Hey Graham,

This one works so good, I think now I am going to write a short macro to call it up and allow me to make the entries from the screen and not inside the file.  Also, I found a way to display the number of reps left to complete on screen.  That works amazingly well.

Thanks for all you have done, you are truly a god among men.

Graham,

Yep, this one works even better!  Now I need find a way to display the number of reps on screen.

Graham,

I tried the new code that you provided, and it worked like a charm, now to write a macro that will ask for the datum shift and set up a loop to count the number of repeats.  Graham, you are truly a wizard among men.  Thank you so much!

Graham,

Basically, I have a cnc controlled quilting machine that I built.  It is simply an X-Y axis machine.  It runs in only four linear directions.  The x-axis is the longitude of the table which is approximately 12 feet long.  The Y-axis is the carriage for the sewing machine and it is perpendicular to the X-axis.  The patterns that I use are simple vector patterns that are mostly continuous line drawings.  What I am trying to do is start a pattern, and at the end of the pattern, have the dro reset to zero without moving the carriage back to the datum, then restart the sewing of the pattern so that the entire operation appears to be one continuous pattern sewn multiple times in a row, X number of times from edge to edge on the quilt.  This is called continuous line pattern quilting.  The problem that I am running into is that when I use the G52 and/or M98 in my files, they only repeat the pattern in the same place for the number of times designated.  Of course, this won't work because all of the stitches pile up in the same place one on top of the other.  I hope this gives you a better idea of the issue that I face.  Put another way, imagine a wave line on an oscilloscope, that is what I want the pattern to look like, connected end to end.

Graham,

I tried the code that you recommended and unfortunately no joy.  The code would work if it were a milling machine, however, since it isn't, the quilter only recycles to the front of the pattern and starts over at the datum.  I have been fighting this issue for about 6 months now, and I know that there is a way to do it, I just can't find it.

Graham,

I'll give that a try and see what happens.  I'll let you know what happens.

Graham,

I've built a cnc quilting machine, that uses Mach3 to control it.  I need a way to reset the dro's to zero at the end of a pattern, and then restart at the same place, thereby extending/repeating the pattern, connected end to end.  Any ideas?

Hi Scott,

A quick one-off question for you.  Is it possible to make a macro that will zero an axis dro from within a gcode program, without moving the axis?

Hey Tweakie,


I got a question for you.  I was playing around with the GCode files that I use for patterns, for my CNC Quilter, and I set up a file to repeat the pattern using G98 and L for the number of repeats.  I noticed after the first pattern ran, and the program hit the M99 at the bottom of the file, the whole pattern slowed down tremendously, like maybe 400 percent of the original speed.  Any idea what may cause this?
