heaters THEN sent M500 (to store them to config-override.g). Alternatively you can copy the heater tuning to config.g. This hasn't been done, as the heater profiles in your config.g are still:
M307 H0 B0 S1.00 M307 H1 B0 S1.00While the hot end will probably heat up, the temperature control won't be smooth. So, tune heaters with something like:
M303 H0 S60 M303 H1 S200Run them each a number of times (usually three times will do), but wait for the heater to be at room temperature before doing it again. Once the results converge, send M500 to save them to config-override.g
Then either add M501 to the end of config.g so they load from config-override.g, or copy the heater settings to config.g
You can check the current heater settings by sending
M307 H0orM307 H1from the console.Ian
