Bad extruding (Tiny line - normal line)

Recommended Posts

It's probably slipping in the feeder. The feeder is pretty powerful - about 5kg of force normally. So for it to slip implies very heavy friction in the bowden or pressure in the head.

I recommend installing the IRobertI feeder only if it helps you feel the pressure and feed by hand so you have an idea of the forces and the friction. But this is not the fastest way to fix it.

It could be your problem is that the filament is 3mm filament instead of 2.85mm. 3mm filament will get stuck in the tube.

More likely you are just printing too cold and too fast. By default the bottom layer is much thicker - .3mm - so you have to print it hotter and/or slower. For bottom layer here is max print speeds for each temp. Just try increasing the temp in the TUNE menu to 240C and cutting the speed in half. Just for the bottom layer.

Max recommended speeds for a given temp when layer height is .3mm:

14mm/sec at 200C

20mm/sec at 210C

27mm/sec at 225C

33mm/sec at 240C

    • "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.
