General Mach Discussion / Re: How can I configure Mach3 for motor enable with step??
« on: May 11, 2011, 10:56:30 AM »
Tom's excellent work should not be dismissed but control has moved on leaps and bounds with the introduction of cheap stepper motor controller chips from, for example, Toshiba et al.
These chips can incorporate microstepping, automatic current reduction when idle and provision to combat mid band resonance amongst many other refinements over the basic, home constructed driver using discrete components.
It may even be cheaper to purchase the TB6560 and associated components, copy Toshiba's recommended circuit and build your own controller that way. Alternately the multi axis imported boards from China which use the TB6560's may be an even better solution.
If you have ever seen the difference between a stepper controller operating in full or half step mode compared with a stepper motor operating in 1/8th step mode you will know exactly what I mean.
