@EvanSmith Yes, I have Linuxcnc configured and working on the X-Carve. I did have to change from the IBM Think-center that I was going to use as it’s latency figures were bad. I ended using a HP system of about the same vintage which gave excellent results.
I’m running Linuxcnc 2.7.3 (the latest) on Ubuntu 12.04.5 LTS. It’s running a Gecko G540 with the A axis slaved for the second Y axis motor. Motor direction may differ depending on how your motors are wired. Home switches are wired normally closed and all are connected in series to a single input pin. (I may change this to be the same as the X-Carve i.e. separate connections for each home switch, so I also run the system with an Arduino controller - one day)
Here are the config files I’m using x-carve.zip (7.0 KB)
You may have to tweak the stepconf file to suit the results from your own latency tests.
