I was looking into buying a CNC router for making small signs. I have been looking at CAMaster Stinger 2 or Computerized cutters Accu-cut KR. I'm open to others, but I was led to these companies by a friend and reading I've done here. The size I was looking for (due to budget) is 48" x 36" or 48" x 48" so I can fit plywood onto it. I was offered a used Gerber AR400 for $2k (48" x 27") but would need to buy software. Seems OK for a newbie and would save money up front but with what I've learned about it so far is I've heard you have to use Artpath for the software and import files to it for cutting. I have Corel Draw X5 I could use for some artwork but I think I would need something for 3D work. I can't find any information on this model due to its age so any input on this subject would help. I'm concerned that the money I save up front on this one might come back and haunt me later.
