hello dear

i have a problem strugling from the first day build.
now i have genuine BLTouch v3.0 still the same problem i can print only on one side of the bed
other part are high level cant touch the bed and right side nozzle cuts the PEI sheet.

i used pronterface with G29 command it gives me this results

0 1 2
0 -0.043 -3.120 -8.118
1 -0.338 -0.713 -1.888
2 -0.548 -2.315 +0.055

and this is from repetier
13:43:55.396 : Bilinear Leveling Grid:
13:43:55.396 : 0 1 2
13:43:55.396 : 0 -0.058 -3.003 -7.795
13:43:55.396 : 1 -0.268 -0.553 -1.782
13:43:55.396 : 2 -0.482 -2.177 +0.135

as you can see bed level is not right but meaning of using BLtouch should fix this leveling right
is there any small point that i am missing to work this out.

im bussy with printing of CNC parts small pars are ok to me but with large parts its impossible

kindly

Hi Reis,

Do you want to mean that the nozzle touch the bed before the BlTouch be triggered ?
If yes, you just have to put M3 washers between the Bltouch body and its printed support.
And set a new Z offset.

hello Romain

Nozlle touches not every part of the heatbed its like my hetabed is bended or deformed.
if its deformed or bended why bltouch should that calculate and adjust the hight i guess.
