I am running a Biesse Rover G5.12 and use Biesseworks. I'm trying to put a tapered dado on a piece of 3/4 MDF but the software does not seem to have tapering options for Z axis. I have tried to alter the G-code but the post processor throws out the changes. Any recommendations? I need one end at zero and a tapered dado of 1" wide all the way down the X axis to approx. 1/16" depth. Thanks
