help to setup M557 Mesh size

lui2004

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

@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

try

after homing can you jog to X0 Y0 and make a photo

Best

lui2004

after homing my printer go to middle

0,0 is back right ( Ender 5 )

ok at 0/0 you are in the right back corner?

edit: should have read your first post
