Things are good!!!
Well, I was a little surprised to get the speed I got. Right now I am right at 80IPM! The motors don't have the torque to start out at that speed, so I will have to experiment with the speed and find out how quickly it will change direction, etc.
It was cold in the garage tonight, so I will have to go out there tomorrow after I get some more kerosene and get some video for those interested.
I find that sometimes you have to improvise a little. At work, I removed a line supply from a piece of equipment because it was more than a little charred. This is basically an unregulated linear power supply. (We use a separate switcher supply that does all of regulation.) It had been in one of my drawers for about 3 years. In fact, I had almost forgotten about it. Anyway, despite the appearance, it still works. (Well, most of it anyway. It has a crowbar circuit to blow the fuse if anything downstream fails. More often than not, however, the crowbar circuit sacrifices itself to save the fuse, and when it does, it takes a good portion of the board with it.) I had scrapped the part, but saved it, because you just never know when you might need a burned, charred, scrapped power supply, right? It puts out about 25 VDC when unloaed. Loaded, it puts out between 18 VDC and 22 VDC, depending on the load. The power supply that I have been doing all of my stepper testing with was a 13.5 VDC supply. With one supply isolated from ground, and the two put in series, I have enough voltage to move the motor at a pretty good clip.
So I started the motor moving and sped it up to the max speed of my controller and let it go for 15 seconds. It moved a little over 19 inches, but that included the time to ramp up. I may alter my test circuit a little to see just how fast it will go, but then again, I may not. I doubt that I have enough torque at that speed to be useful, so it would really be just to know.
So tonight was good. Now I'm tired, so I'm going to take a shower and call it a day.
