Stepper current draw

Anyone know or measured the current draw from the XY steppers or better yet the system as a whole? Trying to see how many amps I have left to play with the 36v power supply. I know the stepper torque ratings but that doesn’t really give me an accurate amperage.

If you look at the Stepper Motor Driver modules, you’ll see that the switches are set for X=3.1A, Y=4.x A IIRC.
The rest of the electronics are negligible, probably figure 500mA is a safe bet.
I’ve added a Z stepper to mine with the driver set to 1.5A and have had no problem with power supply cutout.


Thanks! That confirms my estimates as well. Still curious if anyone has put a clamp on the power wire and measured it.
