For example, a 7i40 is rated at 10A. You would set the PWM rate to suit the current requirement, then toggle the DIR and ENA pins in a sequence to generate the steps. However, the Mesa Hostmot2 stepgen isn't really flexible enough for this, so you might end up with a weird hybrid system of software stepgen and hardware PWM etc. Also, the 7i29 is $300 anyway (the 7i40 is $150) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
