I did contact support and looks like the parts will be on the way.

As for the temp. I was trying to print ABS which apparently it will not do. Do you run your PLA at 35C chamber temp? I will give that a try. I am having an issue with the print separating from the raft. It only happens on the right side of the build platform. Maybe the chamber temp will help.

As for the filament... I made a spool holder that mounts to the side. I still have tension issues, but is seems to be better.

Do you mind sharing some of the modified settings you have started using? I made the raft a little wider, that is about all, other than playing with temp settings a bit.

I will try to get you a few links over the next couple of days...
