Questions tagged [power-supply]

A part of a device which converts the current of the power network to the properties required by the device.

Its main types are:

  • Linear power supply
  • Switching-mode power supply

It can be stabilized or not. A stabilized power supply has electronics to provide such an outgoing current, whose characteristics are independent from the changes in the external power, or from some changes in the power supply itself.

How to change the voltage on a FLSUN QQ

I just bought a FLSUN QQ and the instructions say I need to change the voltage from 220 to 110. Sadly the instructions don't say how to do that. Can anyone tell me how to do it?

Power OctoPi from printer

I'm wondering if there is some trick to power my OctoPi with the power supply of my 3D printer. I'm using an Geeetech I3 Pro W. The power supply itself should be able, but the output is as far as I'm aware of 3.3 volts. Not my desired 5 V for USB,…

Will this MOSFET allow the heat bed to run at a different voltage than the control board

I am currently running my Tronxy X5s with a MKS Gen L board. So far I have not ran the heat bed over 50 degrees C since I have only printed with PLA so far. I plan to try PETG and/or ABS in the near future and I have a spare power supply 12V/360W…

Ender 3 Won’t Start - flashing screen and blue LED on main board

Just received my second Ender 3 (see my other questions for the problems that first one developed). Figured it best to have a spare while I upgrade my first one with an ABL. I assembled it as normal, without any issues, but on applying power the…

Effects of bad power supply on temperature/flow?

I've been trying to trace down a mysterious reduction in the flow I can achieve. Since recording this flow test video where I successfully achieved a nominal 30 mm³/s (almost surely with underextrusion, but with no skipping or warping), something…
