Mesh Inset

[bedfelllow]

The wiki says "Mesh Inset doesn't actually save after restart, so this must be done after the printer is turned on every time (until the issue is fixed).*". Could this not be overcome by setting #define PROBING_MARGIN in the firmware?

Yes, it can, but that's a different number for a lot of people. I personally build my own configuration of this firmware so I can make my printer behave how I want, but making 300 separate releases just for differences in that margin is absolutely not worth it.
The ease of access depends on people who might not be willing to or have the time to dedicate to building their own customized firmware being able to just upload one that's preconfigured (as much as possible for them) to their liking.

The importance of this issue is that while it could be fixed like that, it's important to outline the details for people that need that mesh inset option. Until the issue is fixed, there's no better (and easier or faster) solution to the problem.

I'm not so sure if changing the probing margin would have the mesh inset save.

I think it may be possible to hard code the value directly in the firmware, but as for now I'm not sure how to go about having the mesh inset save. there is a certain code in the library in the lib/proui.a files that I'm unable to access, it is Mriscoc himself who would know how and what to change.

I'm thinking that if the code can be renamed or referenced differently, it make work. that is just out of my pay grade, so for now someone else who knows what to do can tackle that and address it, or we can hope to wait for the actual author to change the files that were are unable to do ourselves.

I just wanted to update this discussion for prosperity.

I believe it was sometime in June I was able to make a workaround for the Mesh Inset save issue. before if you had a probe, the mesh inset would be limited by the Probe's offset, so when you would probe the bed to build a mesh, SURE you would have all the points it calls for to probe, but the Mesh itself is smaller. The mesh would only go so far and not actually in the areas it could not probe otherwise. However, in Marlin after the G29 P[1/2/3] (im forgetting which number it was, P1 I think) when the probe completes it's job, you may notice not all the probe points were actually probed for their values.

that is okay because it automatically calculates the unprobed area with great precision. so having the Mesh Inset being limited within the probe's area is not necessary. So in the work around, I was able to make it work - as in save after restart - since it did not save the Mesh Inset after restart. for instance if you wanted the FULL bed to include the Mesh, when you go to turn off, the settings would not save and revert back to original, or if you have a Probe X offset of 45, and the Max X position it can move is 230, the most the Max X Mesh Inset would be is 185. Meaning if you wanted to print something past 185 in the X axis, bed leveling would not be used because it has limited the Mesh up to that point.

Everything is working as it should now, it may be a temporary fix for now, but all is good regarding that. I want to make note that the settings should be stored (saved) and the printer should be restarted after the initial flash/install of the firmware so the settings can take place.
