Re: [CAD_CAM_EDM_DRO] Ball screws

I've seen them advertised but really have no practical knowledge of
Kerks lead screw. Kerk actually makes lots of different lead screw
assemblies so I wouldn't be surprised if they had something new. A
talk with an applications engineer may help.

As to lead your CNC coftware would have to compensate in some manner or
form as even if the lead is constant the encoders and the gearing are
likely to be different form machine to machine. Not a user of mach2
either so specifics can't be offered at this time. Generally you have
a way to specify counts per inch/mm someplace within the software.

Thanks
