hbot homes correctly but prints mirrored ,

So Zero mm is zero mm from the bed ?

tracar

all thats left to get back is the bltouch settings and independant z axis for bed leveling

tracar

@peter247 yes z0 is Zero

after it homes to z0 it backs off 5mm

@tracar

So what is next to do bed.g / G32 ?

tracar

next is to get it to recognize it has a bltouch attached, as M280 P7 S10 :deploy bltouch does not work

M280 P7 S10

If we're using RRF3 now, that should be P0 instead of P7.

There should be an M950 command in your config.g that create the servo 0 pin for the bltouch. That's where the zero comes from.

Doing up a diagram like this can be very helpful in getting the offsets all straight. Piece of grid paper works well if you're not a paint wiz.

There's also some useful info here:

This page will also be useful for getting the hang of RRF3:

And of course the Gcode wiki that will tell you how each gcode works:

Which heater pin are you using ?.

Mine is heater 7 , so this should help you .

; Z-Probe config.g

M558 P9 C"^zprobe.in" H2 F100 T8000 A5		; set Z probe type to bltouch and the dive height + speeds
M950 S0 C"exp.heater7"							; create servo pin 0 for BLTouch
G31 P500 X-45 Y-6 Z2.98                        	; set Z probe trigger value, offset and trigger height
M557 X55:295 Y55:295 S80                     	; define mesh grid .. 30 , 60 , 80

Lines 5 and 6 set to your own offsets and mesh grid
This works with any heater

; deployprobe.g
; called to deploy a physical Z probe
;
M280 P0 S10 ; deploy BLTouch

; retractprobe.g
; called to retract a physical Z probe
;
M280 P0 S90 ; retract BLTouch

tracar

yes H7_pwm on the end of the expansion board

can not get a response from the bltouch

; Self-Test
;
M280 P0 S120 ; Send PWM channel 7 the S10 (angle) command, inverted signal

@tracar said in hbot homes correctly but prints mirrored ,:

can not get a response from the bltouch

And that's using this in your config,g?

M558 P9 C"^zprobe.in" H2 F100 T8000 A5 ; set Z probe type to bltouch and the dive height + speeds
M950 S0 C"exp.heater7" ; create servo pin 0 for BLTouch

If that's what you have in config, and it's wired to the right pin, check the wiring continuity.

tracar

this is the current config

; Z-Probe

M950 S0 C"exp.heater7" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T24000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z0.445 ; set Z probe trigger value, offset and trigger height
M557 X50:400 Y50:500 S50 ; define mesh grid

and

; deployprobe.g
; called to deploy a physical Z probe
M280 P7 S10 ; deploy BLTouch
does not work

continuity of wiring is fine

@tracar

BIG HINT ,This works with any heater

; deployprobe.g
; called to deploy a physical Z probe
;
M280 P0 S10 ; deploy BLTouch

; retractprobe.g
; called to retract a physical Z probe
;
M280 P0 S90 ; retract BLTouch

tracar

i have already changed the p0 and still non responsive

peter247

@tracar , what pin are you using .

tracar

@tracar said in hbot homes correctly but prints mirrored ,:

H7_pwm on the expansion board
and zprobe in

peter247

@tracar Pin 31 ?

tracar

@peter247 yes

I can't see anything wrong with the set ups .

if you had a Maestro that needs to be set up differently , but you are running a duet 2 wifi , so that doesn't wash .

Can only think it's wiring ?
