I also got the HardCore and the Everlast nozzle (Ruby, 0.6mm). Installing the core was smooth, next I had to calibrate XY offset. Then I was ready for a first test print. I loaded regular PLA and just set the line width to 0.55mm (to account for the 0.6mm nozzle). Everything worked as expected. I was amazed how fast this thing actually prints - much faster than with the original 0.4mm nozzle. I chose a layer height of 0.15mm. Apparently one can go up to the nozzle diameter (i.e. 0.6mm layer height). The print looks good. It's a bit less detailed in the XY plain due to the wider nozzle, but the result is quite good.
Next I wanted to try specialty filament, namely XT-CF20 from ColorFabb, a carbon-filled filament that prints at 240-270°C. When loading the filament I had to select a material type on the printer. I decided to pick PLA for now, but the core temperature was not high enough to melt the filament so it didn't load properly. I changed the material type to Nylon and went to Maintenance->Move to extrude filament. I still had rests of PLA in the nozzle and didn't want to burn it (3DSolex recommends to do a cold pull after every print, but that seems overkill). I pushed out the remaining PLA and some of the new filament while the core was still heating, then I was ready to go. In Cura I chose a printing temperature of 245°C, bed temperature of 65°C and a print speed of 40mm/s. Line with was 0.55mm again. I decided to go without any brim and it turned out I didn't need one. The nozzle oozed a little bit in the very beginning but that stopped after 30 seconds or so. The print went through successfully and looks quite good, however, the diagonal surface fill does not quite reach the walls. I guess I need to tune settings in Cura a bit. Any hints?
Due to the sapphire or the ruby tips on the nozzles, this makes the nozzle tips almost as tuff as diamonds, so it doesn't wear out due to very abrassive materials like Carbon-Fibre filaments, or prototype materials (which i do test sometimes).
Something like carbon-fibre can destroy the brass nozzle tip within 30-50 continious hours of printing. While this tip should allow you to keep on printing for probably a few hundered hours with abrasive materials. And if you print with only your standard filaments the nozzle could easily last you a few years, so they called it endless.
I Just tested the 0.2mm ruby nozzle, and the printer had no problems with it's active leveling.
In the next few days I'll try a small detailed print with it.Edited by Guest
