Three Carvewrtght CNC machines. One works well. Second worked well till I upgraded the bit holder to the new Carve Tight bit holder. Now it starts but stops and shows a code. I bought a full sized big CNC machine. Now I need the room. The third machine is for spare parts. I will include two metal dust collectors up grades. Price is or best offer. I learned about CNC on these machines. Sure was fun but I’m need the room and these need a new home.
