Ultimaker 3 Extended control board

Recommended Posts

Does anyone know the make and model # of the control board used in the Ultimaker 3 extended?


We just got ours and it printed 1 thing,  then the limit switch would not detect the print head on the X axis.  Now the printer will not power on.  I am in contact with the dealer,  but I would like to have some info going into this problem.

There are several different boards in the printer; the main board (powers the motors and heaters), the Olimex board (wifi and camera modules, etc connect here), and the Ulticontroller board.

Where are you located?


Does the printer make any noises at all when you try to power it on? Depending on which (if any) noise it makes, there are a couple of potential causes.

This is definitely a case where it's best off to work with your reseller on it.

Good Day,


Thanks for replying.   I am in New Brunswick Canada.  The only thing that happens is the exruder fan will turn on for approx 2 or 3 seconds,  then nothing happens.   The Olimex board has a red LED illuminated.  I attempted to flash the firmware again with instructions from the dealer and nothing happened (no LED flashed).  I suspect a bad Olimex board.

    • "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.
