promega but use duet wifi board

Veti

is this a new development? or are you setting up a new machine?

M305 P1 X501 R2200 ; Define left side extruder PT1000
M305 P2 X502 R2200 ; Define right side extruder PT1000

R2200 is for the duet maestro. but you said you have a duet wifi

patel

@veti
Yes I have duet WiFi

Veti

so delete the R2200

delete but both heater so 2000c

that means you have another M305 command that overwrites the first setting somewhere in your config

@veti
If I use PT1000 sensor I need daughterboard ? Duet WiFi.

No only for PT100 and thermocouples.
