What going on with those striations? It looks like Linear advance in on and turns itself ff shortly thereafter . For me, Lin advance does exactly what it’s supposed to, corners are sharp and pointy, printing faster and most importantly, no ooze with PLA. Wondering why it’s not working for you? Im sure if this were a software glitch there’d be more Marlin users reporting problems.
Again, I’d be closely inspecting the log files for messages that might help.
Are you referring to the corners? I guess I didn’t explain…I was testing different k values .8-1.2 with a value of 0 between each illustrating my frustration that the print has less bulges in the corner WTHOUT lin adv enabled than with it enabled.
