Temp sensor LED lights when moving the head!

Recommended Posts

The stepper motors act as little generators when you spin them, so yes, it's normal.


Ok although I don't get why the electricity that is produced from the motor goes through the temperature sensor's circuit.

Beside sharing a common - I don't understand how is a closed circuit motor and temperature sensor.


But only in one direction for each axis... ;)


I does it on both directions, both axes!

That's interesting. On my UM1 I only get the effect in one direction. And it made sense to me as LED are diodes. :blink:

I try to avoid moving the print head fast (which results in higher induced current) as the electronics might not like this kind of induced power. :sad:

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
