Vectric Aspire makes a mess of a circle?

Does using a external motion controller make any difference - is the jerking only when using parallel port?

Why do you use FRO at 300%?

Program the feed closer and just go up to 70 or 80%.

Most professional controllers won't allow more than 100%

This is with a motion controller, UC100

As i said, i was only doing a dry run so speed was irrelevant, in reality I have never used FRO or SSO !

Why do you use FRO at 300%?

I would normally adjust feed rate to the middle of the green in CAM but it was a one-off job profiling a couple of small ally plates with a new single flute cutter, I realised it could run faster once I started the job so I just wound it up until it felt right rather than going back to CAM.

Yes, I mentioned it in my previous post.
