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.
the gcode and .3mf i posted at the prusa site prints the track at 0.2mm layer height as some people's printers yield good tracks at 0.3mm and some do not. sounds like you are in the "does not" category... : )
please let me know of the TPU rewinds acceptably with the lower friction track.
I will look into adding a small slot at the bottom of the channel for the next stand iteration.
