This right here is really strange. 5 mm retraction? Everybody who actually gets things to print decently uses less than 1 mm after lots of trial and error, but this is of course outside of luban at that point.
@brent113 any comment this this line from Edwin specifically???
Now, i am going to rant a bit, and its not even really intended to attack anybody or snapmaker or anything… it is just what I am feeling going through all this over time.
I think when this machine was designed, and all factory settings applied, they had a concept of how 3d printing worked, but it was outdated and i think the firmware is not doing things properly as a result of it.
This is the same story about the linear advance, it comes from the factory way out of tune, because luban is set up in such a way that it doesnt matter, but when you go to use a real slicer things arent right anymore. we are all trying to make things proper per tested well accepted best practices, but the machine itself isnt designed to work in a best practice format. so its like all these things everyone has been working towards is just shifting the problems someplace else, because there is something not right in the firmware.
in other words, luban slices things differently than other slicers do, to accomodate the firmware in the machine, and any substansial changes to make something better in an effort to improve the performance of the machine are just undoing everything they shipped in an effort to get luban to work a certain way.
just my opinion of course… Snapmaker is missing the bigger picture by focusing its efforts on changing the machine for luban’s sake instead of changing luban & the firmware for the sake of best practices.
