Thanks for keeping us posted eaddesigns.
I'll have to consider 2 failures that quick to be a pretty good indication of a lack of suitability, but can you let us know how hard were you pushing it? Did you rout some signfoam? Did it do that ok?
Deb, I was pretty impressed with Empy's 4x8 shopbot that day too, & last October I visited Raymond Chapman & checked out his brand new Shopbot... but what do you mean extra $3K ?
I guess you were referring to Shopbot's benchtop model? Even for that, I think to be realistic, you should set your sights on paying a lot more then $5K to include software, freight, and set-up with training, as well as upgrading a few of the more basic componants.
