Drill cycle tricks....

Dudes,

Didja know you can specify coord shifts within a drill cycle? Yes indeedy.

There's only one pro'leng: Upon specifying G52, it seems that the cycle wants to drill the last hole twice, before making the coordinate shift.

Examples from my overly-complicated vise jaw program (which takes me longer to figger out how to use it each time, than it does to make the fukn jaws):

This is for the kurt vise, whose holes are 3.875 c-c, but two of them, for those long jaws I was posting about.

N49M6T2( 1/2 DRILL, STUBBY

N50L101( various coordinates'n'shit, incl. data for making the holes ovals

N51#R1=V10/2' X ( actually 3.875/2

N52#R8=8.5( actually 17" between sets of holes: E1 is at geo center

N53G52X-R8Y0( for the left hand vise holes

N54G0X+R1Y0Z2.H2E1

N55M3S1500( I just lernt to sep this out from Line 54, from someone's sample code post, as it's now easy to slash out, for dry runs without the spindle -- saves effing air, yo.

N56Z1.

N57Z0.1

N58G83G98R+0.1Z-1.2F12.1Q0.5L0( usually put L0

N59L301( executes the first pair of holes, lh vise

N60G52X+R8Y0( coord shift for second pair of holes

N61L301( second pair of holes, rh vise

N62G80

---------------

OK, fine'n'dandy, except Line 60 causes one hole to be drilled twice. At least on fadal CS-88 controls.

How to fix?

Another L0 on line N60!!!!! To wit:

N58G83 ... . . . . . . . . . . . L0 N59L301 N60G52X+R8Y0L0 N61L301 N62G80

Muthafucka!!! Voila!

For cadcamless assholes, coordinate shifts within a cycle argerment can make things pretty convenient, saves some code, etc. Now it's nice not to have holes drilled goddamm twice.

Try sticking in an L0 or L1 at the last position at the end of the line(or the equivalent code). Might force it to drill only once.
