hbot homes correctly but prints mirrored ,

@tracar

You do need to change the Y homing files , but I think you may have to play to get the direction correct.

Don't forget to invert all the moves or the G1 Y5 F800 will push it into the end stop.

Phaedrux

The homing direction for Y should be positive direction to the endstop at the rear.

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

M569 P0 S0 ; X motor runs forwards
M569 P1 S0 ; Y motor runs forwards

im not using the built in drivers , all are external
my config is currently this for x and y:
M569 P5 S1 T5 R1 ; physical drive x goes forwards
M569 P6 S1 T5 R1 ; physical drive y goes forwards

Ok, well the idea is that you're setting the motors to rotate in a forward direction, however you do that. I believe that would make it clockwise.

tracar

i have set to this
M569 P5 S0 T5 R1 ; physical drive x goes forwards
M569 P6 S0 T5 R1 ; physical drive y goes forwards

the
G91
G1 S2 X10 F3000

they both move towards the back left corner (where the endstops are )
so x moves in a negative and y in a positive

Phaedrux

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

so x moves in a negative and y in a positive

If it moves towards +X and -Y, or towards -X and +Y, then either turn the power off and swap the X and Y motor connections, or use M584 in config.g to swap the X and Y motor drivers over.

So swap your X and Y motor plugs.

tracar

changed drives to :
M584 X6 Y5 Z7:8 E3 ; set drive mapping

now with

G91
G1 S2 X10 F3000

x and y move to the negative. so heading x to 0 and y to 0
which is the front left side of the printer.

Phaedrux

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

x and y move to the negative.

If it moves in the -X and -Y directions, change the S parameter to S1 in the M569 P0 command. Or in your case, flip the direction on your external stepper for the P0 driver, labeled as X.

Actually that might be wrong because you've now remapped which driver X is assigned to. You're now using driver 6? Flip that one.

tracar

; Drives
M569 P5 S0 T5 R1 ; physical drive y goes forwards
M569 P6 S1 T5 R1 ; physical drive x goes forwards

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

peter247

@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
