Re: [CAD_CAM_EDM_DRO] Re: Software for wire EDM control?

Hi Dan,

That doesn't sound too hard. Your hardware then has a current sense
module, that sends a logic level to the controller program? Sounds like
a PROBE switch check.

How fast do the axis move for wire EDM? If they're slow enough, one
wouldn't have to decelerate, just stop immediately, and take some *back
steps* (sounds like a SciFi TV show a few years back). And the "back
step" adjustment sounds like what one does for backlash.

Yeah, that doesn't sound too hard. Now about calculating a PAIR of 2D
coordinated axis...
