Based on the Sieg CNC pdf file, the KC6 will run on a Siemens controller presently.
However, I can confirm that Mach3 will definitely run on the KC6 with stepper/servo motors. In fact, I have a KC6 unit under test and it is working under Mach3. I just need to work on the 4-position auto turret tool post macro or brain. I am almost through with the electronic circuit board to control the turret but still struggling with the brain and/or macro (Hint: Maybe someone want to help on this
).
The spindle comes with an encoder though I am only using the index pulse for synchronization to cut thread. When the smoothstepper hits the market, it should be able to fully utilize the encoder.
When I have everything setup and running, I will try to post more details.
