Solved Duet 2 Wifi heat bed oddity

[jaymcd0626]

Odd situation that I need help with. Went to Pid tune my heat bed after changing out my Maestro board for duet 2 wifi. Reconfigured. Bed was working but after wanting to calibrate and sending the wrong pid command, I can't seem to get the bed to heat up now. Mistakenly sent an M303 E-1 S60 which immediately came back as complete. Tried the correct command afterward M303 H0 S60 and more get an error that says bed heating up to slowly. If I set a temperature on the heat bed in the dashboard it no longer heats up and I get the same too slowly message . Not sure what I have done or why the heat bed no longer works. Thermistor stays at room temp. ??

Firmware is current beta

I assume you did a power cycle?

Does the temperature reading increase at all when you do a tuning?

[jaymcd0626]

@Phaedrux I did power cycle. No the temp does not move up at all.

Can't imagine if it is possible that the board or bed buggered as everything worked fine before the pid tuning. Nothing physical changed except powering on and off as necessary.

I may try completely replacing the whole firmware ( ie re do the SD card with all new files from scratch)

Don't know if there something that changed in the firmware settings tucked away in another file or something ...???

If you try and warm up the bed thermistor with a hair dryer or something does it register a temperature change?

TRying to determine if it's the bed not heating or the thermistor not reading.

@Phaedrux figured it out. It seems when I did the wrong pid tune command it may have reassigned my heater definition. I may not have noticed because it was in the config override ? I reset the board and redid all the files on my SD card from scratch with the latest firmware. Seems to be working fine now.
