  1. Hi there, I have been doing good quality prints on my Ultimaker 2 from the beginning, (I have it since about four months). But since a while I started to have under extrusion on most of my print and that was append with any filaments I have (all my filaments are from from ultimaker) Also I was using the same settings of before, when my print was good. I tried everything I can to fix it, changing the temperature of the nozzle, the bed and many settings. I made a lot of atomic method to clean the nozzle, I dismounted the nozzle to checked the teflon. I also tried the alternative feeder from Robert and printed a bowden hook to try to improve the flow. https://www.youmagine.com/designs/yet-another-ultimaker-2-feeder https://www.youmagine.com/designs/bowden-hook In the same idea I removed the spool and unwound the filament to reduce the tension, after I read that here : http://ultimaker2prints.blogspot.ch/2014/11/dont-over-tighten-material-feeder.html All of theses things wasn’t really a success and the under extrusion was stil there ! I was wondering what can be changed on my printer, and after one week of testing I remember I did a firmware update (15.02.1) Then I Downgraded to the firmware version 14.12.1 and magical! Since I did the downgrade I did not have anymore obvious under extrusion. Is someone know or/and have the same issue ? Cheers, Boris.
  2. :-) I was looking in the options of the printer and in cura to move the print head, but the solution was so simple ! Thanks ! PS: By the way it will nice to have an option to move the print head in the maintenance menu.
  3. Hi, Is there a way to move the print head in front (or where we want) manually ? For exemple to be more confortable to clean the nozzle. Boris.
