I have been lurking and browsing for a bit trying to absorb as much as I can before starting my build. I am wanting to build an Eustathios machine.
If you could indulge me in a few questions, I would appreciate your time.
- Extruders- I am going to be moving up from a Wanhao Di3, so all I know is a direct drive extruder. I understand the Bowden type, and all of the drawbacks of the bowden type seem to be centered around the constraint of the filament in the guide tube.
To me its no different than a MIG welding gun-- for aluminum you either use a spool gun (much like a direct drive extruder) or a push-pull system like a Cobramatic. That overcame the limitations of soft aluminum weld wire- something very much like trying to print TPU, or trying to push a cooked noodle in a tube.
Has anyone thought to try a 2 motor extruder setup? To keep the weight low on the carriage, a small NEMA8 type motor could give the filament just enough ‘oomph’ to get through to the nozzle or back out while the NEMA17 at the spool would do the heavy lifting. We should be able to split the motor drive output to 2 motors like the less expensive i3 clones do for Z axis.
Electronics- Do we really need the 32bit boards? Can you get by with a 8bit RAMPS? My build may take a little while and who knows what the next latest/greatest will be coming out.
Has anyone tried using LinuxEMC to drive one of these pritners? A MESA 5i25 buffered I/O card seems to already do what the 32bit boards do.
Name- does anyone know why Jason named the printer Eustathios? I have not seen anything referencing the origins of the name.
