Linuxcnc doesn't actually support the beaglebone. It was supported for a while on a branch that was not and will not be merged. It may be that you are using that old branch of linuxcnc or you may in fact be using machinekit (a fork of linuxcnc) that does support the beaglebone. That said if the beaglebone driver supports velocity step mode then it would be easy to add a stepper as a spindle drive. Let us know what fork of linuxcnc you are using and we can direct you to the best info.
