Hit the try topic in section you want, in this case its might be "General Electronics" board.
lets see what happens than we may creat new board for it.
Maybe a good time to try this again, most CNC posts look out of place where they are now.
They need a new home.
The number of members who use CNC is also growing, I would add 3d printing to the same forum / board.
At this time, there is no where to ask advice on CNC or 3d printers / be it making or using.
for example setting spindle speed, and feed rate, for different materials like plastic or aluminium.
