Hi I am trying to create a g code program with variables. I am very new to this and wanted to try to create a custom drill program. I'm sure it is wrong but wanted to post it here so people could see and help me fix it. I didn't include a G65 macro call but just variable assignments and an attempt at a loop. I'm trying to drill .5 deep at a certain speed/feed, remain in hole (dwell), then continue drilling hole hole at another speed/feed. I want to be able to do this to multiple holes like a canned cycle. Here's my attempted code...**The G91 X1 is to move 1 inch to next hole location**


%
O0001(HOLE DRILL LOOP)
#1=-.5
#2=-1.0
#3=1000
#4=2000
#5=.25

G20
G0 G17 G40 G49 G80 G90
T1 M6
G0 G90 G54 X0. Y0. S1000 M3
G43 H01 S#3 M8
G1 Z#1 F3 G04 P.05
G1 Z#2 S#4 F4
G1 Z#5 F30
G91 X1
G90
WHILE[Z EQ.25]DO1
G1 Z#1 F3 P1.5
G1 Z#2 S#4 F4
G1 Z#5 F30
G91 X1
G90
END1

G43 H.25 is the first thing that jumps out at me. The Hn should refer to the table position of a tool length offset stored in your tool offset table, eg H1 for tool 1

To use this cycle in a modal fashion would require calling it with g66 along with the relevant address codes and arguments for each variable. The program would then be recalled at each subsequent position.

Ok, I have a book so I can assign the right variables with arguments. This is very helpful. I fixed the H value. Now I see what the G66 modal means. Thanks

Not sure what your while loop is for but you need to replace z eq.25 with a valid macro statement. Ie z must be replaced with a macro/system variable.

As David stated, the Z in the WHILE block has to be a valid Macro variable, but further to this, the logic must be such that the variable can change so as to control the LOOP. Without this logic, the LOOP becomes endless without escape.

As your code includes an incremental X move, you would probably want to control the number of times the control moves the tool to a new X position and executed the drill in code. The way in which you have constructed your Macro Program is not the way I, and I'm sure David, would have done so, but to give you an idea of how to control the LOOP, I'll use your code in the example.

#6 = 1 (INITIALIZE A COUNTER OUTSIDE OF THE LOOP)
#7 = 6 (SET THE NUMBER OF ITERATION OF THE LOOP)

WHILE[#6 LE #7]DO1
G1 Z#1 F3 P1.5
G1 Z#2 S#4 F4
G1 Z#5 F30
G91 X1
#6 = #6 + 1 (INCREMENT THE COUNTER BY 1)
G90
END1

When #6 takes on the value 7 in the above example, control will exit from the LOOP.
