Cooling off in Layed back mode

Recommended Posts

Hey

I want to play around with the steppermotor-current again. In the UM-Wiki it is said that one should not tune the potentiometer while running in Laid-back mode without cooling.

Does that mean I...:

- ...should not print anything while tuning the potentiometer (which would be crazy)

- ...should not turn on the printer while the fan is not attached (that would make it impossible to directly measure the reference-voltage on the steppers. i would have to take them out and measure one after the other)

- ...can turn on the electronics but make sure that neither the fan nor anything else is moving (as this may lead to some part of the electronics heating up and failing due to lack of cooling)

Link to the above mentioned page:

It simply means you need to keep the stepper controllers cool. So if you remove the cover you need a powerful fan and you need to keep checking the temperatures often so they don't melt.

Maybe a desk fan.

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
