Yet more frustration!!!!

I have just been into my workshop to have another try. This time I was cutting 1mm thick card and acrylic. Both times I cut through the card and acrylic but the machine was going very very slowly. It didn't seem to make any difference if I changed the speed setting it still went at the same speed!!!
I  am going to email jclingke.com and I don't suppose I will get a reply but its worth a try.
More to follow!
