I cant figure out how to lower min temp.
current printer.cfg in extruder is set to:
min_temp: 0
If i chane that value lets say to 150 then i get this error:
MCU ‘mcu’ shutdown: ADC out of range
Is there smomewhere else where i can lower min temp?
klippy (3).log (70.7 KB)
ADC out of range means that you don’t have a thermistor plugged in for temperature readings, OR your connection pin for the thermistor is incorrect, OR you have a break in the wire to the thermistor.
printer is working fine, there is no adc error when i set min temp to 0.
i just got strange pla that prints better at 175c than 185c, so i want to try 160c and klipper wont go lower than 170c
min_extrude_temp: 170
Under [extruder] section
https://www.klipper3d.org/Config_Reference.html?h=thermist#extruder
i am trying to change that value, but i get adc out of range error when i do so.
works fine with min_temp: set to 0, but wont work at 150, 160, 170
this is my extruder in printer.cfg

Post your klippy.log as anyway requested when opening a request for support here.
ok, added klipper log to first post. log after i changed min_temp to 150
For whatever reason, your bed and extruder are reporting a temperature of 0 as the first value and this is causing the shutdown.
I have no idea why, though.
figured it out.
min_temp: turns out to be min temp for not throwing error.
And like NAPCAL wrote i needed “min_extrude_temp:” (thought it was the same as min_temp). Added this line in printer.cfg and everything works.
Have no clue why “min_extrude_temp:” isnt included in default cfg file
