Some good reads on troubleshooting issues with prints:
Great guides. Wish stuff that comprehensive was around a year ago.
Ultimaker forums use to have an article called “balancing the energies put in to a print”.
It’s focus was on balancing: Temperature and Speed, for a given material and print object size and details.
Can’t find it anymore, my link is 404. Too bad, it was my #1 must read for beginners.
