3D probe from shopbot

What's the average time to probe a 12x12 object?

I'm assuming if something takes an hour or two to cut - then it must take days to scan..

Depends on the resolution you choose.
The short answer?
Feels like forever.

You probably don't want to go less than .025" stepover with a 1/16 stylus; .04" with an 1/8". It will probably take a day. Don't think cranking up the move speed will help...It scans at 1,1 best.

Scan as an SBP...not DXF...or you'll be scanning it again.

Safe enough to go to sleep and leave it running I assume - since the router is off

[Brady Watson]

I used to run mine for a week at a time. Sometimes it would fail...which sucked, but most of the time OK. The older probes were the best. You gotta check on it last thing...and then first thing in the AM.

I have a guy wanting to replicate a chair seat and its profile of where you sit so it matches the others - so I assume this should be sufficient for that

[Brady Watson]

Yes, as long as it isn't a cushion. The probe isn't sensitive enough not to compress the padding. For that you'd need non-contact.

If I'm only going to be using a 1/8" ballnose is the 1/16" probe pointless to use?

[Brady Watson]

If your intent is to cut 1:1 scale, then no on smooth parts.

If you are looking to scale up, or need higher resolution then you want to use the 1/16".

Regardless of probe tip used for 2D scanning, the resulting outline(s) will be offset half the probe diameter larger. You have to redraw it properly with splines anyway. Trace over it with fresh vectors and then offset outwards. Don't sample smaller than 0.5" resolution on the 2D or it'll fail by circling out...It will make sense if you don't understand it now.
