Hi David, just thought i would intoduce my self as it appears you have an electrox scriba, i worked in design for electrox for 18 years and had a hand in the scriba design, i now have ny own business using electrox lasers and we have 10 scribas, i see you are lucky enough to live in NZ, very pretty country, i have friends there and did a tour in a campavan 3 years ago all over the north and south island. If you need any hints or tips for the scriba let me know, i have lots of inside information, do you have a rotary for the unit, cheap to buy and fit now and you can engrave logos and text round parts, might open up new revenue streams for you. All the best in the rugby, might see you in the final. Matt
