It seems to have worked out pretty well for the 6 people that designed this one ! ( Though a million dollars doesn't last that long these days !  :laugh2: )

Ha!  Good point.

And figure for Kickstarter themselves they all work out just fine as long as they make their funding goal - since they get their percentage as soon as funding is reached no matter what happens after that ! (kickstarter gets 5% of the total and their payment processing company (Stripe) gets another 5% on every project that reaches it's goal !) - So they have no incentive to change anything !

it takes a good deal of force to push a router through wood. I'm not sure how those wheels get enough traction to overcome the force while maintaining accuracy.
it also takes a good amount of force to maintain a straight cut while the router wants to steer in the direction of bit rotation. Everything tells me this device won't work, but I'd love to be proven wrong.

michelevit:
How do the wheels navigate over previously cut areas? I have so many questions.

Mike A:
It doesn't work. They burned through a million dollars of other moron's money and have not shipped anything.

Arroyo:
My bad on the pricing, over looked that bit, JDFAN is correct.

Definitely not going to do the kickstarter, but I'm also not going to write it off before it comes out.  Opendesk seems to think it's legit as they wrote an extensive article on it:
https://www.opendesk.cc/blog/goliath-cnc-a-robotic-tool-for-every-workshop

I'm just dreaming of the day when I can setup a machine from doing the work on a CAD program and come back a few hours later and everything's cut out.  Maybe this is it, maybe it isn't :dunno

They do address the issues with previously cut grooves and sawdust buildup on the kickstarter page and on the Opendesk article, and supposedly it's not an issue:

"Thanks to radio frequency communication, the sensors continuously update the position of Goliath relative to the work area, 100 times a second. This feature ensures the target accuracy of 0.1 mm (0.004 inch)"

"The omnidirectional three-module wheel design, ensures that two rollers are always in contact with the panel. In so doing, Goliath's movement isn’t affected by grooves or profiles that have already been cut, because at least one roller is always in contact with the panel."

The majority of dust and debris is pushed aside or rolled over by Goliath's omnidirectional wheels.

We have put Goliath CNC through testing to confirm that this does not affect the precision of the robot."


For this hobby cutting a 6ft+ height panel on a home CNC as far as I can tell would be $5,000+ on a traditional CNC bed so even if it's half the price and does a really good job seems interesting to me.  Maybe it's a flop, maybe not, but got me excited.....
