Ultimaker 2 no longer purges material

Recommended Posts

After delaying a long time, I finally decided to upgrade to Cura 2.1.3

Problem is, now my extruder never works while printing, even on older Gcode files created with Cura 15.

I can still move the material through the control menu on the Ultimaker, but as soon as a I pick a GCODE file, the extruder never works. It skips the purge that it used to do at the beginning and immediately jumps into the print, but nothing every is extruded.

Please help

Edit: I've done a factory reset (no change). I've tried older files created in Cura 15 and they no longer extrude as well. I've switched materials (no change). Right now I have a printer that won't print anything, which sucks.

I assume you did a firmware upgrade?

Are you absolutely sure you did the upgrade for the correct machine? meaning if you have a ultimaker2, you did select that one in cura , and then did the upgrade?

A common mistake if people mixing the Ultimaker 2 and the Ultimaker2+

I would advise to check and do another firmware upgrade just to be sure.

I figured out the problem.

I was trying to print MakerGeek wax filament, which has a recommend temp of 150C. What I learned was any time the temperature was below 170C, the extruder stopped working.

I set my temp to 175C and was able to print the wax filament, but as a result of the extra heat, I didn't have very good luck in the part not curling.

Why did Ultimaker set the lower limit to 170C?

    • "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.
