I’m pretty new to 3D printing, but have been teaching my middle school students how to model in Tinker Cad, and slice using CURA to print to our new Taz Sidekick 747. We’ve been very successful for a couple months - having gone through about 4 rolls of filament. Recently, I had to transport the printer. Since then (coincidentally or not) our prints have been sort of squished.
I am attaching some pics of a Benchy I printed a while back (white), and one I just printed (grey). As I hope you can see, the new one is very rough, and the height is at least 1/4 inch shorter.
I could sure use (detailed) advice if someone can help a new user.
