Describe your issue:

Hello Klipper community,

Im a noivce in a Klipper. Trying to setup klipper for my custom printer. i have a pellet extruder with 3 independent heaters and 3 temperature sensors:

  1. Need to see all temps in a dashboard.
  2. Each heater should has own temperture and Pid parameters.
  3. Can i calibrate PID parameters for each Heaters simulansy
  4. Is there any elegant and typical solution. (example.cfg)

thanks for your reply. I have seen this topic. but there is no any example.cfg. im fully novice. only today just setuped manta board.

as i seen before, i should use something like:
[extruder]

#1st heater settings

[heater_generic extruder_heater_2]

#2nd heater settings

[heater_generic extruder_heater_3]

#3rd heater settings

but im not sure in this construction

I think you could use a Pi Nano (or similar) and name it pellet_mcu. You’d have to add mofset transistors to handle the heater circuits and probably some pull up resistors for the

thermistors. Once built assign the GPIO pins to generic heater function in your printer.cfg.

Perhaps I’m missing something.

Manta has 5 heater pins and 5 temperature pins. I don’t know if it’s worth using a separate device
