Hi,
I purchased the Ultimaker 2 a few months ago and everything has been going great, however recently the feeder mechanism has been making high pitched sounds.
Basically, when it starts printing and the mechanism at the back pushes and pulls more material, each time it does it, is sounds like a creaking door? If it was a creaking door I would use WD40, but seeing as this mechanism also grips the material, I don't want to spray anything in there as it will probably hinder it.
Has anyone else had this or know how to resolve it?
Thanks in advance.
Chris
