I have problem with the feed-rate. The machine goes much slower than the G-code. Only 10-20%. It has been running good for many years, but now I got this problem. When I use the MPG it is also slower than normal. I have not done any uppdate lately. I run Windows XP. It seems lika there is a program that takes over the Parallell port, and slows down the speed of the pulses. The movment is correct, so i don´t lose any pulses, they just come at a slower rate than I expect. I run in wood. Normal feed-rate I use is 1000mm/min.
