Awl --
'member dat loooong manual contouring thread, where I posted some spreadsheet techniques for manual contouring using variables and passed parameters'n'shit? The one where it turned out that jb dint know how to contour OR use a spreadsheet?? When he ran off like a gerl???
I think Garlic started that thread with a very inneresting article ca 1985 on manual contouring.
Well, truth be told, I didn't read all I proly should have, as I looked at the pitchers, basically grokked what was going on (I thought), as it seemed similar to other stuff I was doing/had done, and read some/skimmed some.
Well, ahm lookin at a simple part here, figgering I no need no stinkin fadal CRC here, and it turns out.... Goddamm, I never *really* mimiced crc manually the way I thought I had!! Altho it seemed I was able to slick my way *around it* often enough. But never truly mimiced it, it seems.
And, of course I would cave in and use crc whenever the going got really tough. I apparently did not realize just *how quickly* things get tough!!!
So I got a part here, which has a bit of an octagon thing goin on, ostensibly no real need for crc, and as I tried to go around the first corner, it hit me: Man, I gotta go through *all this bullshit* just to go around a goddamm non-90 deg corner????
Wow....
And for the first time, I now *really* understand the diff between M96 and M97 (iirc), and see that if you are manually contouring, it seems to be actually easier to roll around a corner than to not roll. Ie, clearing the corner until you hit the new toopath for the next angled edge is a worse picnic. But with rolling you still gotta calc. the exact end point on the arc.....
For 90 deg, both ways are simple (non-rolling actually simpler for 90's), but for anything else, goodgawd, you really gotta calculate yer ass off. If not rolling around the corner, you gotta calc all kinds of parallel and perpendicular lines'n'shit, with intersections! I think.....
So ahm thinkin, mebbe someone can post that link again!!!! Or mebbe, if manual contouring is really this much of a pita, just fugit, and use the crc.
The lesson I think I've lernt here is, Yo, anything other than 90 degrees: CRC IT!!!!
Does anyone else put up The Good Fight to avoid CRC, and if so, at what point do YOU cave in??? :)
