Unexpected realtime delay and genserkins

OK well that does pretty much prove that this is an issue with real-time and genserkins

It might be worth trying a RTAI version of LinuxCNC (perhaps a modified parallel port configuration)
to see if this is uspace related or a some other genserkins issue

Solved!

1. I installed www.linuxcnc.org/testing-stretch-rtpreempt/
No error when starting the G0 command!

2. I updated LCNC to 2.8
Error messages have become more informative.
Other error messages relate to the features of kinematics
Genserkins is not trivial in use!

Thanks for the help!
