PID tuning incorrect
Closed, ResolvedPublic


I dont think there was a PID tuning done with the angelfish and finch toolheads. I ran a couple on my desk printer and got P15.02 I0.86 D65.21. It seems to work well. Prior to this all testing in R&D was with old PID settings but for some reason we are now seeing failure outside of R&D. Can we add these new PID values to the FW?

@west: The current FW has indeed been tuned for these toolheads:

#if defined(LULZBOT_E3D_Titan_Aero)
    // LulzBot V6 block with E3D Titan Aero
    #define LULZBOT_DEFAULT_Kp 19.83
    #define LULZBOT_DEFAULT_Ki  1.53
    #define LULZBOT_DEFAULT_Kd 64.16
#endif /* LULZBOT_E3D_Titan_Aero */

The values don't appear to be that different from the one's your provided, but I can certainly update them to be the ones you found.

Marlin .70 will have the new values.
