Re: [CAD_CAM_EDM_DRO] Question Re: Work Offsets

IIRC the 'accepted' procedure (assuming that Z0.0 is top of workpiece) was
to G0 X0.0 Y0.0 Z0.1, followed by a G01 Z0.0 Fn.n, so the E.M. would never
'crash' into the workpiece. Doesn't your software have a " set new home'
command. My old SHARNOA uses G92 for what they call 'Zero-shift'. Simply,
where ever you are, issuing a G92 will make that X/Y/Z be a new 'home'
position. Use as many times as you want, and G99 lets you revert back to
the initial HOME position. It's great for programming multiple parts in a
loop, each time resetting the X0,Y0,Z0
