Pretty sure you need to plug in the steppers before installing the drivers and power. Can cause the boards to fry. This was clear in the instructions I received and in some other videos...

[ivangutowski]

I literally just watched a video that said, whatever you do, do not power on the board with no steppers attached - zero out the pot and then build it up slowly.
Potentially could blow all your drivers

[juliocesarleguizamon]

the formula to regulate the voltage of the dvr 8825 according to the manufacturer's sheet would be "i max = vref ÷ (5. Rs)", because you calculated it with those values

[pepperoni]

The sample code was just what I was looking for. I wanted to create a custom sketch to control the motors. Thank you!

[tomnorman]

I thought powering up the DRV8825 without a motor attached would cause it to fry...what up?

[ivangutowski]

To set the stepper motor power the usb arduino and power supply need to be on, also all the drivers share the same ground pin so a male to male wire connected to the multimeer saves having to twist and balance whilst trying to take a reading

[RandomProjectswithSam]

In other videos they mention you shouldn't install and power drivers unless the steppers are attached without risking burning out the drivers yet here it looks like its done. did you blow out any drivers doing this?

Thanks for the tutorial! I'm using this without GRBL and trying to find out how to add limit switches and push button to start a certain movement. Can you help or do another tutorial about this? Thanks!

I Must say Thank You Many times and Hat Off - I watched so many tutorials with NO luck Uploading ... Yours was OK from the first tray ... Please Keep up the good work and Keep Us on Loop with whatever You do ... Thank You

Parabéns pelo vídeo. Muito didático e sem enrolação.

I'm a total beginner and don't know anything. Mahalo for the great video. One quick question. Where do the + ans - wires lead to? Do they go to an adapter that plugs into the wall or do they remain unconnected b/c there is a port to plug the little adapter into, and there is a terminal for the other wires.

Hi. If I want to pick a power supply for the shield using all 4 axis. What's the lowest current limit property for the power supply? (0.75Ax4 or 0.75Ax2x4). Is 24V 6A a good option?

[sunilchaudhary]

Mam how much total voltage must be input in shield for 3 or 4 motor running in one shield?

I try to run 3 motors with 12volt and one motor not run properly. That motor is fine because I change with other and there it run properly.

[donovannewton]

I’m a little confused as to the 1.5A. The stepper shows a 1.7A max, so why 1.5A?, is it just to give it a bit of breathing room. Does voltage affect the VREF as well? Is there any difference between 12, 24 or 36v power usage?

[boks]

I tried a few sketches but yours was the one that worked, don't know why, but nice work.

[Eginger]

Hi! Wonderful video. I have a couple questions. In your computation of current limit for DRV 8825, where did "x 2" come from? I learned in school you need to divide voltage by resistance to get current. VREF is voltage, isn`t it? Thank you for your time.

Awesome video
Keep uploading this type of useful videos
All the best for future

Wont motor drivers be fried if you power the motor drivers without attaching the motors ?

[glenaw]

Have you made or will you make a step by step on how the sketch is fed through the software? would like to see the steps . Thanks

[julianjuellz]

thank you for your informations :) can you maybe help me on how to control the stepper motor speed with a potentiometer knob? how would i implement that?
