Hotend and Heated bed reading 2000deg celcius and fault

@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.

droftarts

@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

droftarts

@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

NEVER LUCKY

alright! its all fine the wiring was wrong... so dumb of me!

the bed heater is still fault for rising slowly though.

droftarts

@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 e0temp

T100000 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 S1.00

While 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 S200

Run 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 H0 or M307 H1 from the console.

Ian

NEVER LUCKY

thanks for the tips!!
so now im doing the tuning by sending the commands from above, ill do it 3 times as you said, but where exactly must i add M501 in config.g ?
at the last line of ;Heaters or the last line of config.g ?

droftarts

@NEVER-LUCKY
Either add M501 to the end of config.g so they load from config-override.g, or copy the heater settings (M308 for bed and hot end) to config.g (from config_override.g to config.g)

Ian

NEVER LUCKY

right. and should i send M500 after i tune the bed and then tune the hotend and send M500 again? Or can i tune the bed and hotend both 3 times and afterwards sent M500 once ?

Phaedrux

@NEVER-LUCKY Send M500 after each. I'm not sure if the tunes values are applied immediately after tuning, or if they need to be saved and loaded by a reboot. Actually, you don't even have to reboot. Save with M500 which saves the values to config-override.g and then send M501, which loads config-override.g.

For what it's worth I've only ever run the tuning once. IF you do run it multiple times, don't forget to let it reach room temp before starting again.

NEVER LUCKY

for some reason my hotend fans stopped spinning. should i tune the hotend without fans?
im not sure what the problem is, the two fans stopped spinning last night, but when i click on TestFans, they do just fine and start spinning and after the test they go off.

Phaedrux

@NEVER-LUCKY said in Hotend and Heated bed reading 2000deg celcius and fault:

No.

What do you have in your config.g for fans? How are the fans wired?

Phaedrux

@NEVER-LUCKY said in Hotend and Heated bed reading 2000deg celcius and fault:

TestFans,

Test fans sounds like a factory test macro. Do not use it.

Does the hotend fan spin briefly at power on?

NEVER LUCKY

They are wired fine because TestFans Macro runs perfectly but after that they turn off completely and there is no way to turn even on of the two on. Im using an alwaysOn fan aswell to cool the drivers and that is running just fine. only the two hotend fans are not spinning.

Ok, I'm guessing you didn't choose any fans when running the configurator.

How do you have the fans connected?

You said that when you ran TESTFANS the fans would spin?
Can you post the contents of that macro?
