The tape is also like $20 a roll, I realize this pales in comparison to even medium tier wood, but was sorta immediately off putting for me since it reminded me of all the stuff with inkjet printers.

I wonder why not use those simple laser rangefinder things and instruct the user to put CD-tracking like servo steering suitable retroreflectors at fixed-relative-to-workpiece locations. 2 should suffice for planar work.

Probably "tape money" reasons for that engineering trade-off...

Sounds much harder and expensive than tracking points close by
Fyi It's possible to generate and print your own tape
