Subject: G code subroutine repeat

Is there a graceful way in Kcnc G code to repeat a profile multiple times in a series of rows and columns with a specified x and y offset for each repeat?  

For example  I want to repeat a profile that is 3 inch x 4 inch in a piece of material that is 20  x 30 inches.  I would like to specify 6 columns and 7 rows without just generating the raw code for each location on the part.  The program would continue the repeats without intervention until all are complete .

Hi AZ,

I'm not sure how graceful but you can use GCode Variables and Subroutine Loops.  See attached Gcode and Plot.

Thank you, That sure beats the buckets of G code.

Hello,
I am using the array sample and noticed that halting the motion in KmotionCNC (either F5 or button) somehow confuses the G54 offset.
 For instance the example below. If I halt it inbetween and restart, KmotionCNC tells me that softlimits are violated and motion cant continue. What could be the reason for that?
I also noticed, that with such a subroutine sample the deceleration when hitting F5 (halt) is very slow; which is not the case if I use a non-subroutine gcode. In the latter case deceleration to stop is quite instant.
Kind regards,

Johannes

Or might the problem be the G54 definition that I additionally introduced after completing the entire pattern?:

G10L2P1X[#5]Y[#6]
G00 X0Y0

?
I can only access the machine again tomorrow..
Kind regards,

Hi Johannes,

Sorry for the delay.  I think the issue has to do with re-winding the lookahead for the Interpreter to restore previous GCode Variable States on a Halt.

Here is a patch for Test Version 4.33l that should resolve the issue.


Please let us know if it resolves the problem.

Thanks
TK

Hi Tom,

no problem for the delay. The pattern milling saved so much work already;) Being able to stop inbetween will make it even more powerfull.

Is it correct to copy the dll to this folder? :
"KMotion433l\KMotion\Release"

There is a larger file with the same name in folder
"KMotion433l\KMotion\Debug"
but maybe its not used in regular processing.

I upgraded version 4.33l to 4.33n, I guess this will not be a problem in combination with this patch?

Kind regards,

Johannes

Hi Johannes,

Yes, copy the GCodeInterpreter.dll to the KMotion433l\KMotion\Release.

The Debug directory is not used unless you are running debug code which you normally would not be.

Yes, please also use the patched KFLOP Firmware (DSPKFLOP.out) V4.33n

Hi Tom,
great! Will give it a try (in the comming weeks only..) and let you know.
Kind regards,
