Subject: Close loop control between Mach3 and Kflop
Hi TK,

I have some questions regarding to close loop control under Mach3 and Kflop, could you please help to clarify.

1. I saw that, there is a encoder input inside Mach 3, I think it is for close loop control of step motor or servo motor. But what happen if I use Kflop and mach3 plug-in?
2. Is the close loop control only happen between kflop and motor? It is still open loop between mach3 and Kflop, right?
3. Is there any way to feedback the encoder information back to mach3 and make the whole system become a close loop system?


Best regards,
Benny.

Hi Benny,
 
Regarding:
 
#1 No Mach3 itself doesn't provide for any form of closed loop with encoders.  It can only display the encoder position and possibly halt on an excessive following error. 
#2,3 Well yes, KFlop will close the motor/encoder position loop.  The encoder position is also passed back to Mach3 for display purposes, but Mach3 doesn't (and really can't) do anything with it because it doesn't run in real time.
