  1. I will test that. With the last print however you are able to see that the print started well in-between had massive under extrusion and then finished well. I would expect a no print at all or well print which is why I started to think that this must be a feeder issue
  2. It seems to me this was really more a feeder issue not nozzle or print plate. I have 2 0.8 nozzels (actually 2 complete nozzle sets) and the issue happens mainly with 0.8, less with 0.6 and hardly at all with 0.4 I changed the tension and it seems to have helped. I will do another big print today.
  3. Maybe I should not have praised the day before watching the even TV scheduke totally inacceptable layer gabs
  4. All I did was to adjust the feeder tension and this seems to have helped
  5. I did a test cube print and it failed too So I took off the print bed and washed it both sides and put it pack and the test cube print worked again instantly Then i removed the parts to print the main design a s again this failure this is just bonkers Printing the test cube again works
  6. After this crap print I calibrated the print bed again with the build in function and then with some test prints to check corners. I had one 98% good print that showed only at two layers issues - which however is already not good and all following prints are horrible again. Below are two print attempts of the same mode ... @gr5 I am not sure if you could maybe point me towards a solution. Can the PLA be old or the print glass surface have issues?
  7. Ultimaker 2+. PLA Using glue stick recently I cleaned calibrated the printer but printing with it is a hit or miss there is always the issue of under extrusion sometimes this happens already on the glass surface sometimes and mainly this append in the part the printer was not used that much and worked perfectly before - was not used for over a year and a half attached are some images to show the issue i had the feeling this might be a feeder issue but mainly the test extrusion of material before printing looks amount wise fine and also based on the nozzle and layer setting I get different results. any help from Ultimaker would be highly appreciated
  8. The print issue remains no matter what cura version or print speed.
  9. So I did two things: I used the old Cura 15 and in the current Cura I set all printing values to 30. However the print result is the same. At the Lulzbot forum the staff mentioned to me that the start end line I see is just the way how it is with their MOARstruder and I think this might be the same with the Ultimaker 2+ and the 0.8 nozzle. I have a pencil holder (cone shape) I printed with the Ultimaker but I dont recall the nozzle size but it was not the 0.8 nozzle. The print is flawless.
  10. When using an older Cura version do you also have to flash the older firmware?
  11. Ok now I am lost hahah Print slower and solution is increase acceleration?
  12. I think it always starts inside, then the inner wall then prints the outer wall. used the ultimaker 2+ 2 years ago and I swear I never saw those issues.
  13. 0.8 nozzle 0.4 line width (I think) randome z alignment notice the dimples where a new layer starts ! How can that be filled / fixed ?
  14. 0.8 nozzle i have very good result when using 0.4 line width but with 0.6 line width I often get those noodle sculptures interestingly the base layers often are fine
