Printing issue: detail falls down!
Hello, we are a team printing the Poppy robot (https://www.poppy-project.org/) with Wanhao Duplicator 4 using PLA.
We have a trouble when printing tall parts such as forearms:
- in the first 5-6 centimetres, everything goes well.
- Later, extruder starts to damage printed surface touching it
- Then extruder move the detail and it falls down

Did you have the same problem and if yes, how did you solve it? We assume that the problem is in fault that accumulates with time. Can you advise something?
