Hi Ghanshyam, you can ask Masso support for a Masso update "Plasma v3.40.20pre" you need to give them your controller number so they can email you the correct one.
Sheetcam works well with the plasma to make your g-codes,
But as for myself and other people we are having trouble with THC issues, best wait till one of us can advise on the best way to go with that.
And for routing you will need the Masso Mill software, so you will have to speak to Masso about that as well.
Good luck with your CNC projects from Ross.
