What tools do you have to hand?

Have a look at the links page and follow the cad/cam links, there are many free programs that will produce DXF files.

Hi Larry,

yes it can be done:-

1.  on your screen you will need a user DRO  numbered 1001

2. you write a macro with an unused number e.g. M1001.m1s with the following code in it, this needs to be saved in your current profile macro folder.

Setvar(3, getdro(1001))

3. in your g-code program call M1001 to read the value of the dro into #3

Thats all there is to it.. Send only large bags cash

You could add your fix code to the M3.m1s macro and then every time you call M3 in your program it will correct the spindle speed, I believe the problem has been sorted in Version 4.

Do you have any custom macros using # variables, if you do you may be overwriting some of the system variables and causing the override problem.

Chris,

check out the field of micro machining, this is a boom industry mainly for space and medical sectors but plenty of money for the ones that can do it.

Don't tell everybody though

That is truly amazing, from concept to part how many hours are in something like that?

This is how I would do it :-

%
O0001 (MAIN PROGRAM)

#1=0      (COUNTER MUST BE ZERO )
#2=50.0 (PITCH OF PATTERN)
#3=3      (NUMBER OF REPEATS)

G21 G40
T1 M6

G52 X0 Y0
G00 G90 X0 Y0
M98 P0002 L[#3] (ENTER L TIMES)
G00 Z25.
M30

O0002(SUB 1)
G52 X[#1*#2]
(stitch code goes below this line)

G01 X50. F100. (STITCH 50MM)

(lines below this one must NOT be removed)
G52 X0
#1=[#1+1]
M99
%

Try this, all you have to do is change the # values and place the stitch code into sub 1

Larry,

here is some code to try :-

%
O0001 (MAIN PROGRAM)

G21 G40
T1 M6
G52 X0 Y0
G00 X0 Y0
M98 P0002 (ENTER SUB)
G52 X50. (SHIFT DATUM BY 50MM)
M98 P0002 (ENTER SUB)
G52 X100. (SHIFT DATUM BY 100MM)
M98 P0002 (ENTER SUB)
M30

O0002(SUB)
G01 X50. (STITCH 50MM)
G52 X0
M99
%

This should give a line 150mm long made up of 50mm lines all joined up. Ignore what mach3 shows on the screen as it can not show datum shifts as yet.

Regards
Graham
