Dual extruder PID autotuning!!

Recommended Posts

Hey,

I am using chimera dual extruder in my printer. I am curious about PID settings in marlin. Should there be different PID for both extruders because there are two hotends. I checked PID autotune in repetier with command: M303 E0 S200 C5, it shows me (Kp: 44.40 Ki: 4.43 Kd: 111.31) values. Then just for curiosity, i give following command for 2nd extruder: M303 E1 S200 C5, but it came different (Kp: 22.62 Ki: 1.42 Kd: 90.06). Both extruders are E3d chimera, so it should be same or slight difference. But there was huge difference. Can anyone tell me, what is solution??

Thanks in advance.

Did you wait until both extruders were at room temperature before doing the PID tune on each one?

They are both right next to each other, and share the same cooling block. Running a PID tune on one would probably transfer some heat over to the other if it was still warm/hot. So if you didn't wait until both hot-ends where are room temperature before doing the PID tune, you'd probably get different results due to heat carry-over from the other.

Otherwise, maybe check with E3D - could be different heater cores or thermistors in each hot-end.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
