Hi Aaron - if the machine has a driver problem, changing the controller
to LinuxCNC isn't going to fix it. You will need to change the drives to
suit whatever controller you choose. If you have a working AXYZ
controller but bad drives, it's going to be cheaper, and far less
learning curve/time to replace the drives and stick with AXYZ, rather
than replace the drives and go LinuxCNC!
