yes, i want to use It for three axis for a PCB drilling machine, yes, i want to use the PWM output from PIC to drive Hbridge can you point to examples which can accept step and direction pulse from...

Instead of measuring the filament, perhaps a load cell of some kind on the idler/extruder can give you an accurate real-time feedback of the diameter, [www.robotshop.com]

A normal PIC will drive a single H bridge pretty well. I don't know of any of them that will do three axis. Put another way - for there axis you will need three pics. The standard code I've seen does...
View ArticleRe: Real-time filament caliper sensor
Diameter (to get volume of feed) is the input you would want to have. What you *do* with that data is a bit of a challenge for the firmware.

So here it is, version 7. The changes I made are minor: - I changed for T73 relays because they are the cheapest available relays for the current needed. - I cleaned up and widened some traces to...

I guess I'm not quite sure what the 1A realy to +12 is going to do for you. It's enough current to run a fan, but you could switch a fan (or three) without the relay. I would put the 1N4001's back in...
View ArticleRe: Dual extrusion TB6560 controller
The relay is for powering up the TB6560's. The 1N4001 is for protecting the transistor driving the coil. Isn't this right? And is the diode configuration in my v4 scheme okay to protect the MOSFETS? I...

The diode on the mosfet does a couple of things, both of them good. It takes care of ESD and it acts as an inductive load clamp. It does a much better job than other approaches. The diode costs a cent...

It's possible. You'll need to modify the firmware to lengthen the step pulse on time, and invert the enable line as explained in the wiki section on Sanguish firmware. As is, the step pulse is too...

As long as you run it at half current most of the normal drivers will handle it. Whether the torque will be adequate for your application is an unknown.
View ArticleRe: Opensource PIC/ AVR bipolar stepper driver
So all you are looking for is just a simple stepper with no PWM? What sort of stepper motor? For some of them it would be about 10 lines of code.

Thank you for answer. I need only about 2kg holding torque ( of 4,4kg cm ), do you know any specific driver that my be good for these stepper?
