Re: repstrap electronics
Quotewhat makes the steps time sensitive? They give the stepper motors speed. Above some base speed, you can't change speed deliberately, not even on stepper motors. You have to accelerate and...

Stepping AND Direction pins need to be closely timed. If the Arduino spits out a direction high and stepping signals, and there's a delay of the direction pin, there will be a few counts by the...

i measured the pot to ground and set it to 0.300amps and powered this motor no smoke and was pleased with my 1st attempt but once they go on printer and have a fan on the drivers, maybe try 1amp but...

I have a lot of time... so I'm going to give the shift registers a try. At least I'll find out if it works or not. I'm leaning on the side that it will have to be slowed down so much so it doesn't...

L293D is a very primitive driver, and is 600mA max. it doesn't actively limit/control the current and its functionality is very straight forward. For these kinds of IC, you must use a motor that its...
