Just a follow up on this--I was working on a project last night (kinda neat--a customer wanted a vise for holding little blanks for those brass stamps you use to wax seal envelopes and I was machining a set of vise jaws for holding round objects)...and I was almost done with the job when I got the "waiting for fabmo..." I power cycled the tool but had lost my position, pretty much means I have to start over because I'm never going to get it realigned perfectly and I wanted these aluminum parts to look sharp.
I know that I have a pretty shoddy wifi network in the back of my shop and I wondered if that might be causing problems. It should be just fine..because the tool doesn't need to communicate during a cut, the file is totally contained in the handibot...but I went to AP mode just in case...and re-ran the file. Had no problems, and got all the way through.
I saved a log out to pass along to software guys, hopefully to figure out what caused the tool to panic and interrupt my job. It's something that we're going to get to the bottom of...in the meantime though, I just wanted to let anyone know that AP mode can be very stable in the absence of a reliable wifi network.
