Re: [CAD_CAM_EDM_DRO] Re: ACE Converter anomaly, REDWOOD

Typical problem with wood. More spindle speed will help but won't
solve it entirely. But if you back up the cut with another piece of
material you can solve it almost completely. Note this piece will be
sacrificial but the cutter will move into it and it will support what
would splinter if you didn't have the backup piece there.
