Prusa Mini Linear Advance

Prusa supplies linear advance gcode for the MK series printers, but not for the Mini, so I decided to build one to…

Thank you very much for this. It printed well and taught me that my printer needed half as much K compared to what Prusa thought I did. It has helped me to at the very least smooth out the flat surfaces of my prints using input shaper. Now to tackle the infill not always touching the perimeters... 😅 (edited)

@Layers_191784 A step further to those perfect prints. :)

M900 K0.72
Would it be ideal?
Or which one would be better?

@Cutlas_343661 Looks like right between 0.64 and 0.72. So 0.68 :) However, it's really close, 0.72 might work perfectly fine.

Hi there I am trying to print this but my fast lines are not printing at all, it just sticks to my nozzle or clumps up instead, I can print any other object 100% fine, except for any pressure advance test, any ideas how I can fix this? I have already changed z-height from one extreme to another with zero difference. (edited)

@Buxton_220980 Make sure your bed is very clean, plain dawn dish soap and hot water works the best and then dial in your first layer again.

@Skreelink I thought my 70% alcohol would be enough but clearly not, after cleaning it with 99% IPA it is now significantly better and sticks easily. Letters are still a bit jumbled though.

Thanks for the test adapted for the mini.

Hi, I tried your stl on my mini Prusa which prints the corners a little rounded (swollen)..image circled in yellow. The print on the right is from a mk3s, what a perfect print. Do you think this could be the problem? I also attach the result of the stl linear advance printout. Thank you

@Taso_258096 Yes, incorrect linear advance is the cause of bulging corners as in your first image. It looks like you should be using 0.7-0.75 by your posted images. :) That should help your bulging corners.

@Skreelink thanks again friend. now I have to try to understand where to insert this data. At what temperature was this PLA test printed? I always print at 200°. Good night. (edited)

Worked perfectly! And it was very satisfying scraping the numbers off the bed afterwards 🤣 (edited)

@Machspace_924470 Numbers got WHEEEE when they pop off.

I modified for PETG for my test. Thanks!

@EngMike Neat, glad it worked and you could modify for your needs. :)

@Parra That really shows the difference, awesome.

So my issue was unrelated to LA, but this file was helpful in checking it off the list. Thanks

@Kraiden Glad it helped. :) That's why I make things like this, helps mark things off when troubleshooting.
