help to setup M557 Mesh size

Veti

you have to define the mesh with the probe offset in mind.

so you minimum probe points would be x41.2 z4,5 as the points are based on the head and not the probe

lui2004

thank you after cahnged i got this error:

G29
Warning: Skipping grid point (15.0, 15.0) because Z probe cannot reach it
Warning: Skipping grid point (35.0, 15.0) because Z probe cannot reach it

jay_s_uk

What have you changed it to? Can you confirm?

lui2004

@jay_s_uk

i have change only bltouch offset from negativ to positive nothing else

jay_s_uk

@lui2004 thats not what was meant

G31 P25 X-39.5 Y-5.2 Z1.051
M557 X41.5:215 Y15:195 S20                       ; define mesh grid

is what you should have

lui2004

@jay_s_uk

like this:

G31 P25 X41.2 Y4.5 Z1.051
M557 X41.5:215 Y15:195 S20 ; define mesh grid

jay_s_uk

No, as per the adjusted code I posted above

If you change the location of where the BLtouch is, the firmware would have the location of the nozzle in the wrong place

jay_s_uk

unless of course your BLtouch is not where you originally said it was.

lui2004

i have measure once again the bltouch offset:

the correct is: x 41.2 and y 4.5

Veti

@lui2004

post a picture so that we can verify

lui2004

@Veti

i have this mounted:
https://www.thingiverse.com/thing:3781222

and this is my acctual config:

G31 P25 X41.2 Y4.5 Z1.051
M557 X41.2:215 Y15:195 S20 ; define mesh grid

jay_s_uk

so assuming that 0 is on the left, the bltouch is mounted at X-41.2.

where is Y when its homed?

lui2004

Y is on 3

jay_s_uk

so...

G31 P25 X-41.2 Y4.5 Z1.051
M557 X41.5:215 Y15:195 S20                       ; define mesh grid

lui2004

i have inserto your data now

but now when i make G29 it will not measure all the left side
