Array offset

Hello,

Hello,

I have a milling operation that needs to be repeated for example 4 times.
Assume I have the GCode for the first.

How can I programm an array to repeat the operation with a specific deta in X and Y, say for example delta X 2cm, delta Y 3cm ?

That would lead to 4 times the same operation but with a homing offset of

X 0 Y 0 for the first
X 0 Y 3 for the second
X 2 Y 0 for the third
X 2 Y 3 for the 4th

I set up some files to do just that this morning. This might not be the best way but it works for me.

To do more than 2x2 change the numbers in the brackets to the number of desired repeats in that direction.
This code will make all the repeats in an X row then start over with all the Xs in the next Y row....

Thank you !
I see the process here.

Wouldn't it be even better with a final G92.1 to do a final offset reset ?

Yes, it would. I have one in the normal post-amble of my files, and it didn't get included in the copy and paste.

Hello,

Found out that the G-Code was not correct when having more than 2 lines in the Y direction.
Below is a corrected G-Code

Thanks,

I have never tried to run more than 2 rows in the Y, so I missed the error.

Thank you for the code!


It works for me but it makes an extra, unnecessary move on X after each line and one move on Y after the last line.
Is it the program that does that or my frankencode(I don't understand everything in it yet, is more of a work in progress understanding G code)?

This is an exemple:

G92.1

G21 G17 G90 G54 G64 P0.001
(5.5mm JOBBER DRILL)
T09 M06
S4500 M03
M08
G90 G54 G00 X0 Y0

O100 sub

T11 G43 Z25. H09
G83 G98 R3. Z-10. Q2. F354.33
G80 G00 Z25.

O100 endsub

#1=4 (number of items on Y)
#2=4 (number of items on X)
#3=72 (spacing for X)
#4=72 (spacing for Y)

O102 repeat [#1] (number of rows Y repeats)
O103 repeat [#2] (number of columns X repeats)
O100 call
G0 X#3 Y0 (width of columns)
G92 X0Y0
O103 end repeat
G0 X[#3*-#2]
G92X0
G0 X0 Y#4 (length of rows)
G92 X0Y0
O102 endrepeat

G92.1

M2

This modification doesn't make unnecessary moves. Also no G92, Sub,and repeat. The problem in your routine is, the xy movement after o100, G83.
Because sometimes brackets get lost in the uploaded files, there is a screenshot, how it should look.


EDIT:
Toolpath changed to: ZigZag orthagonal along X
