Hi, I have three thermistors for my 3D printer (dual extruder and bed) all are this thermistor type NTC 3950 THERMISTOR 100K.
As shown in this link: http: //smoothieware .org/steinharthart
to get Steinhart Hart coefficients, we send the command: calc_thermistor 25,100000.0,150,1655.0,240,269.0
Then we paste the new values in the M305 S0 command, then save with M500.
1- How to do the same thing for a second hotend, and for a bed?
2- Do I disable these lines to use the new Steinhart Hart coefficients? like this?
#temperature_control.hotend.thermistor
#temperature_control.hotend.beta
Currently my setup is like this for the three heaters (PID is done and saved as well):
temperature_control.hotend.thermistor Honeywell100K # See http ://smoothieware. org/temperaturecontrol#toc5
#temperature_control.hotend.beta 3950 # Or set the beta value
Also do I do PID tuning after setting up Steinhart Hart coefficients?
Thank you.
