Here is a copy of an answer for another question but it applies here.
As for other CNC machines, we need to be very careful. ShopBot is unique in that they really understand the underlying technology. They build and program their own control and have a deep understanding of how all this technology works. They are much like us other than they target a different part of the market making it a good fit. This can’t be said for most other machines. Some well known machine manufacturers don’t have a clue how their control works. I’ve seen some who don’t even have a control or software person on staff, they use outside consultants. An efficient, effective link with someone like ShopBot is easy. Trying to do the same thing with some of the others would be a nightmare. Just ask some of the other software companies about their ongoing problems trying to interface with these machines. We are going to be very, very careful. Also, the ShopBot user group is a lot like the Thermwood/eCabinet Systems folks. They seem to be very innovative and enthusiastic and should be a good fit.
