Winding up wire on a coil

Hello, could someone help me please. I want to program a g-code that winds up wire on a coil, by rotation of y-axis.
It should wind up forward and by obtaining the endpoint it should go backwards.

I´m thinking of a program like that. Is it possible for somebody to labour on it, to make it work.

o103 repeat [5] (repitition 5 times)
#2 = 1
#3 = 19
o102 if [#2 LT 10] (wind up forward)
G01 A360 Y[#2]
o102 elseif [#2 GT 10] (by reaching endpoint wind up backwards)
G A360 Y[#3]
o102 endif
#2 =[ #2 + 1 ]
#3 =[ #3 - 1 ]
o103 endrepeat

By the way the A is my y-axis. I hope somebody can help me.

have you seen JT'S winder example program

Ok thanks, but actually I need just the code, because I´m working with other Software and don´t know how to use this files.

All that I see wrong is that there is no "01" after the "G" in the elseif.

Thank you, I adapt the program. Unfortunately the axis doesn´t rotate after the first 360°. Do someone knows the command to set it to zero after each rotation, without rotating it backwards.



o103 repeat [5]

#2 = 1
#3 = 18

O101 while [#3 GT 0]

o102 if [#2 LT 10]
G01 A360 Y[#2]
o102 elseif [#2 GE 10]
G01 A360 Y[#3]
o102 endif

#2 =[ #2 + 1 ]
#3 =[ #3 - 1 ]

O101 endwhile

o103 endrepeat

Unfortunately the axis doesn´t rotate after the first 360°.

Try programming the move in incremental mode instead of absolute

Then you are telling it to move 360 deg not go to 360 deg, it probably won't move the second time because it is already there.

ArcEye's response sounds like the best answer.

However

Do someone knows the command to set it to zero after each rotation, without rotating it backwards.

You can take a look at G10 or G92.

The other solution is to run in feed-per rev mode and simply do repeated G1 moves.
This is what I did when winding my magneto, the code here was simply:

G95 F0.12
M3 S400
O100 repeat [200]
G1 X+25
G1 X -25
O100 endrepeat

Then the problem is, that it doesn´t stop at the endpoint of ten and is not moving backwards. Incremental distance mode g91 shall apply only to the number of degrees, but I don´t know how to put it in.

Unfortunately that code doesn´t work for my machine.
