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!
