I managed to succeed with my first print using ColorFabb XT last night. I used the Laybrick profile and adjusted the temperatures:
However I had to move the print job off the center of the bed to get it to print properly. You can see the outline of a previous attempt on the bed in the center. Essentially what happened is that the print head would move over the close and left side of the bed but not extrude anything. When it moved over the far and right part of the bed, it printed normally. As a test, I moved the model to where you see it now, and it printed normally (so I let it finish).
This is happening again this morning with the next piece I intend to print:
Can anyone explain why this is happening? I looked online through some common problem guides but found nothing similar.
The piece currently printing is this one: https://github.com/zdayton/DeltaThrottle/blob/master/stl/Base_rev2.stl
Yesterday’s piece that did the same thing until I moved it on the bed is this one: https://github.com/zdayton/DeltaThrottle/blob/master/stl/Handle_2_bottom.stl
In the log the following errors can be seen, not sure if they’re related as yesterday’s successful print also had some errors like this:

Also you can see damage to the bed that happened when I tried to remove yesterday’s piece. I waited until the bed was less than 30C in temp before I even started to remove it (which took far longer than 20 minutes), based on how long it took to remove even the single layer failed prints from yesterday. I had to take a razor blade around all the edges and then carefully pry with the clam knife, and it still ripped the bed. What can I do about the bed damage, and how can I get this material to not stick so strongly?
The Mini is now “printing” the second layer and the problem continues, by the way.
Edit: Here’s a picture taken as the second layer nears “completion”:
After aborting the print I can get a better image:
