I struggle making curved templates using the normal methods, ie. bandsaw, sanding, re-sanding and then having to start over when I screw it up.   [scared]. I can really see how this could simplify things greatly. I just need to figure out the right SVG software program to use.  I suppose I could take the measurements of an existing template and duplicate it digitally.  Would be curious if it can truly replace the Leigh dovetail jigs I have.

Great thread...
like the OP, I too wondered about true tolerances.
Now granted, not everyone needs tight tolerances.  When making signage, who cares about .001"?  But a previous poster dismissed this too quickly, as is often the case when tolerances are discussed in ww terms, using the common response "wood moves more than that".  But my issue is, wood moves the same regardless of the tolerance of the CNC ;)

This thread did a GREAT job at demonstrating some of the SO true uniqueness vs. stationary CNC, no footprint when not in use, can bring to job site, can match the work size of 4x8 CNC Gantry at a tiny fraction of the price, relatively simple software, tolerances good enough for prob. 98+% of ww CNC tasks.  (joinery excluded)

The potential downsides, which is still not so clear, tolerances for joinery and tolerances over long runs, user fatigue for extended use, user control error.  I appreciated the user input offered in these areas.  I can see how long repetitive work over large distances the SO becomes less desirable, as labor cost and fatigue and user error might creep in vs. stationary CNC.  But I think SO is not going after that market sector.

On one side, you see this perfect joinery being made on their videos, which demand super tight tolerances.  Heck, even with the Leigh jigs, we are adjusting our elliptical bushings in .001" increments to get perfect joints.   And yet the magazine article demonstrated tolerances way less than what one would expect for perfect joinery. 

Now that the joinery accessory is being shipped, I would suspect a lot of users will now be doing lots of dovetail and box joints, should be interesting to get feedback from those users, as if there is tolerance issues, they would surely surface with complex joinery layout, specially over long distances, such as 24" long.   I wold be quite impressed if SO can produce 24" long dovetial joints with perfect fits like shown on their website.  If it can pass that test, KUDOS to SO!!!  I am probably a buyer soon as well....

By no means am I knocking this product.  IMO, the premise and execution has been absolutely BRILLIANT, and I have been so impressed watching this company grow.  Love to see this level of technology brought to ww.  But like all posts on this forum, users dig deeper than current info is available. 

As a side note, I noticed smaller sized CNC, at about 2ft x 4ft range ($6K price range usa) state tolerances of .005" as a reference.   For non joinery work, I would consider this excellent.

WillB - you mentioned that even with a Leigh jig you are adjusting bushings to get that last .001" when fitting joints.
I haven't used it yet, but noticed that the ShaperO has a cut offset that you can adjust.  Pretty sure they use a similar principle that you'd find with the bearing adjustment for Leigh or the click settings with an Incra setup.
