AFAIK Mach3 is only good for step/dir control signal and forget about any feedback from servos there. Not to mention 2 feedback devices for one motor, where LinuxCNC has working examples.
Mesa hardware works beautifully with LinuxCNC, but Mach3 will not work with it - it works either with software stepgen through lpt port breakout boards (no EPP mode hardware with FPGA chips there as well) or with some USB motion control cards, and since USB is not working in realtime, USB by definition is not compatible with LinuxCNC. It looks to me that only way to have dual-cnc setup is to have open-loop (for cnc controller) step/dir system with software generated step signals and feedback loop closed in servo drive. My apologies, if I seem arrogant, but, based on the description of what hardware You have, I do not understand, why do You even consider Mach3, when there is LinuxCNC. Please, do not answer (unless in private email), because it will start another discussion :)) -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto 2013/1/3 Bruce Klawiter <[email protected]>: > Is there hardware out there that would allow me to convert my Mill to run > both LinuxCNC and Mach3.
