I'm still researching but have decided on several elements to the CNC I'll be building soon. I'm going with the David Steele plan (25x37), the Xylotex 269oz kit, and the Mach 3 software. To get the optimum performance with these ingredients, which router would be the best choice? Brand wise I would like to go with either a Porter Cable or Bosch, just not sure which model/brand would be better. I'll primarily be carving/engraving wood and plastic. Thanks for any information.
