Steppers voltage

Post by Matteo123 » 01 Feb 2017, 09:22

Hello,

Can someone tell the correct voltage of every stepper motor?

My extruder 0 stepper seems becoming very hot and X stepper too so i would like to test and fix every voltage

Thanks

Matteo

I followed method explained here:
https://beeverycreative.com/forum/viewt ... tage#p1822
now the extruder stepper doesn't heat anymore :D :D :D

The value i set is about 0.65 volt for extruder stepper

However if someone knows correct voltage please tell so i can check every stepper in little time. Bye Bye

IN THE THREAD YOU CREATED A LINK FOLLOW THE ADVICE THERE TO CHECK.
MOST STEPPERS RUN AROUND 1.2 TO 1.6 VOLTS NO HARD FAST RULE WHATEVER WORKS FOR YOUR SET-UP.
BEST TO START WITH A KNOWN GOOD STEPPER BOARD.

FEEDBACK ON STATUS!!

I trimmed the steppers down to about 1,4 Volts.
They don't heat up anymore if just locked. But in full action they still get rather hot.
Is that normal or should I step down the voltage a litlle bit more.

BTW, I measure the voltage between earth and the small potmeter on the drivers. Is that the correct place to measure?

I lowered my voltages to the following values, 0.8,0.8, 0.8, 0.8, 0.8 (X, Y, Z, E0, E1 from the top to the bottom of the board) and it's working very well :)
Yes to measure the voltage you put the positive tip of the multimeter (red) on the center of the potentiometer and the negative tip (black) on the negative input on the board (where you connect the 2 cables from the power supply).
There's a video showing the process on Youtube i'm trying to find it

edit: Found it

Sorry, i'm 100% noob..
How do I change the voltage of my stepper motors? Is a software thing, or do I have to open up the motor case and do electric things to it?

Hi João look at the video I put on my last post and the post I made a while ago with a method that doesn't require measuring the voltage, by eyeballing the correct position of the potentiometer here :
viewtopic.php?f=8&t=693&p=2696&hilit=voltage#p2696

If you do the method of measuring you have to use a multimeter and put in on DC voltage mode and put the black tip on the negative side coming into the motherboard and then use the other probe, the red one, to measure the voltage at each stepper driver by pressing on the small potentiometer on each of them, being careful to not touch any other contacts while doing so, I highly recommend removing the fans first.
Then after measuring adjust all of them to about 0.9-0.8v and then the motors should heat um much less, make less noise, and the extrusion will be more consistent with less jamming.

Excellent!
Already got the fans out and the multimeter in..:)

Nice, after adjusting to 0.9v you should already notice quite a difference :)

Done!
All steppers between 0,80 and 0,85 Volts..quite easy and simple, thought that will be painfull hard, but turns out a 5 min task..
Thanks for the objective and simple instructions! :)
