kimalbanduscutter

Hi all ! great looking forum, I'm new to cutting, but I have used and setup plotters for years. I just bought a sc 25" cutter and could not get the cutter to cut correctly with the sc 25" driver.I spoke to signcut and they told me it was because I was using the usb printer cable and I had to buy a usb to sreial cable to correct issue. I'v tried this on win7/64bit and vista64bit. New cable - same problem. At certain points, the cutter was not lifting before moving to the next starting point. No problems with grounding, same error repeated in the same places every time. So I changed the driver to USC MH721 and it cuts fine! Any Ideas why the correct driver dose not lift when moving from end cut to next start point? Any ideas would be greatly appreciated. Kim I attached scans of the cut using the pen, same error when cutting.
