Some notes on our current 3D printing setup and where it could possibly go.
3 FDM printers (MP Select Mini v2, PS i3, MP Maker Ultimate (Wanhao D6))
SLA printer already has its own web interface- tends to change IP address on occasion,
One Pi 3 has been set up for Octoprint (via Octopi) connected to the Ultimate for now. Have a workflow going with Cura→ printer through Octoprint that seems decent.
Unfortunately, Octoprint only really directly supports one printer at a time (kind of lame, but I understand their reasons…)
We've actually done a fair bit of this - see Octoprint for more details.
