Arduino Stepper Driver Failure?... The Usual Suspects... 

Another great video from my favorite headless RU-vid'r.

Thanks for making and sharing this video. One thing you didn’t mention, and which I think is very important, is limiting current from the power supply. Most stepper motor coils have very low resistance and will allow a lot (too much) current to flow if the driver current limiting fails for some reason or is simply set improperly. By using the power supply’s current limiting feature, you can provide protection against “down-steam” problems like driver board failures. - Cheers - Jim

You ok Buddy. Hope you and your family has been safe

👍👍 I do something similar. I crimp a connector directly to the stepper motor leads. Those breadboards can vary greatly in their contact tolerance

Heya man, Just checking the channel to see if youre alright, love your videos, cant wait for the next one

Efectivamente, acabo de joder tres divers y precisamente por la situación del pésimo cableado que mencionas: a cada rato se salían de la PCB, no apretaban bien los jumpers prácticamente no tenía que respirar para que todo estuviera en completa calma. Ahora que sé todo esto, lo mejor es hacer lo que me propuse desde el principio y es soldar los cables adecuadamente sobre una PCB de prototipos y no en la breadboard...

@Brainy-Bits - I am wondering why BLDC motor in laser mirror of my hp 1102 printer stopped - seems like after plugin to wall there was some current and killed IC? AN44015A IC - but it still shows some V ... IT still shakes a bit when staring printer and putting near Hall sensor just a screwdriver.. weird...

Happy New Year to you too Buddy!! I hope you had a great holiday! Always love your vids, you're an excellent teacher! ❤👍

Thanks for your effort. Can you do a video on Stepper driving shields and the A4988 vs DRV8825 drivers used in those shields?

Thank you for this video very informative for an amateur like me just starting out.

Do you have a Max30100 or Max30102 oximeter you can do a tutorial for? Would really appreciate it.

Is that a 3D printed wire organizer? If so did you made it yourself or is it from thingverse?

Thank you for your information, it will help me a lot.

why did you stop posting?

Buy good quality breadboards. I avoid using those ones as much as possible. Too many loose connections. Or make a perf board version using nano with a bunch of male/female headers will do.

Happy New Year :o)

Power supply must be set to CV, not CC, and you missed lots of more steps to check what broke the driver...

Every stepper driver that I've killed was due to brain-farts. That's when you know better, but you still connect the wrong wire to the wrong place. Most common, reversing the polarity. 😖😞
