the bit-rate that the computer transfers information to your cutter has to match in THREE places:
1. in the Control Panel, open System, click the hardware tab, click the Device Manager button, and under Ports find your cutter. right click, and select properties. now click the port settings tab. look at what the Bits Per Second option is set to. mine was set to 19200. i find it worked best to use what the computer picks by default. remember that number.
2. on your cutters lcd screen, scroll through the settings to your baud setting. change it to what you found in the device manager, in this case, 19200. make sure it saved that setting by restarting the cutter and checking it.
3. In your project manager, when you select what cutter to use, right click on that, select cutter options or properties ( depending on what program you use) and make sure that the bit rate for your cutter matches the previous two.
once all these numbers matched up, it should work fine. although, every once in a while, one of those three numbers will change itself for no apparent reason. I havent figured that one out yet. Good luck man!
