Compensation and calibration issues
-
Hello all,
I am working on a large format printer 1100x1100x1100 build volume, and when I tell the printer to either true bed level or to do mesh compensation it only runs on a small section of the build plate. I have redefined the mesh calibration area, however when run it says that it cannot reach points and skips them only to go back to the same small area on the build plate. Any help would be much appreciated.
thanks,

Here is what the consul says when one of the calibrations are run.

In the G31, is your probe really 570mm away from your nozzle in X and Y?
-
@jay_s_uk ah, no. Those are values generated by RRF configurator, will adjust those values.

@Tpmoses said in Compensation and calibration issues:
Those are values generated by RRF configurator, will adjust those values.
the default in the configurator for the values are 0
-
@Tpmoses
Once you've set those, the majority of your issues should go.
Just remember that you need to consider the offset in M557 as its not taken into account.
e.g. if your probe is 50mm to the left of your nozzle, it won't be able to reach the last 50mm of your bed on the right unless nozzle can go off by 50mm (and the M208 maxima reflects this)
