Hi there,
I decided to start building the DXU upgrade for my UM2+ ordered al the hardware parts and polycaronate for printing all the parts. The only doubt I had was that the 35w heater would be on the light side, so I replaced that with a 40W heater set. It might be too much as well resulting in a less sable temperature, but we will see. As soon as all is finished Ill share the results. Furthermore I managed to get most of the parts directly from Aliexpress and some were ordered via Superuser (good taobaoagent) when there was a substantial price difference for the same quality. the price for all was around 110 euro's.
Best,
Crispijn
