Have Boss 9 with less than 200 total hrs. Looking for retrofit. | | I got a boss 9 from the local school district auction . It was still crated and never used. I have about 200 hrs on it playing with it for the last year. I do not know G-code. Looking for a retrofit?? Has anyone had good luck with one brand over another. Was looking at Centroid control will cost about 10 grand. it has all the bells and such. Just looking for any feedback . Thanks John |
