Homedelta.g not sure if it's correct?



  • I created my configs online with RRF config tool.

    But looking at the homedelta.g file doesn't make sense to me

    ; called to home all towers on a delta printer

    G91 ; relative positioning
    G1 S1 X322 Y322 Z322 F1800 ; move all towers to the high end stopping at the endstops (first pass)
    G1 X-5 Y-5 Z-5 F1800 S2 ; go down a few mm
    G1 S1 X10 Y10 Z10 F360 ; move all towers up once more (second pass)
    G1 Z-5 F6000 ; move down a few mm so that the nozzle can be centred
    G90 ; absolute positioning
    G1 X0 Y0 F6000 ; move X+Y to the centre

    looks like its sending the x y past its travel distance
    then it moving the Z-5 that would crash into the build plate
    I always had mine set to z0 at build plate and up from there to enstops
    First time setting up duet so maybe i have to do things different than what i use to

    Thanks Gary

    That looks correct, assuming that your carriages never start more than 322mm below the point at which they trigger the endstop switches.



  • I set it in the RRF for 315 so should i change it to 315,?

  • You don't need to set it to 315 as long as it is larger than 315 (i.e. 322) since it wants to ensure your carriages hit the endstops during homing
