Fun and games. Trying to make mill factional

[JAZZCNC]

I would of liked to go closed loop, but the cs-labs controller can play up at times using a closed loop system.

Who's told you that load of rubbish.?

The Cslabs controller knows nothing about what drives it controls, that goes for closed-loop stepper drives or Servo drives. All it does is send out pulses to the drives after that it knows nothing about the position or even whether the pulses were received.
The closed-loop portion of the stepper system is solely kept between the drive and the motor and nothing gets fed back to the CSlabs controller, the only part it plays is producing the pulses and to that end, it doesn't know or care what receives them.

I have built dozens of machines with Cslab controllers and closed-loop steppers and I can tell you with 100% certainty that it works perfectly fine with them.

Hi jazz, I fitted a closed loop motor and driver to my last machine, and it did not like it. It may of been that I only used it on one axis. But it could of been me. However I have read on a few forums that people have had a few problems. I think if ever I get this mill working as it should I will fit closed loop on all axis.

Hi Terry, I can assure you 100% that the Cslabs or any other open-loop Step/Dir controller for that matter knows nothing about the drive which is attached, they just send out pulses and trust the drive receives them. Now, you can get drives that handle pulses timings differently but I've yet to see a Closed-loop drive or any drive for that matter that doesn't work with the Cslabs controller. However, pulse timing issues can usually be dealt with in the control software motor tuning.
