Tried tonight and results were worse than expected. It would not go past first heart. Also it would randomly start at 0 or -10 on the z. Restarting Mach 3 will make it start at 0.

G-Code, CAD, and CAM discussions / loops in loops

I’m trying to cut multiple hearts on the same metal sheet. I omitted the part of the code that works ok. Getting a loop within a loop seems to be the challenge.


M98 P2 L4      (Main program calls for O2 to move axis 5 times)
M0



O2         (moves axis to different part of sheet to carve heart)
M98 P1 L32        (Calls O1 to cut heart in 0.1mm increments through ¼”metal)
#2=[#2-38]      (advances axis counter)
G52  Y#2      (moves axis to next heart in line)
M99

#1= -0.1
O1         (sub for carving hearts)
Bunch of lines of gcode that inscribe heart 
#1=[#1-.01]      (advances depth by 0.1mm increments)
M99

When I do this, the tool path generator will outline the number of hearts along the y axis but will not move beyond cutting the first. Help,valentines day is soon and I have three daughters.
