Changing pt100 to standard thermistor
-
thanks again, so i made the changes you advised straight to the config files incl the config in sys folder on the sd card, loaded back into the machine, then ran pid tune, got this - "Auto tune heater 0 completed in 1489 sec
Use M307 H0 to see the result, or M500 to save the result in config-override.g", but then when i entered M500 via the console it answered - "M500
Warning: No M501 command was executed in config.g". Did i do something wrong? -
i then tried M501, and got this - "M501
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 692C.", feels like im back to square one lol, but the whole hotend, cables and all, are new, and confirmed 24v -

add M501 to the end of your config.g
-
so remove the SD card from the machine and type M501 at the very end of the config file? Can i not send that via the console?

@Atraedes
just edit the file using the web ui -
sorry i dont know how to do that, im still learning the ropes with the duet3d board i have
-
-
Oh wow, I didn't realize you weren't even connected to the web interface yet.

It definitely makes a world of difference.
-
so if i understood correctly, ive gone into system in the web ui, found config.g, opened and typed M501 at the end of the file, and its asking if do i want to reset the board and apply the update? is that correct?
-
no sorry, i probably didnt explain, i am using the web ui, all the time,and running these commands via the console in the web ui, but i thought it was a simple M500 via the console in web ui to save it, and it doesnt
-
Yes you have to edit config.g and add M501 at the end.
As I said, M500 saves SOME settings (like PID tuning or other measured values) to the file config-override.g. And M501 loads that files.

ok thanks, so to try solve these spurious heating faults, run my pid tune, after it shows results then go into system in the web ui, into config.g, M501 at the end of the file, and reset the board and apply the update?

That's not a heater fault. It's a warning.
-
PID tune, send M500 in console, add M501 to config.g. done.
-
awesome thanks, much appreciated

oh my good lord i am losing my mind...I've done everything, seemed fine, heated up hotend to 200c to do a test cube, and "M501
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 612C.", and then "Error: Heating fault on heater 1, temperature excursion exceeded 15.0°C", and it cools down the hotend. I know the first is a warning which i could live with but it then goes into error! Sorry I know i seem like a noob and keep asking questions but i dont get it lol, cables seem fine and ive rechecked everything, do you think there may be another fault elsewhere or is it likely the cables? -
post a picture of the temperature graph.
also do you have the silicone sock on?
-
Yes got a sock on, and thanks for your assistance -
sorry did you want me to rest the hotend and heat again first?
-
reset the hotend even
