My printer’s been working well for awhile now so I feel like it’s time to break it by trying to make it print better 
I’ve noticed that I’ve got some artifacts that look a lot like the “ringing” described in the post linked below. I’d like to spend some time tuning the machine to see if I can eliminate this stuff but I’m wondering if there’s a more current guide like this and in particular, one that covers the i2 Prusa Mendel and Marlin firmware.
Any recommendations?
