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 can look this up, but since you have already done it, I thought I'd ask.
How did you handle the X-zero stop being so far from the print bed in the Marlin firmware?
And, did you use the most current Marlin? (I have two or three older variants I use on my printers...)
