  2. Hi gr5, Thanks for getting back to me. It had the green board, however it blew up!

It now has a generic board from AliExpress, which is labelled Ulimaker,com which the same connections as the green board and a new Arduino and stepper drivers, carefully placed in the correct direction. The print head does have the tiny circuit board on top, yes. The HBK does work and heats, it’s current temperature reading is 40c, although I am currently setting i
  3. I own the Ultimaker Original HBK, however, I am facing a couple of difficulties with it, which I am hoping perhaps someone could help with? The first is that the thermoster readings are way off on both the Heatbed and the Extruder heat. Even at rest the best I can get is 40 degrees for the HB and 59 degrees for the extruder. For both of the readings; I have tried the Ultimaker Firmware builder and a Marlin build with a new board and Arduino Mega 2560 and all combinations of the thermostats and thermoster, and unfortunately the 59 degree reading on the hotend came through setting the “10K

  9. Hi, Just got a UMO with a heated bed mod in it. I’m a complete newbie so please be gentle with your replies, however, I wanted to know whether it is possible to put a UM2 Motherboard into the UMO and if so what other adjustments I would need to make? Any advice however basic or complex welcome. Many thanks in advance.
