I'm actually using ABS. After fine-tuning the bed more precisely, using a wide brim and hairspray, I'm getting it to stick so well it's actually pretty hard to get off.

One vague problem I had this morning is that about 1.5 hours into a 2.5-hour print, it just abruptly stopped and logged the error "communication timeout reset send buffer block". It happened just a moment after I unplugged and re-plugged my laptop charger, and the laptop kept running normally. I'm certain it was the laptop plug, not the printer. I don't know if the timing of the error was a coincidence. I've googled around about that error message, and people talk a lot about the importance of setting an optimal baud rate. Do you have any insight into what may have caused the unexpected stop? And/or recommendations on baud rate?

Thanks so much for taking the time to chime in, tjnamtiw! I'm doing my first print! You've gotten me a lot further along with that input. It's running pretty smoothly so far, except that the bottom corners are peeling up a bit. But I'm sure that can be mitigated with fine-tuning.

One strange thing I'm noticing is that when I home the X axis, it bounces. What I mean is that it moves toward the stopper until it hits it. Then it immediately backs off it for a moment, then it moves back over and reestablishes contact. Is that normal? The Y and Z axes don't do that.
