Hi Tweakie. Thanks for that.
Followed the Warp9 Laser install to the letter but didn't work.
Found that , for some reason, my system only recognises Port 2 for the M10/M11 commands even though the BOB is plugged into port 1 on the ESS.
Changed M11P1 to M11P2 and away it went.
Thanks again for your valuable time and assistance
Doug
