Its a balancing act so if you are only upping the temperature to get higher flow but not the speeds to use that higher flow then there will be some issues. Each filament also has different temperature and flow characteristics so just because the new filament works with the current settings doesn’t mean the old filament was junk.
The volcano was made for high volume prints and has a bigger melt zone. Ideally it’s best for bigger nozzles, high layer hights and faster printing.
If you want to print small and detail a normal e3d or other hotend gives you better control. For smaller characters you can use a standard hotend with a 0.3mm nozzle and switch on arachnid or similar in your slicer. That will give you pretty good results provided your cooling is good.
For calibration its best to watch a few videos as its a lot to discuss over a post like this. But you are looking to do e-steps, flow-rate, temperature tower and retraction. Also know that this may change when you change the filament or speed you are printing at so try and keep things as consistent as possible.
To be honest the Volcano HE is the wrong thing for printing small detail like a DnD character. If you do all the calibrations it can print quite well but will never have the control thats needed for high detail prints. Your best bet is to have an extruder setup that makes it easy to change out the HE. I run both the volcano and normal E3D v6 and swop them out when needed with a EVA extruder.
There are some plugins you can try in octoprint.
Personally I would probably install cura engine or PrusaSlicer on the pi SSH in and use the CLI to slice the stl and upload the gcode. You can probably write a script that monitors a folder and runs a script to do it all when a stl is dropped as well.
Most brands should work fine. Same with hairspray.
I’ve been using glass print surfaces and glue stick for 10+ years. I just wash off the glass with warm water every 2-3 prints otherwise just add a new layer of glue stick before printing. I’m going to try a G10 print surface next as I finally found some in my country.
Thanks I’ll give that a try. I also found another post on here about the Manifold engine that’s way faster. Its only in the dev releases at the moment and the under preferences/features/manifold
I bounce around between FreeCAD and OpenSCAD but I started on Sketchup.
Fusion is a very long term goal and I’m sure they are careful to not tarnish its image. But yes sadly the first commercial fusion reactors probably won’t be sustainable but once they are a reality investment into the technology will be much greater and hopefully cleaner fuels will become a reality.
