On this particular model (which is build up mainly by tubes), the printer manages to print the ‘start-up’ framework, but when it comes to the tubes, it seems to loose contact and the PLA is no longer printed on top of the model.
I only noticed it when the head was already 5 mm from the model, and a blob of PLA was hanging on the tip of the head.
Has anyone experience with this? Should i change some settings. (This is only my 3rd print.)
