[shiva]

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?
If it is problem of current(I am using A4988) how to adjust and what current output should go to each stepper?
Thanks
Shiva

Hi,Shiva
Sounds impossible...Such a high temperature(70c)!
You'd better check the voltage on driver A4988:

Hi
I have check voltage as shown in your link.It shows 5.3volt and 11.9 volt.I think some other problem.
