Russ, Ger,
Russ, in answer to your inquiry about the type of axis drives that I am using. This is a very straight forward belt drive that has two motors. The x-axis is approximately 12 feet long and is a 1/4 inch open ended timing belt with 22 teeth per inch the pully is 9 mm in diameter with a 14mm shoulder and an external locking hub. The y-axis is the same except for length. It is 24 inches in length. The axis pulls the carriage for the sewing machine in accordance with the instructions in the gcode file. The problem that I was having with the scale was very simple, every time I tried to run the system on a file of a given length, i.e. 1 inch, the pattern would sew 13 inches, so basically a 13:1 increase. The cure was simple, scale it to a setting that would equal 1:1. The quilter uses basically the same technology as a milling machine, except it doesn't cut a billit or block of wood, it simply pulls the carriage with the sewing machine on it. The sewing machine is the real work horse. It has a stitch length control attached at the pedal port which keeps the length of the stitch constant no matter what the speed is. Now, here is where the problems start. Most of the patterns that I have were downloaded from a commercial site, they are made, for the most part, for long arm quilting machines, these machines have a working area of anywhere from 8 inches high and 16 inches long to over 24 inches long. My machine has a working area of approximately 6 x 9 inches, hence, pattern adjustment is necessary to keep the machine from trying to go outside the working area. Take a look at the photos that I uploaded, and you can see what I mean. There are no compound pulley systems on the machine. Each pulley does one thing, it pulls along it's own axis, kind of like a cog-wheel train on a gear track.
Ger,
You mention that all I am doing is adjusting the steps per unit. Well, I only needed to do just that, but on a permanent basis. I wanted mach3 to present me with the proper scale that would give me one inch of travel when I told it to. The macro that Russ gave me works perfectly, the settings are now present when I turn on the system and it works great.
