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 just finished creating the Frankenstein and I bought this one:
v6 HotEnd Full Kit - 1.75mm Universal (with Bowden add-on) (12v)
Also, I bought an upgrade for my bowden drive:
Anycubic Left Hand Aluminum Frame Block for 3D Printer MK8 Extruder Reprap i3 DIY Kits
Just buy the right bowden drive or you will have to reverse the gearing.Lastly, the SkyNet3d Firmware Development Facebook Group has the firmware you will need. Makes the process so much easier.
