QTPlasmaC with fourth axis - rotary

I am going to ask the question about putting cash towards the problem as it influences a lot of users at the moment.

linucnc is great but for sure we need to solve these problems in the near future, I think a lot of people including me are willing to donate.

I have started a discussion on the email lists. Lets see what comes of it.

While the slow down is not ideal, in practice it may not be as big an issue as you think. I have quite a few customers running CommandCNC (mostly stock LinuxCNC with a custom front end) with rotary and haven't heard many complaints.
