Saving mesh leveling data to EEPROM

Hi,

We have been using the i3 MK2 for a while now, and it's a fantastic printer. We are using it for a very specific purpose; printing on top of an existing fixture, also printed and attached to the bed surface. This fixture is static (is never removed from the bed, since there's no need to do so) , and keeps another 3D-print in place, while printing on top of it.

In this case, we are not able to perform the mesh leveling before each print, because the extruder head would collide with the fixture.

- Is there any way to save the mesh leveling matrix, so that we wouldn't have to perform the mesh leveling before each print? Or maybe another creative solution to our problem?

Re: Saving mesh leveling data to EEPROM

As far as I understand you, you are printing on another object. So you start your prints a certain height above the heated bed, right?
So when you know how to start a print in "air" (at heights > 0 mm) all you need to do is to deactivate mesh bed leveling, as it will be of no use on your printing surface.

In order to do so, check the start gcode of you slicer and find the command:
G80 ; mesh bed leveling

Delete this line or simply stop it from being executed by writing a semicolon infront of it:
;G80 ; mesh bed leveling

Each time you slice a model with this settings, your printer won't do the mesh bed leveling process.

Hi Sherlock,

Thank you for answering. I guess my question wasn't very clear.

Yes, we are printing on top of another object. And we have already removed the bed leveling routine from our prints. The problem arises, when the lack of bed leveling ruins the print.
`
So; we need the mesh leveling data, for printing on top of another object. But we can't run the leveling routine before each print.

Is there anyway of reading out the data, or manually entering it - maybe in the gcode itself?

Simon,

The G80 code is how you would apply your bed levelling values.

Read the Hyperfine Bed Levelling thread to learn how to get the values you need and then add them to your start code.

Did you figure out how to print without first doing the mesh-bed leveling? I am trying to do the same as you are doing, print on an object on the bed.
I have been going through the Hyperfine Bed Levelling thread, but cannot really find what I need to do. Hope you can help.
