Linear Advance 1.5 / Marlin 1.1.9 April 24, 2020 02:56PM |
Hello 
I was curious about the linear_advance feature and decided to give it a try.
I followed the steps on the homepage to calibrate the k-value. For my setup 0.7 works best.
I enabled linear advance in the firmware and reuploaded it on my board (ender 5 stock board). I'm using the method to put the k-value in the start g-code. Everything works fine to this point.
NOW
After I finished printing some test cubes (the first one with a k-value of 0.7, the second one with a k-value of 0, few other k-values afterwards) I noticed that all of them look EXACTLY the same. Print Speed is set to 100 mm/s.
The only difference I noticed is that the print takes A LOT more time. This gets worse as I increase the K-Value. I can also see this when I watch the extruder.
This definitely not what I was exspecting. I tried everything I could find, but I can't get it work.
Any ideas?
