topic_solved Home all axis at once
Saktziki last edited by Saktziki
I was wondering if there's a good way to home the XYZ axis all at once? Right now I homeall.g I home one axis at a time but because the printer is quite large it takes quite a long time.
Thanks in advanced!
@chrishamm Okey so then I'll put in a separate G1 H1 command and not call each home script individually??

@saktziki below is my homing script which homes all axis at the same time however be aware that this is for a delta so all are home to max but it may give you a clue.

Awesome that works! But now I encountered a different problem. I back away from the endstops and the approach them slowly again but they don't stop.
This is my code:
; Clear any bed transforms M561 ; Clear babystepping M290 R0 S0 ; Set to Relative Positioning G91 ; Move Z down so we don't drag it on the bed G1 H1 F300 Z1 ; Set to Absolute Positioning G90 ; Move if not stopped by endstop first G1 H1 F1200 X700 Y475 Z900 M400 ; Back off endstop slowly G1 H0 F240 X-5 Y-5 Z-10 M400 ; Move to endstop again, slowly G1 H1 F120 X15 Y15 Z20 ; Wait M400 ; Set position G92 X645.00 Y445.00 Z576.6 ; Wait 500 ms G4 P500 ;; Move from endstop by 1mm G1 F720 X-1 Y-1 Z-5 ; Set to Absolute Positioning G90
@saktziki if it's a Cartesian printer, see https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_The_homeall_g_file. This shows how to home X and Y together. If Z uses an endstop switch then you could also home Z at the same time.
@dc42 Thank you so much! I got it to work now
