    Hi,
    this is a very beginner question iam sure.
    Iam trying to configure the homing action on my delta printer. I have configured the files following the wiki, now i want to trigger the homing action and see if it works, but how ?
    In the Machine control tab, i click the "home all" button, but then nothing happens. I can hear the motors turning ON, but nothing move…

      I tried to put the code into a macro:

      ; Homing file for RepRapFirmware on Mini Kossel
      G91 ; use relative positioning
      ;******* Change F250 in the following line to F2500 when you are finished commissioning
      ;******* Change 320 in the following to a higher value if your Kossel has taller towers
      G1 S1 X320 Y320 Z320 F1000 ; move all carriages up 320mm, stopping at the endstops
      G1 S2 X-3 Y-3 Z-3 ; move all carriages down 3mm
      G1 S1 X6 Y6 Z6 F250 ; move carriages slowly up 6mm, stopping at the endstops
      G1 Z-5 F2000 ; down a few mm so that we can centre the head
      G90 ; back to absolute positioning
      G1 X0 Y0 F2000 ; centre the head and set a reasonable feed rate

      But it doesnt work either…

        Actually testing a bit further. When i click "home all" a first time, the motors truns on, then i click a second time, the 3 motors are moving down a little.
        The "home all" doesnt execute all the g-code from the homedelta file ?
        it doesnt seem to execute: G1 S1 X320 Y320 Z320 F1000
        Going all the way up.

          In config.g, when i change this line M574 X2 Y2 Z2 S1 to M574 X2 Y2 Z2 S0 and click "home all" the 3 axis are going all the way up, but they dont stop when they touch my end stop …

            I figured it out!
            my end switches where wired the wrong way! now my homing function works!
            Next step, auto- calibration!

              This is what happen when i execute the auto-calibration : https://youtu.be/g-fBQl13hDI

              The first calibration point works fine, but then the head twist … Any idea why the head twist like this ?
