mach3 quilting machine again.
« on: April 06, 2021, 02:13:41 PM »
Hello members....i'm not sure if this post is in the right area but here goes.
I've converted my wife's 10 foot longarm quilter to Mach control....well, almost. X and Y axes work great while using arrow keys on the  keyboard. But I have an issue with control, as follows.
I have an edge to edge pattern that I converted to G-code with Lazycam. These patterns have a starting point and ending point and are intended to be repeatable across the width of the quilt. The profiles that are with the Mach3 download won't work because they don't follow the continuous line that's in the design. They jump all over the place. You can see this on the "Z" DRO. Tried plasma and turn profiles without much luck.
I guess this involves a specific profile for quilting........designed to follow the continuous line from start point to end. My question is, I guess, what is involved in creating a new profile to handle that job.
Between a rock and a hard place right now....any help would be greatly appreciated.

Mach3 will ONLY go where the Gcode tells it to go under machine control. Post a sample of the Gcode.

(;-) TP

Can you attach the pattern in vector format?

OK, I took a look at your vectors, and in your file there are 162 individual ones :)
The one attached is a single vector and should be done without  lifting Z until it reaches the end.
Also, try the attached G-code (edit it to  suite your needs).

Thank you very much.
As you can probably tell, I am totally new to this CNC aspect. Trying to learn as I stumble along. The program I sent you is awesome now. I just have to resize it , depending on quilt size, and also start on left side of pattern instead of right. What program did you use to modify it, would Lazycam do that? I guess it working with layers?? I have some studying to do obviously. Thanks again, greatly appreciated.

I'm using Vectric Aspire.
G-code that I sent starts on the left side :)
There are a couple problematic points in the drawing that I had to address. Some circles were just that - circles, had to be cut as well as other places where cutouts had to be made.
After, all was easy. Select all vectors and Join them.

Multiplying is also easy :) Just Join ends of copies together.

That's amazing. Greatly appreciated. Not sure if I have enough time left to learn it all.  Thank you very much.

Your vectors could be joined in Corel Draw, but it takes much more time, and when you export such continuous vector it is made of zillion of straight segments (as can be seen after importing in Aspire).
