Problem config bed temp
-
Hi everyone
I got troube configuring my heating bed on my printer. When I try to warm up the bed the temperature reaches 40 ° C ( more or less ) and this message appears " Error: Heater 0 fault: temperature rising much more slowly than the expected 1,6°C/sec"
My bed is a keenovo 300 mm x 300 mm. 750 Watt 220 volt connected to a relay SSR-25DA.
The sensors seems to work correctly ( it detects room temperature ).Thanks for your help.

@aribag_33 PID tune your bed using M303

@jay_s_uk
This is what I got
M303
No heater has been tuned yet<LF>ok<LF> -
@aribag_33 see here https://duet3d.dozuki.com/Wiki/Gcode#Section_M303_Run_heater_tuning
I suggest M303 H0 S60 -
@jay_s_uk
I enter the Gcode M303 H0 S60. The temperature increased to 60 ° C and then decreased to room temperature.
Then I activated the bed heating to 60 °C to run a test and it worked.
So thank you a lot.I enter the Gcode M303 to see if it was tuned properly and I got this as an answer.
M303
Heater 0 tuning failed<LF>ok<LF>Will it be a problem in the futur ?
Thank you again

@aribag_33 M303 by itself won't do anything. Thats not how most gcode in RRF works.
If you're on 2.05.1 it should've just heated up and then cooled down and then you save the results using M500 (with M501 at the end of your config) or you copy and paste the outputted M307 into your confg.g
If tuning a bed on RRF3, it will cycle up to 30 times taking any where up to an hour or more to tune.
What version are you on? Check M115 for the version -
@jay_s_uk My version of the firmware is much recent
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-05-19b2<LF>ok<LF>Auto tune heater 0 completed in 153 sec<LF>Use M307 H0 to see the result, or M500 to save the result in config-override.g<LF> -
@aribag_33 yea, upgrade to 3.3.0 and tune again.
upload this zip to the systems tab and let the magic happen https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip -
@jay_s_uk
When I enter M115 I got a version 3.1.1 but when I check the version of the firmware I configured on reprapfirmware config tool it is the 3.3.0 -
@aribag_33 you're definitely running 3.1.1 as the config tool won't know what you're running.
As I say, upgrade using the file above -
@jay_s_uk
How can I upload "Duet2_SDiap32_WiFiEth.bin" ? -
@aribag_33 have you not tried just uploading the complete zip file to the system tab?
you can upload them individually if you wish to the system tab -
@jay_s_uk
I have done nothing yet . I just don't know how to upload this file on the board. My board is duet 3D 2 wifi -

@jay_s_uk
When I try to upload the all zip file I got this after cliking yes
M997 S0:1
Error: M997: in application programming binary " Duet2 combined IAP.bin" not found -
@aribag_33 upload this first. also to the system tab https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2CombinedIAP.bin

@jay_s_uk
Ok I have been able to upload the firmware. I turned on the bed heat and it works !!Thank you again for your time and kindness.
