I have 4-s axis on my linuxncnc machine. When it starts to work, all movement's become very slow and configuring speed with G1 Fxxx doesn't help's me. I've looked topics with such my problem and found that problem is that speed configuration changes from mm/min to deg/min. But I realy didn't anderstend, why axis not become faster when I change feedrate.
What regulates speed when works rotary axis? And how to control it?

There is a LinuxCNC filter here:
forum.linuxcnc.org/38-general-linuxcnc-q...r-me?start=10#120524
That converts to G93 mode for XYUV motion. This is close to what is needed for rotary motion, but different calculations would be needed for rotary axis work. (Exactly the same calculations as done by the rapid-roatary app linked above)

You might need to give the file execute privileges,

Do a google search on how to fix file permissions in linux, but do be careful, there are a lot of things that can be messed up with that.
