Microstep Driver connectivity ?
JohanEkdahl, I got them from these guys: http://www.motioncontrolproducts... @ £21.50 + tax I've seen them with other labels on other UK sites at a similar price. Not looked...

Microstep Driver connectivity ?
In the deep end! I've tried just toggling a port ... and it seems to work. At least no pyrotechnics yet! Is it really all I need to do? Surely I risk damaging the chip,...

Microstep Driver connectivity ?
The sad thing is I have the bench, and a serviceable shed/workshop, I just can't get in it for the 10 years worth of accumulated clutter my wife's keeping for "when our son leaves...

ADC stepper motor control
Well thanks to Carl I can report some progress. It now turns one way at low voltage and the other way at high at a fixed speed. * Program is supposed to read voltage on C0 and...

Quote:If not, use really long delays and LEDs to visually look at the output pattern. Taking out the equations from main and just putting time=100 makes no difference to the...

ADC stepper motor control
Hi Carl, I've given it a try, but with the time calculations in main() I'm getting no time modulation. Just nothing or a high pitched hum depending on the pot setting. Where do...

Thanks Carl, Points noted, I'll try better in future. That's really helpful, it simplifies some code examples I've been struggling to understand. I'll crank up the aging grey...

Sorry, I don't understand the relevance of the 2ms step time. Could you explain?

ADC stepper motor control
I'm planning to do x,y,z, not rotation. It's for a macro application at about 1x. The z is a bit of a luxury, but I'm thinking of a gearing for fine focus, which will need to end...
