Hi!

How do I increase the motion buffer ahead time with pokeys57U?

HI,
motion buffer in PoKeys is static. What is the reason you want to increase it?

Hi!

I'm building small router with dc servos.

App. half of movement errors I'm getting are false alarms and I'm getting a feeling it might be some sort of comm delay at least behavior is the
same as with Kflops when buffer time is set too low. Difference is that KFlop says "Unexpected motion buffer starvation" but pokeys does not say anything.


I have previously built 4 machines with KFlop boards but they are too expensive for this project so I figured I try pokeys.

The Kflops have user adjustable buffer time and it has been useful in getting the machines run trouble free. looking around I found that also other
more expensive controllers (Galil & vital systems) have user adjustable buffers.
