Um2+ main board aging: adding a fan to cool the board ?
I have been using this output (24 VDC) since 2016 for two 12 VDC fans, connected in serial for cooling the main PCB that have been working perfectly all the time and still do.
Number one problem for the electronics is the "overheat" that is killing the semiconductors, number two problem -is the humidity!
Those two fans have cooled the whole upper part of the main board. There is no brownish colored stepper driver circuits and the board look as new after seven year..
So, go and use it, this is your best ensourement! Just use it!
This is a direct 24 VDC when power switch is turned on.
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
