Linux
From Dynomotion
KMotion Motion Libraries are fully supported under Microsoft Windows. Some Users have ported the KMotion Libraries to Linux. Dynomotion will offer support where possible but can't offer full support under Linux. Special Thanks to Par Hansson for the initial Linux Port.
Note that the Libraries have been Ported to Native Linux which allow User Native Linux Apps to perform Motion. However the KMotion.exe, KMotionCNC, and other example Windows GUI Apps have not been ported to Linux.
