Judging extrusion temperature from the shinyness

Recommended Posts

This post may relate to temperature problems within the Marlin 1.0.0 B1 firmware.

I started using the new Marlin, and so far it's great, other than the build in speed limit.

The picture above is printed/generated from a0.2mm profile in netfabb, printed at 225 deg, and max speed: 500% (300-500mm/sec?).

The first 35mm went perfect, the surface is really nice and shiny.

Then, suddenly at 35-44mm, the extrusion stalls, and looses it's shininess... the temp setting/reading is still the same (225), but the extrusion is forced, and gets a new surface:

a lot of fuzzy surface. Then between 44-52mm the extrusion becomes incomplete (no adherence, big holes etc), and the only way to bring it back is lowering the speed (back to 100%), from 52mm upwards. I tried increasing the speed back to 200%, but it also produced matte extrusion eventually.

Bernhard, let me know what additional info you need, if it is indeed FW related.

    • "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.
