Stepper motor getting toomuh heat

Post by Melita01 » Sat May 29, 2021 7:34 pm

Hi
I replaced Stepper drive for my I3ProX.My all stepper motors getting too much heat about 70c if I run continue 45 minutes .I cant touch that.What is problem how to correct it https://trackeasy.fun/usps/ https://showbox.tools/?
If it is problem of current(I am using A4988) how to adjust and what current output should go to each stepper?
Thanks
Melita01.

Seems you neeed to adjust the voltage (vref) of your stepperdriver in order to your motorcurrents. There are a lot of videos on youtube which show how to do it.
