Heatsink Detached on Mother Board

Recommended Posts

I got a second UM original and when I opened the Electronics Box I discovered that a heatsink on the mother board was detached. I mounted anyway and when I finished to build the 3D printer, I switched on and is working.

My question is the absence of the heatsink is going to cause problem?I plan to use the 3D printer for long prints.

Is there a way to stick this heatsink together or is better to ask for a replacement directly?

Yes this will cause a problem with the extruder. The stepper driver will overheat, and cause skipping, or may damage it irreparably and will have to replace. Fear not however, the exact same think happened to me. I went out and bought some silver thermal glue: http://www.amazon.co.uk/gp/product/B002HT1X9O?psc=1&redirect=true&ref_=oh_aui_detailpage_o07_s00

It's worked perfectly, and have plenty more just in-case it happens again.

Same story here, when I opened my UMO to retrofit a controller, and most of the heatsinks fell off the board.

I am using the same drivers without heatsink for another Arduino project, so I was not too concerned, but I eventually glued them back with the Arctic Silver Thermal Glue.

Be careful, this is not the same as the 'standard' thermal paste, as it is real glue, so never use it for a processor fan!

    • "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.
