I have run a few very old Siemens controllers. the 1 I ran the most was a CC100. but that was a very basic controller. we had several older 1s than that , that had 5 LED lines . 1 for each axis X,Y,Z,A. and 1 semi longer line that showed code like the old yasnac g2000 control. I have a few Haas's at home , as well as being a haas tech for many moons. I have worked on the MX and LX 1,2,3. controls. have a KIA KT21 lathe. the newer yasnac controls ( I guess they would be old now) yasnac I80 . the Mitsubishi controllers.Fanuc O, 6, 10, and 15. Fadel nc88, and the 1 that had gibbs built into it ?? and a few other weird variations. Bosh, brown and Sharp, anilam, Bridgeport, for example . Just havent seen any of the new Siemens controllers til now. after we get things up and running I'll post some feedback. Thanks for the response!!
