I used this little linear regulator board with the Elite power supply and adjusted the output voltage to suit the laser pointer I had. One relay in the MASSO 6X relay board is mapped to turn on the pointer.

FWIW, I find the laser quite useful for setting or confirming X0,Y0 where, say, +/-2mm accuracy is enough.
