Actually I posted at teh beginning several times BUT the posts disappeared.    I though maybe you were trying to get ahead of me in posting so I waited until you jumped in and now my post stick.

HIYA Ian remember this is a 3d profile Cutting file not a flat 2.5d. It is really hard to get away from micro segmented lines and still have great detail in teh carving. 

AND YES if it works good now NO problems.

Yes but does it do BOTH anti dives or just one. The pause would be THC delay . The THC stays OFF for teh pause period to allow the torch arc to stablize after pierce. Then when it is stable and cutting the THC turns on. IT keeps teh torch from diving on pierce.

Dave I hear that Torch Diving will be an olympic sport next time (;-)

you program teh Gcode just as you described it being done.  You have 8 inched to move in 70 divisions so each divsional move in Y will be approx .1143". So you create a vertical column of Y values incrimenting by that value for each line. Next start at line 1 and add teh Z component to each line

G01 F100
N1 Y0.000 Z0.000
N2 Y.1143 Z.010
N3 Y.2286 Z .020

Etc
etc

That will cut your shape as a collection of straight line moves. Now you need to determene what teh bottom of teh cut is suppose to be such as flat radiused, circular . That will determene HOW it has to be cut. Either vertically or horizonally .

NOW IF you need a better shape than straight lines will give then you need to Draw it out in Cad and convert teh stright line segments into smooth arcs and then left CAM define teh arcs in Gcode.

AND YES IF you can do the math it can be DEfined in GcODE  using #VARS AND MATH STATEMENTS to define teh shape.

It just all depends, (;-) TP

It will work you just have to know where you start and stop rotations at so you can sync the A back in properly when you retract back to teh start. Yes it will save some time over  unwinding teh A each time.  Just be aware that somewhere or sometime you will have to unwind it (;-) or refhome the A again.

Tormach supports their OWN version of Mach3 you really need to talk to them.

Try something for me . In your script change the word False to true and remove te sleep or reduce it down to say sleep(20). That will check the logic state.

Push the reply button then select additional options. Then use browse to point to the file you want to upload. Double check the size of your pictures (;-) keep them small if you can.
