Does anyone know if it is possible to upgrade the sigmapro software on these machines to a newer version? We are running version 6.35.19 and it just really sucks. Is it possible to go up to say version 7 without upgrading any hardware on the machine? I want to ask Speedline MPM about upgrading software, but I know that they are going to try to sell me some vision cards or cameras or something really expensive. HELP?
