Ender 3 Pro BL Touch Trigger Height
-
when defining the grid you have to take the offset of the probe into consideration.
-
@Veti But when i defined the grid i used the probe as point of reference thats why in reality all that coordinates are indeed reachable.

post the output of
M208
and
G31 -

this does not match your config.
check all your files maybe you are overwriting it somewhere
-
Your Z probe is in front of the nozzle by 6mm, so it's unable to reach the Y position you've set in M557.
-
-
@Phaedrux no, it's behind the nozzle, maybe i wrongly put positive 6 when it is negative? That's why i am sure that every single coordinate can be reach i've saw myself the whole measurement and the probe can reach all of them fine.
-
Ah yes, sorry. Y6 would be behind the nozzle.
Veti pointed out the real issue.
M208 X230 Y210 Z200 S0
M557 X47:205 Y20:230 S20
Your M557 is asking it to go to 230 but your axis maximum is only 210. The error messages say it's skipped 220.

I am glad to report that now it's working. But just because i am a control freak i 've modified my bed so its better now and i am assuming that once i've done the compensation and save the height map the only thing that i need to do is just load that map at the beginning of the print.
Thanks guys

Yes, G29 S1 in the slicer start gcode after the G28 to home would be a good place.
-
@jcv1977 Hey, is that the editor in DWC? How did you get it to parse Sometimes as a valid gcode?
-
@b3njam1n Hey! just use the code snipet and paste your gcode inside it.
