Hi Jason - I took my values from the configuration.h directly off the Marlin source from Creality’s web site, April 2019 release.
Can you double check, I think the correct parameters are:; Heaters
M305 P0 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S150 ; Set temperature limit for heater 0 to 150C
M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1
M143 H1 S275 ; Set temperature limit for heater 1 to 275C
My setting certainly give a correct ambient room temp. on both extruder and bed.
Tony - your comment highlights the problem with the whole of the Duet site - divert the critique of the help site to a web forum that is so full of comments it is almost impossible to discern a reply. And before you jump to conclusions about me, I worked for 35 years in the semi-conductor industry! How about just taking on board the comments and sorting out what are significant problems!
Frankly, most of the instructions on setting up the Duet are ambiguous at best!
As an example, it says read use the G30 S-1 to get height then read from the web interface, so which figure do you read? The one in the Z-axis position box, or, that momentarily appears and is sometimes reported in the g-code console?
Then there is the whole matter of where your probe sits relative to the nozzle and the use of NEGATIVE numbers depending on the position to left/right, front/back.
Then we have the issue of actually enabling bed levelling….. To date I have not found this anywhere in the Duet instructions. Having set up 2 printers using Marlin, this is easily done with the dreaded config header files, Cura code, in comparison!
