  1. Thanks. I did some more test print with different settings on "Initial Layer Flow" in Cura. Pictures appended are taken upside down with 100% and 125%. What bothers me is that it really only is the first layer that are underextruded. The rest of the print is of very good quality. I found the TFM coupler as spare part (e.g. here: https://www.igo3d.com/Ultimaker-TFM-Isolator-Coupler-UM2-), but I did not find the spacer you mentioned. Where do I get it? If I disassemble the print head, I want to do both at the same time.
  2. Hi everybody, I just got my hands on an Ultimaker 2 sitting in an attic for about five years, together with several spools of PLA filament. After some cleaning and greasing I got the printer to print again, but I do have problems with the bottom layer, it has space between the lines of PLA. Bed adhesion is good, I leveled the bed again and let very small room between nozzle and bed, but still got the issue. My question is: Can this be a result of the material which is over 5 years old? Does PLA age? The top layer is of good quality, no holes in there. I just want to avoid to spend to much time if the solution is to get rid of all the old PLA. Thanks, Chris
