Under extruding only on the back of the buildplate

Recommended Posts

I have 2 Ultimaker2+ machines, lately they both have been under-extruding when printing toward the back 4inches of the machine. (positive Y axis ). When the machines are printing toward the front (negative Y axis) the print quality is wonderful. I have tried: adjusting the feeder tension, temperature, speed, replaced the bowden tube, lubricated the filament with vegetable oil and increased the extrusion multiplier with no significant improvement of the print quality. I use Simplify3D application for generating the machine code. Any idea what would be causing this?

How does the bend of your bowden tube look when the printhead is towards the back of the machine vs. when it is in front?

Could it be that the bowden is a bit too long and has a bigger bend in that position causing more friction?

Dosn't explain why it would happen suddenly with otherwise well functioning machines though...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
