Last night I switched out my old computer for a fancy new one. This one has Windows 7 (32 bit) and a shiny new Rosewill RC-304 2-port parallel PCI card. After switching it over and trying the axis’s I found that it is 'stuttering' a bit. Not completely stopping but just slowing down randomly in spots on all axis’s. I'm sure I'm not the only one that has had this problem but from what I've read people are saying that there new parallel cards didn't put out a full 5 volts. The reason I went with this card is because I read here that this is a good one to use. Having 2 ports will either allow me to add more functionality to my machine or allow me to have my second machine connected to the same computer. Well, until this is worked out neither of those things are going to happen.
