Script bash

Hi

Now that I know what you want, may have an idea.

This python program will automatically transform a gcode program, by flipping, mirroring or inverting axes.
sourceforge.net/projects/gcodetransposer/?source=typ_redirect

So having a button which activates a halui MDI command, which in turn runs a user M code script could

Take the current gcode file and run through GCode.py to flip X and Y moves, outputting filename-reversed.ngc

Use axis-remote to load filename-reversed.ngc

It can't be completely automated, because you still need to touch off to a new origin, or the 2 parts will touch along the 'mirror line', but it should give something to work with.

regards

PS
How do you get the current loaded filename if they vary? Sounds simple but isn't.
See my Axis modifications at mgware.co.uk

Hallo.
Sory for the delay I haven't an internet in my workschop.


''It can't be completely automated, because you still need to touch off to a new origin''

I was thinking that Filter replace simple G54 -> G59.
MY idea is to Flter evryone g-code but produce mirror if (CONDITION) signal from button right is true.
When false put orginal g-code.
Next AXIS_REMOTE.
Ofcourse i dont' know how to check the signal/pin inside FILTER -script.
Sometimes ago I was checking GRECODE but it need terminal.
I belive that it can be automated becouse oly then it's soluion for me .
I appreciate your time.
Regards

If you know where your new origin will be in relation to the old one , it could be automated.

You could go to that point in your current co-ordinates and then use G10 L20 to set that as the origin in a new co-ordinate system and switch to that.

The FILTER script is a bit of a blind alley which is masking other alternatives
They are meant simply for filtering a file loaded into Linuxcnc and producing an output that can be run as a ngc file, a graphics file though image2gcode for example.

Your idea already requires operator intervention, to press a button which indicates if the program should be normal or mirrored.

Why not use this button press to initiate what is required, rather than passively wait until a file load and then try to find a way to test if mirroring is required and do it inside a filter?

Old program finishes
Button press
Current file is processed to produce a mirror version
Axes are moved and shifted to new origin in another co-ordinate system
Mirrored file is loaded
Off you go again

There are a lot of other ways to do it too, I don't know your whole work process.

Thanks again you are raely quick .
Now I see that can be good way.

I'm readig script and trying to understand "sourceforge.net/projects/gcodetransposer/?source=typ_redirect"
But I 'm not sure which part schould put inside my ( script.-M150)
Supose in INI I have :

MDI_COMMAND O<RM> CALL
### I' not sure abut it above maybe MDI_COMMAND M150
Ofcourse MDI_COMMAND conected to button
Inside subroutine I schould put custom cod supose M150
M150 should include part acountable for mirror and replacing my Ocode responsible for horizontal drillings
Example if O<horiz_drill_x+>
then replace to O<horiz_drill_-x>
Can you help me write it corectly.
Regards

I'll have to leave Andy to explain his thoughts conclusively, but the way I read it is this.

Start with file part-normal.ngc, that goes in LN

Run through the gcode transposer to produce a vertical mirror image, that goes in LM

Run through the gcode transposer to produce a horizontal mirror image, that goes in RN

Run that code through gcode transposer to produce a vertical mirror image, that goes in RM

Then you have code which will produce each possible 2D mirror transposition of the original, just wrap them each in a sub and you can call them from
mdi commands attached to buttons

regards

.....long day
I know that you give me all tips thanks.
But I'm not a programer and don't know how?
I can make button and connect to MDI_COMMAND O<LN> CALL,
I wonder what is necessary to put within O<LM>SUB

If I understand corectly I schould write sub

O<LM>SUB
G55
M150 (inside schould put GCode.py -all content , or only part responsible for mirror)


O<MIRROR_PART> CALL
O<LM> ENDSUB

I feel that I do not understand something.
I have to ask for support step by step .
I am grateful for help.

Hopefully tomorrow I will have time to put what I believe Andy was outlining, into a sim config, so that you can see it working.

You still seem to be leaning towards dynamic gcode transformation.

Do you use that many different programs on the one machine, that it is not practical to have a stock of 4 for each part, to cover all rotation possibilities?

If so, the answer would probably be to script the production of these rotations through a filter program.
That program can then write the code into a sub saved under a preset name which will be hard coded in the MDI command associated with a button.

It would be akin to the solution you first thought of in part, except that the filter produces all 4 possibles and the operator chooses which one to use manually via a button.

Still do not know how you deal with the issue of changing the origin for the next part to be cut.
Do you manually move to a new origin and touch off? Or have some automated offset from the existing one to achieve this?

regards

Hallo my machine looks almost like.




""Do you use that many different programs on the one machine, that it is not practical to have a stock of 4 for each part, to cover all rotation possibilities?""
Yes I have only one cnc machine and unfortunately all day, I have to write new program .
Evryone program is different becouse evry cabinet kitchen are differ ofcourse there are similarities.
Just therefore I love NGCGUI.

""It would be akin to the solution you first thought of in part, except that the filter produces all 4 possibles and the operator chooses which one to use manually via a button.""
Thats great.

In video youtube you can see that on the table are permanent base/support when I ferstly press button base rise then I put material when put again button base fall and program run.
LEFT BASE G54 X0 Y0 Z0 (here normal part) LEFT BUTTON
RIGHT BASE G59 X3500 Y0 Z0 (mirror part). RIGHT BUTTON
Many thanks.
Regards.
