Bed heating problems
-
Hi there!have a delta printer running on a duet2 wifi and was running fine until i changed the firmware to a newer one.
This is what i have rigth now: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.6 (2023-07-21) .
The bed heating started to report errors. i commented in this forum and the suggestion was that the bed was very underpowered, so i put a bigger power supply with an ssr for the bed, was heating faster but not enough, so it was reporting errors of heating too slowly. (i runned m303 in several ocations with m500 afterwards).
So, now i took it a step further, and i put a 220v bed heating element, and run m303. When do in so, i put a value of 60 degrees and when reching it it passes up to 61.6 but no more.
everything kind of normal so far, but if i try to heat it up to 60 and when passes up to 61 it gives an error because it passed the target temperature.
I don´t know what to do at this point

@ander It sounds a bit like you have fault detection set too strictly. IIRC, the default is 15 degC. In config.g, you should have a couple of M570 commands, one for the hot end heater (usually H1) and one for the bed heater (usually H0). Check out the "T" value and set it to (say) 5 or 10 degrees. Alternatively, check that your M143 (maximum temperature) is not set too low. You should have a line something like M143 H0 Snnn, make sure "nnn" is set higher than 60.

@ander please post your config.g and config-override.g, as text (and ideally code) rather than pictures.

By the way, every time i power the duet it says "bad model parameters".

@ander Can you send
M98 P"config.g"and post the response from the console?I've updated your post with the files, as it will make it easier to help you.

@deckingman I just changed the "T" parameter and looks like it is working fine no. thanks so much

@ander I think the error is coming from the M307 settings in config-override.g, which is being run because you have M501 in your config.g. Those settings are using the older form and parameters for M307 from RRF 3.1 and earlier.
Try removing the M501 line from config.g, or commenting out with
;at the beginning of the line, and see if you still receive the error.However, it also looks like the delta calibration has been saved there too, following calibration. You may want to copy this back to config.g, or do a new delta calibration.
Also delete or comment out this line in config.g:
M574 F2 S1 P"filamentstop"'filamentstop isn't a valid pin name, and F isn't a valid axis.

Yes, it looks like you had this
M570 H0 P15 T1So the heater fault tolerance was 1 deg C deviation from set point for 15 seconds which is why you got the fault warning.
