Homing reset before complete

pajacyk0v

Hi,

I installed new 6HC with latest stable RF 3.3 on my printer. Form the begining I have problem with homing procedure. When printer is powered on first homing allways act as following:

carriage going fast to X endstop
stops on endstop
move backward
going slow to X endstop
stops on endstop
carriage going fast to Y endstop
stops just before endstop (!!!)
run G28 again (!!!) with succeed
throws Error: G0/G1: insufficient axes homed

It only happens when printer lost coordinates. If homing suceed once, all another attempts also succeed
All endstops are optical (NO) form TriangleLabs. Printer with CoreXY kinematics.

homeall.g

G91                     ; relative positioning
G1 H2 Z8 F600          ; lift Z relative to current position
G1 H1 X-235 F4800 ; move quickly to X axis endstop and stop there (first pass)
G1 X5 F4800       ; go back a few mm
G1 H1 X-235 F600  ; move slowly to X axis endstop once more (second pass)
G1 H1 Y-275 F4800 ; move quickly to Y axis endstop and stop there (first pass)
G1 Y5 F4800       ; go back a few mm
G1 H1 Y-275 F600  ; move slowly to Y axis endstop once more (second pass)
G90                     ; absolute positioning
G1 X107 Y127 F4800         ; go to first bed probe point and home Z
G30                     ; home Z by probing the bed

kinematics settings are following (config.g)

M669 K1                                               ; select CoreXY mode
M569 P0.0 S0 D2
M569 P0.1 S0 D2
M584 X0.0 Y0.1 Z0.2 E0.3                              ; set drive mapping
M350 X16 Y16 Z8 E64 I1                             ; configure microstepping without interpolation
M208 X0 Y-22 Z0 S1					    ; set axis minima
M208 X215 Y255 Z440 S0                                ; set axis maxima
M574 X1 S1 P"io1.in"                                  ; configure active-high endstop for low end on X via pin io1.in NO
M574 Y1 S1 P"io2.in"                                  ; configure active-high endstop for low end on Y via pin io2.in NO

@pajacyk0v said in Homing reset before complete:

stops just before endstop (!!!)

its possibly not moving far enough?

Your Y axis length is specified as 277mm (-22 to +255) but your homing file only moves 275mm

Try changing this line in your homing file
from this:

G1 H1 Y-275 F4800 ; move quickly to Y axis endstop and stop there (first pass)

to this:

G1 H1 Y-300 F4800 ; move quickly to Y axis endstop and stop there (first pass)

@t3p3tony OMG! I looked into gcode soo long and I didn't notice that bed toolbar have negative values XD

@t3p3tony you were rigtht. I'm an idiot
