First trigger height way off than following



  • Hi there,

    i upgraded my Anycubic Predator (delta printer) with the duet smart effector. I noticed when i calibrate the trigger height the first probe is often much more off than the following probes: (probing at the same XY location!)

    10.2.2021, 12:51:38	M98 P"0:/macros/trigger height"
    Stopped at height -0.206 mm
    10.2.2021, 12:51:35	M98 P"0:/macros/trigger height"
    Stopped at height -0.212 mm
    10.2.2021, 12:51:33	M98 P"0:/macros/trigger height"
    Stopped at height -0.206 mm
    10.2.2021, 12:51:32	M98 P"0:/macros/trigger height"
    Stopped at height -0.199 mm
    10.2.2021, 12:51:29	M98 P"0:/macros/trigger height"
    Stopped at height -0.193 mm
    10.2.2021, 12:51:27	M98 P"0:/macros/trigger height"
    Stopped at height -0.206 mm
    10.2.2021, 12:51:24	M98 P"0:/macros/trigger height"
    Stopped at height -0.193 mm
    

    As i am using 0.9° steppers the difference should only be 0.006 mm. Whats the problem here?

    thank you



  • try this macro.
    it does 10 checks with average. this will give a better overview.

    have you adjusted the sensitivity of the smart effector? maybe its note sensitive enough.



  • no i use the stock smart effector values. I think you forgot the macro or i am blind? 😄
