MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I like the idea of the arm sensing the syringe, ill eventually add it as an update, once everything is running properly.
Considering the stall sensing, check out the stallGuard2 option of Trinamics TMC2130! Its a nice feature, although my number one priority is getting the basic setup running.
