Re:Gcode

Ballendo,

I'm surprised on the DLX, since it's advertised as 4-axis, but that's
why I asked. No use spending more money for an update, if G18 & G19 are
missing. Is Otto in the US? I had the impression that MAXNC software
might have been written in another country. Not to be negative, but
just the impression I got from some of the key command selections. Easy
enough to learn to navigate it, 'tho. And the price with steppers,
drivers and software was cheap enough. Well, almost.

You mean S&D to phase? Yeah, I can do that. Can probably use the old
schematic I had before. I've done it with 7474 & 7486 as I recall, and
even state machines in PAL's. Just have to sit down and do it. I've
got a MAXNC PRO S&D waiting for them and 4 SD200 drivers. Might need
some motors.

I did enjoy getting a handle on the arcs in the other planes. Also made
it easier to draw!
