How to setup a 4axis gantry plasma machine using gmoccapy?

andypught:If your OS is Wheezy and your Relatime is PREEMPT-RT then the version you want is "Wheezy (uspace: realtime with RT-Preempt, and simulation)"
Are you actually using a Mesa Ethernet card, though?


My OS is Wheezy and my realtime kernel is the preempt-rt-as rodw suggested- I have installed linuxcnc-dev-uspace from apt.now the Lcnc version is 2.7.8.The max jitter is too high now and I can't upgrade my PC.
I don't use any mesa cards.

Shall I install the RTAI kernel instead of the preemptive kernel for driving the 4axis gantry X Y Y Z A? Or just keep the current kernel install?

Roll back to the normal Wheezy live CD distro and install master to get the gantry features.

Thanks for paying attention rodw. I'll make a new install and tell you the results.

Sorry you wasted your time. In my original post, I did say

No problem.I have learned from your post and andy's post.Also, I have learned how to customize the installation (minimal display server, minimal desktop manager, minimal window manager, grub themes, apt sources.list, kernel install and isolcpus). Thank you for sharing your time.
