Hotend performance testing

I will be testing these 4 different hotend blocks under the same conditions:

  • Milled copper block with the Supervolcano adapter
  • SLM steel block with the Supervolcano adapter
  • SLM steel block, no adapter
  • SLM steel block, no adapter, small OR big brain internal geometry ☺

All of these have 50mm + V6 nozzle protrusion length melt zones, it'll be interesting to see how the flow rates compare. In order to seal the SLM melt zones I'll be using soft brass washers as gaskets.

With the current, somewhat flawed extruder design it can push around 60-70mm3/s sustained flow with a 17mm stepper and ~40V. I'm hoping to get it significantly higher because my previous, printed extruders could do a bit more with shorter melt zones.
