Three Vintage CarveWright CNC machines. First machine works well. Second machine worked well till I upgraded the bit holder to the new bit holder which will accept any regular 1/4” router bit. I replaced the z truck with new bearing and belts but now it starts but stops with a code. The third one is for parts. It was raised too far and got stuck. I will also include metal dust collector shoots. The price is or best offer. I bought a very large CNC machine and now need some room.
