My Maslow still needs some mods before i can say something about precision. There is one frame setup which can make the maslow precise to 0.5mm (i think): Maslow Mark II - 3D
If you read the thread you can find an excel sheet with the precision reached at different areas.
May i ask which classic, gantry style CNC’s are close pricewise to the maslow?
cheers,
Arnd
