Switch to Pt-100
-
So I changed to a Pt-100 for high temp printing. I can manually enter "M305 P1 X200" and the control will display the correct temp. I would like to make this change permanent. Below is the line from the config.g in settings. I tried M305 P1 X200 B4138 R4700 with no luck. Can someone tell me how to fix this?
M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1
I would also like to know how to adjust the temp limits for the bed and extruder. I plan to print PEKK so I need to adjust up to 140C on the bed temp and 360C on the extruder.
There is no box!

@carlbosson said in Switch to Pt-100:
M305 P1 X200
just replace the line with exactly that. no B or R value
for the max value adjust these lines
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M143 H1 S280 ; set temperature limit for heater 1 to 280C -
Sorry adding just "M305 P1 X200" Seems to have done the trick.

@carlbosson As you have discovered, when using a PT100 you don't need the B and R parameters. Simply replace your existing M305 line with M305 P1 X200.
The maximum temperature limits are set using M143 https://duet3d.dozuki.com/Wiki/Gcode#Section_M143_Maximum_heater_temperature
Edit - we must have been typing at the same time so I missed you last post.

@veti Thank you, I missed adding the adjustment after S. All seems to be working now! Thanks
