How to wire this PID controller and PWM controller
Hi All, I'm a mechanics and very weak at the electronics side, I want to build a roller that turns in very consistant low speed with high torque for over 24 hours. I have got a PWM controller with...

I have very basic experience in measuring electronics, also isnt the dir pin connected to ground? so where else do I connect the tester to (http://www.pololu.com/product/1201) at the bottom of the...

im guessing I shouldve connected the tester to the dir pin and the volt meter, and it was 4.1v always if I clicked + but when I clicked home or - it went to negitive .5v and stayed there untill I...

... this sounds good in relation to 'working DIR-pin' -- -0.5V and +4.1V are the two different values indicating the different moving directions ... and the levels seems to be OK for me. The issue...

today I changed the connections (motor to the ab pins) from quick connection to solder, and it seemed to stop the random changing direction, and for the only one direction turning, I dont have any end...

if its overheating, I bet its either the fuses or the mosfets or the stepper controllers. 12.48v is perfectly within spec. I belive the arduino voltage regulator gets sketchy after 15v or so, so your...

I cant find how to invert the endstops, so instead I have some switches (endstops) and I connected them to the arduino and pressed them, now the motors go reverse!!! thank you!!! but it be really...

... this settings depends on your firmware-sources, but most of them should have a file "configuration.h" in the source files, where you can change all parameters and pin-wiring or behaviour. After...
View ArticleRe: Stepper motor randomly changing directions?
As the Dir signal changes as expected, it can't be a endstop/firmware problem. Also, if M119 reports what's expected, endstops actually do work fine. Did you solder the pins into the Pololu? I had...

The Mega needs replacing. You've fried the analog input for the hot end on the Mega board.

As the Mega has many ports it should be possible to route this signal to another pin. If you're fine with handling a soldering iron and editing your firmwares' config.h, that is.
