Error: Heater 1 fault: exceeded allowed, when cold booting
-
Every time I star my printer, I get this message:
"Event Notification"
"Heater 1 fault: exceeded allowed temperature excursion: target 220.0°C actual 53.0°C"After I close the message and reset the nozzle heater everything is as expected.

The M307 values in your config.g are quite different from those in config-override.g.
when did you last tune the heaters? And how did you save the results?
-
@Phaedrux
Tuned them them with M303 a couple of weeks ago and M500 to save -
@TomasL said in Error: Heater 1 fault: exceeded allowed, when cold booting:
Every time I star my printer, I get this message:
"Event Notification"
"Heater 1 fault: exceeded allowed temperature excursion: target 220.0°C actual 53.0°C"Do you mean when you start a print, or when the printer powers up?
-
@Phaedrux Turned on, or reset
-
What does your temp graph actually show?
-
@Phaedrux 53
-
I'm still confused. Is this immediately when you turn the printer on, or after you have set a temperature?
Can you take a picture of the temp graph?
-
@Phaedrux When I switch Power on, or press the emergency stop and it reboots.
I might found the problem, last entries in the config override is intended to put the heaters at some middle temperature, in order to speed up the print.
I.E sett both extruder and bed at a standby temperature, however when I removed those lines the message dissapeared.
Obviously something is wrong with those linesAs I understand it
M568 P0 R200 S220 A1 M140 H0 S70 R55 M144M568 sets the extruder active and standby temperatures, and switches the extruder heater to
standby
M140 sets the bed heater standby and active temperatures.
M144 sets the bed heater to standby.So obviously there must be something wrong with the M568-line
-
@TomasL It's best not to manually edit the config-override.g. It's a firmware-generated file. Put any commands like that in config.g.
Order dependency
In RRF3 a M140 command with H parameter (other than H-1) must come after the M950 command that creates that heater, and before any M143 command that sets a temperature limit for that heater.
You don't need the H parameter in M140, you've already defined the bed. Use P if you have more than one bed (which you don't).
Edit: it's generally not a good idea to have heaters or motors turning on automatically at start up. If you have a fault, or you have taken something apart, and the mainboard resets, you'll get power turned on when you don't want it to, automatically.

@droftarts
Yes I have realized that regarding config override.
However the issue with the message regarding the extruder heater is still there.
The bed heater did not produce any errors.
