Setting the Steppers current for MeCreator2 ? (A4988)
Posted: Thu Jul 11, 2019 5:19 am
Hi, My printer MeCreator2 is equipped with a variety of motors and each of them has different nominal current:
The motors are as follows:
X - 42SHD 0217-24F ... Current = 1.5A
Y - 42SHD 0034-20B ... Current = 1.0A
Z - 42HS3418-305N8 ... ???
E - N42HS3418-24B22... ???
For the Z and E motors I could not find any specs, so I don't know their nominal current.
Also, the Drivers seem to be A4988, how do I calculate the current based on Vref on this drivers? I cannot see the resistor value because of the heatsink on top.
Please advise with the following:
- Nominal Current for Z and E motors
- Current calculation formula for A4988
Thank you.
