Just a quick question before I go spend a lot of money, when I had my machine serviced back in July I was told I was running approx 19 to 20 watts, I have a 25 watt machine..It has been running pretty good, a few items I had to lower the speed on I mostly run acyrlic..I was running some plastic signs, it was cutting through the black pretty good and white under layers was pretty clean but when I started to cut them out, there were 12 items the first 4 cut great, after that each one got worse by the time it hit the last one it was barely making a line you could even see and the last one nothing...I ended up having to run only two at a time they are only about 3"x2" bears and it took almost twenty minutes for two because I had to slow the machine down...I am sure I know the answer, but before I throw out 800.00 or 900.00 dollars I wanted to check with the experts because of course my salesman is going to yes that is what it is...I have a vanguard 2001, which are service my universal, 25 watts I was also wonder if the price they are quoting is right or pretty close...any help would be greatly appreciated....
