extruder sensor transient zero problem
I had a very short duration bad reading from my extruder sensor, which caused a shutdown during a 2 day print.
It may be caused by loose wire, etc., but really I just want to filter out bad readings for now.
Its been suggested I use this:
[temperature_sensor]
type: temp_filter
sample_time: 0.1
min_temp: 180
max_temp: 280
But will this cause more problems than it solves? And where do I put it, because the sensor is deep within RatOS

and in anothjer discussion it was recommened to use [extruder]
smooth_time: 1.0
what do you mean by "sensor is deep within RatOS"?
meaning i cant find a section temperature_sensor in printer.cfg
But further troubleshooting and printer keeps resetting as if there's a broken wire in the hotend sensor, and yet, it reads 3.3volts at the hotend plug, and sensor reads 110kohms when disconnected at that plug. making no sense to me!
okay smooth_time 2.0 was causing that repeated shutdown. i'll try 0.1s
okay looks like sm ooth time in the extruder section may be causing the sutdown - so I took that out and got another sutdown when i closed the lid - very carefully measured at the plug - no voltage this time - time for rewiring back to the board. i wish these wires wouldnt break randomly - so hard to debug !
you can just add that section to printer.cfg. Anything there will override any settings imported before
