I decided to do a slightly larger print. I think I finally got all the settings dialed in for success. And then failure struck.
For some reason it not only stopped moving up on the z axis. It actually lowered for some reason - and the heated tip fused into the piece (and im pretty sure bent the tip) not a great way to start. On the plus side none of the servos burned out and I was able to jog in all directions after removing the printing module.
Now i have to figure out how to change the tip. Wasn’t expecting to have to on my third print.
Any ideas what caused this problem?
