I'm working on my second retrofit using kflop/kanalog. My first one makes obvious stepper sounds even though it's fitted with servo's. It also makes a screaming sound when the drives are in position for more than a few seconds.

I have 3 questions:

1. What should the "kernel speed " in machb3 be set to?

2. Is there a connection I should make to the "p-con" pin on the yaskawa drives to the kanalog board to put them to rest after they're in position?

3. Is there a better choice other than mach 3 for my new lathe retrofit?

Hi Dennis,

I'm working on my second retrofit using kflop/kanalog. My first one makes obvious stepper sounds even though it's fitted with servo's. It also makes a screaming sound when the drives are in position for more than a few seconds.

Seems like tuning issues. Post some Step Response Screen plots. Include some with Move Size 0 while making the "screaming sound"

What should the "kernel speed " in machb3 be set to?

That shouldn't matter the Mach3 kernel is not used. Set to a large value.

Is there a connection I should make to the "p-con" pin on the yaskawa drives to the kanalog board to put them to rest after they're in position?

No I don't think so.

Is there a better choice other than mach 3 for my new lathe retrofit?
