V0.6.0 Alpha Released!

Download V0.6.0 Alpha Now!

Hello! We’ve got a huge update for Pathio today complete with a large suite of bug fixes and a new feature!


  1. Very large models will still not slice. (The fix for this is imminent.)
  2. Models that have errors might report track ordering optimization failure when slicing. This means that the ordering of tracks on a given layer might not be 100% perfect, but it should still print ok.

Manual Supports

We’re happy to be announcing an all-new way of defining where supports are placed on your model: painting! More intuitive than adding modifier meshes and less tedious than repeatedly left-clicking on support pillars, painting lets you pick exactly where you want supports to go in no time at all. This has been the number one request for Pathio so we’re very eager to hear what you think of the workflow.

Major Slicing Bug Fixes

We’ve completed round two of resolving the various problems with slicing different models. If you’ve had trouble before with a particular model giving you problems in Pathio try it again with V0.6.0 and it should work. We can’t wait to see what everyone slices now!

Small Ram Improvements

We’ve started work on optimizing Pathio’s ram usage. You should notice it does better at releasing ram after a slice finishes (more improvements are on their way).


We would also really like to thank everybody who contributed to the discussion regarding

We need your help: Manual supports as the feedback and comments were instrumental in the development of the manual support feature.
