Make sure Flex cut fast changes the tool to #5 and Flex cut accurate is tool #6. You still need to either check or uncheck all of the options under "job options" otherwise it will force the default settings in flexi. (keep them checked if you enter your parameters in flexi or uncheck if you set all your parameters at the plotter. I use flex cut every day. If you have any issues you can send me a pm. I use Flexi 24 and a Summa S2 T160
