Your image looks great Tweakie, So here's what I will do, I read the article on setting up the laser settings in the ESS. Looks fairly straight forward so I will do that today. I'l l then add your PP. I shall purchase Aspires add on for creating laser work, images cutouts etc and try it.
It is my feeling that Aspire have written pp's for direct download to half a dozen different machines, bespoke machines are not supported, this I understand. I cannot see why it wont work going through a Mach4 PP such as yours.
It looks to be very good piece of software so I'll try it. For the sake of 40 quid, well.....
