    Re: And the GOOD news is.....

    By all means congratulations! Just be careful that some in Washington don't discover you. I have a feeling that you'll rapidly become a part of the class 'Not paying their fair share' in taxes....

    Re: Stepper motor question

    Hey Andrew,
    I am by no means an expert but I was able to get my NEMA 17 unipolar stepper motor running about 600 steps per second using SPIN and one COG. I'm pretty sure you could do any speed you...

    Re: Timing issue

    Thanks Jon,
    The entire program is posted in the completed projects forum. It's the original iteration of the program so I'm sure the problem would be obvious to the experts. To fix the problem, I...

    Re: Timing issue

    I got it fixed but I didn't figure it out. I segregated all the timing loops in its' own cog and it worked perfectly. When the timing loop was in the main body, it would always take 2 seconds on the...

    Re: Timing issue

    Odd. Still didn't work. I used the serial terminal and displayed 'minutes' before and after the case statement. Before, it showed 3 and after it showed 2 as expected, but the second time through the...

    Re: Timing issue

    Thanks Jon. I shall try that. I thought it must have been some sort of timing issue and I am not schooled enough in spin to have figured it out yet. Best regards.

  21. Little Step-U vs BiStep motor controller.

    I'm sure you read about the 22k resistor unless you're using the SIN pin. I'm not sure if that would have an effect on the input only. also try 8 bit no parity inverted (16780) for 2400 baud. I...

    I think I may have found the problem. I need to use the ramp-up feature for higher speeds. I just can't start it at say, 3000 steps per second as the motor won't respond. If I ramp up to it, I think...
