SOLVED G30 works autocalibration tilts before it gets a trigger

  • Hi All, figured i'd ask here before i break something (again).

    so after issues with my BLTouch and getting the printer working without a probe i decided to order a smart effector. its all wired up and G30 works great, but when i try to do the delta autocalibraion, it touches the bed and starts tilting the effector before the probe triggers.

    Video of the issue

    the printer is a SeeMeCNC Rostock mk2 with an e3d volcano, smart effector and for now a 3d printed adapter until my aluminum one from maker 713 arrives.

    what am i doing wrong?

    F400 in Your M558 command is too low. Use F1200 as advised at

    If the nozzle is cold, then you should see the green LED flash if you tap upwards on the nozzole with your fingers. Note, you may need to wait about 15 seconds after power up before the electronics has stabilised and the effector reacts with normal sensitivity.

  • that fixed it, thanks,

    i think i copied it the first time without the last 0 on 1200 because i had upped it from 120 to 400 because i thought it was too slow!

    its working great now, thanks
