Re: [CAD_CAM_EDM_DRO] Question about angular and linear feedrates

My controller software does this move in 30 seconds, and I just wanted to
know if it was like that for all controllers. I also think that it should
be 180 seconds, but has anybody done this test on their machines. For
reference, I am using TurboCNC v3.1.
