Thanks for all your interest. This Ultimaker is now sold.

Purchased new in August 2018. Printer still in nearly new condition. Only printed a dozen parts. There is still some filament left from the original demo rolls which will be included with the UM3. Total hot time on the print heads ~3 days (BB 0.4mm head) and ~6 days (AA 0.4mm head). Also comes with one brand new (never used) AA 0.4mm print head and PolyMaker dry box. Local pickup preferred. Comes with original box & packaging. Selling as I am going back to school and no longer need the machine. Asking $2800 CAD.

Thank you @kmanstudios. I would love to see my UM running smoothly with PVA like yours. I guess I will have to continue my search to control humidity better.

Thank you @JohnInOttawa. I also thought it was the humidity at first so I bake-dried and sealed with desiccant, etc. But I think it's interesting that my PVA stops extruding at the same height regardless of the print size. (I have a larger print that also failed to extrude PVA at a nearly the same height level.) So now I'm thinking it might be Cura related?

This past week, every print with PVA has failed on my Ultimaker 3. Here is what I have done so far. 1. For example, during print#1 shown below, it stopped extruding PVA (printcore was just going around without PVA extruded). 2. I baked PVA on Ultimaker build plate at 50 degreeC for 2 hours. 3. Hot-pulled the hotend until clean. 4. At the start of print#2, PVA was extruded clean. 5. During print#2, PVA extruded better with no missing gaps, but stopped extruding at nearly the same level as print#1. 6. Feeder's moving back and forth ok. (however PVA at the feeder's been grinding to a varying degree to the point where for a large print it snapped) 7. I've always kept the filaments in a sealed bag with desiccant. 8. I'm using UM filaments. I'm really hoping that someone can help me out here! Thanks.

I agreed with Dim3nsioneer in terms of diagnose and disabled the jet setting. I also set "SeamCornerPreference" to "Hide or Expose" as Nicolinux suggested just to be sure. I just printed it and the problem has been solved! Thank you guys.

Hello, I've been trying to print marvin. Although everything looks fine, I'm keep getting this z-scar (vertical line) on marvin's head. This has been consistent even after changing the setup to: 1. Increase printing temp to 210 2. Print Speed to 50mm/s 3. Fan speed 100% I'm not sure what else needs to be done to fix this problem. Please help!
