HOW TO Measure Current from the UltiSteppen

Recommended Posts

Hi there,

I would like to adjust the current given from the UltStepper-boards to the drivers. I know that I have to turn the potentiometer clockwise or counter-clockwise to ether increase or decrease the current.

But I don't know how to measure the new current? I have a multimeter for the measuring but I don't know where to put it.

I have read that the UltiStepper has an extra pin for this purpose but I can't find a description (or a picture) for which pin I have to use...

Thanks in advance

Here is a quote from Daid from here: https://groups.google.com/forum/#!topic/ultimaker/UklpZJhpqKs

You'll need a scope that can take samples fast enough, and you need a

current probe.

Or you need a multimeter and just measure the voltage on the "wiper

pin" of the adjuster pot. Which is what is connected to the test pin.

The wiper pin is the single pin on the side of the pot, the other side

has 2 pins. This needs to be about 0.6V


Does he mean the "pin" directly touching the "adjuster pod" (potentiometer) facing us on this picture? =)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
