Yes, thats what i am saying

i can home X and Y first and when i home z it failes
if i home all it homes X and Y and failes with z

i tried adding S2 to this line and without that line, but in both cases Z wont home

I did, otherwise i couldn't home X and Y

or did I miss something else?

Hi,
i tried to adjust my homing files for my Cartesian Printer
Homing X and Y works again, but home z just moves the 5 up and then stops with

G28 Z
Error: G0/G1: insufficient axes homed

myhomez.g:
G91
G1 Z5 F6000 S2
; Back to absolute positioning
G90
; Go to first bed probe point and home the Z axis

can i use
M301 H1 S0.50 ; Set heater 1 output scale factor to 50%
or is this something different?

Hi,
