Darn it, I replaced the HBP cable already, I should not have to deal with this again. Talked to makerbot, sounds like they're shipping me a new one so I'll give it another shot, but I hope there's some advice to prevent this from happening again.
At least this time it's still printing. Makerbot says not to worry as long as it works. Which is good, I've got some prints I want to do this weekend and I'm in the middle of playing with smoothing with acetone fog. I just hope I'm not running this thing into the ground.
