Thanks for this one, saves a lot of my time and resolves few problems that occured at my project! First complete guide, and i went through at least 10-15. Thanks!
I just set it to 80% of the current that the motor can handle. As long as it is lower than whatever the driver can deliver, what would be the problem ?
This does not sound right. Make sure that you are doing everything correctly and that your connections are solid. Try another board. Maybe the one you're trying to adjust is defective.
Can I use this "driver" for a PM25L -024 stepper motor ? The motor specs says a current rating of 600 mA, The data sheet for DRV8825 says 8-25V, www.ti.com/lit/ds/symlink/drv8825.pdf
VMOT = 12V VDD = 5V ENABLE = GND connect RESET to SLEEP MS1, MS2 and MS3 to 5V send pulses to STEP set DIR to GND or 5V Google images for Sanguinololu schematic for an example of how it is connected on a 3d printer controller if the above is not clear
what voltage and amps do you use on a variable power supply when callibrating the driver? i tried setting up a drv8825 with a nema17 with arduino and when i turned on the power supply, the capacitator exploded. i might have put accidentally switched the - and + pole and now im kind of afraid to turn it on. it also might have been too high of a voltage and amps on the variable power supply
Perfect tips ! Those small metallic screwdrivers are so handy to have lying around the bench. Thanks for another informative video Artur!
Very straightforward. Good explanation about voltage vs current.

Very well done Sir! Thank you for the tips!
doyle maleche thank you! I'm glad you liked my video
Thank you Arthur. As usual very knowledgeable and useful.
Thank you!
Great video! Thank you for sharing
Respect! Great details learned, thank you
Thank you!
So where should I put my ground wire?
I just set it to 80% of the current that the motor can handle.
As long as it is lower than whatever the driver can deliver,
what would be the problem ?
In my case it is around V*1.5=A somehow. Feeding 17HS19-2004S1. You should check actual amperage - maybe your current is way below than what you say.
How do we meassurre the actual current that drive the motor beside the meassurrement of vref on pot
good video
I can't set drv8825 vref to 1.3v .. It is very sensitive and changes constantly : 1.3v to 3.5v to 5v!... are motors safe?

great work
can i get the test circuit please.
VMOT = 12V
VDD = 5V
ENABLE = GND
connect RESET to SLEEP
MS1, MS2 and MS3 to 5V
send pulses to STEP
set DIR to GND or 5V

sorry for the question as the controller does this
Can the drv-8825 handle 20V and above?
Yes
Just check the data sheet
if my power supply is 5v how do i change it to 2.5 1.8 a as a novice i need to understand this
Not sure how your question relates to this video but generally you'd use some sort of voltage regulator.
