I finally leveled my printer bed and verified that my tape covering had the proper clearance.
So I made a test print of a 3D mars map. At this scale, it was less than impressive, but I wanted to see how well it could be printed.
Now I noticed that the layers did not melt together. Does anyone have an idea as to why? I am using PLA that came with the printer, so I wonder if it is just too old or possibly absorbed too much moisture.
So now I can move on to designing my neck brace and see if it can be printed by the printerbot Jr.
More to follow.
