hbot homes correctly but prints mirrored ,

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

both move in a positive , to the top right side of the printer

If the head moves diagonally in the +X and +Y directions, all is well.

Move on to the next direction move test.

When you have the X motor moving correctly, test the Y motor by sending from the console:

G91
G1 S2 Y10 F3000

If the head moves diagonally in the +X and -Y directions, all is well. If it moves in the -X and +Y directions, change the S parameter in the M569 P1 command to S1.

Y+ meaning to the back

tracar

x pos
y neg

Phaedrux

Alright, so now when you jog the print head normally, does +x go to the right and Y+ to the back?

Have you changed your homing files to move to Y positive?

tracar

jogging is correct

y homing needs to be reversed

@Phaedrux

There is also some positive move need to go minus , eg the back off the end stop move , or they will push into the back stop instead of backing off.
So like I said don't change invert all y moves.

tracar

homeall works
homex ,and homey work
and......x y jog work in the right way

@tracar

So all you need to do now is set the Z offset ?

z always worked right

peter247

@tracar

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

peter247

@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

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

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:

@tracar

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
