I think that it is not as big of a deal, myself. I implemented rigid

expensive computations of feedrates. Plus I can post videos on youtube.

Well, that was possible because you retrofitted the machine,
of course.

Yep, and I am very happy.

Not sure if Eric is planning a retrofit. And, of course,
Mach does not do rigid tapping without a Galil card.

I am really glad that I did not use Mach3.

Greetings Iggy,
Why are you happy that you did not use Mach3? I have been considering
using Mach3 on a lathe conversion. I have seen a lathe running Mach3
threading parts and it seemed to work well.
Cheers,
Eric
IMHO, the call should be based on wheather you have steppers or
servos. Mach is a great stepper control but doesn't take position
feedback. EMC is slightly more complex to install and may be slightly
behind on ease of use, but it has ability to receive feedback from
encoders and drive servos directly.

Mach can be made to work with servos, and EMC can work with steppers.
So, if your heart is set on one control go for it.

Karl

Greetings Karl,
I have been using Gecko servo amps which close the loop themselves.
This means that the control software doesn't need to accept feedback
from the encoders. I haven't decided yet if this is a big
disadvantage. I think that in a low speed application it's just fine.
Eric
