Hi. There has been a change to VR Milling with a new release candidate to try please.
1. Stop any current Denford software.
2. Download the new installation from :www.denfordata.com/downloads/VR
Milling V5 CD-ROM.Candidate.zip
3. Unzip and install this installation. It should allow tool values greater than 8 in your gcode.
If this release candidate works then it will be released as the main installation.
