Bl touch issues not homing z with bl touch .

@peter247 said in Bl touch issues not homing z with bl touch .:
and for Z probe end stop I have , M574 Z1 S2
See my reply above. Use
M574 Z0, or leave out the line entirely, as it's not needed. The Z axis allow you to have an endstop (eg max endstop, useful if you want to rehome after a mid-print power loss) as well as homing with a probe. If you added the endstop, you would need to define M574. So if you're using the probe to set Z at axis minimum, it effectively ignores any M574 setting for Z.Ian

ok i did a few things and seem to get a little further . now when i do auto homing x and y does fine . when it starts to so z - the y moves to center as it should then x moves all the way to the right until i have to unplug it .

ok i think i got it , but my bed is 220mm and when it starts to probe z its off the bed how do i center the bed and get the mesh points right ?
x and y do fine but z is not at the right points -
@morf33 o.k the bits you need to set are :
; Z-Probe
G31 P500 X-45 Y0 Z3 ; set Z probe trigger value, offset and trigger height
M557 X55:295 Y55:295 S60 ; define mesh gridThis is for my 350x350 bed , and the offset it from the nozzle to the probe .
So my probe is level to the nozzle in the Y axis , and the probe is 45mm to the left which is a minus eg <--- is a minus >------ is a plus on the X axis .
and 3mm from the probe touch to the bed !!!The M557 , x min , x max , so for me 55mm and 350 - 55mm ( 295 ) and the same for Y, the S60 is Steps of 60mm.
SO If the probe is 22mm right of the nozzle that is G31 X22 , and in front of the fan 50mm from the nozzle that makes in -50mm , so G31 x22 y-50
If I want to home in the centre off the bed I need to add the offsets in my case.
eg 350 / 2 + 45 , now the probe is in the centre not the nozzle. ( Homing files ) -

Remove that part from your homeall.
It also looks like you are running firmware 3.1. There was a bug fix update 3.1.1 that you should be using.

wow ok this is back to yesterdays issue . bl touch works now but when homing z , x and y do fine and z goes all the way to the right . upgraded the firmware see below for homeall ,config and firmware version

now the z wont go down and then the bltouch proble extends then it retracts after a min and gives this error .
G28
Error: Z probe was not triggered during probing move -
G92 Z0 ; set Z position to axis minimum (you may want to adjust this)
Try to remove that line in homeall.g and in homez.g
That sets Z to 0 and the firmware will not drive Z outside of the limits.
The line only makes sense if you use a Z-endstop for homing, maybe it's a left over from an older setup.Edit:
G1 X15.5 Y35 F4000 ; Move probe to middle of bed
Also adjust x and y values. That is not the middle of the bed.... -
all is good now , thank you all for the assistance
