Re: Deskncrt

Thanks for the replies,
Yes I'm using the G320's Mariss, I know about encoder feedback in
hardware, just didn't understand why deskncrt would require tuning
when running in open loop.

Tim, can I setup EMC as open loop and run G320's (servo's). Can Dos
(Cncpro) still boot up if needed?

So many questions,...... so little time.

Any docs on the subject ?
