[Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade]

@dfrez yes I have read you got the same kind of troubles. I have ordered new magnet from the recommanded shop as the first set was included in the cheap Mark2 kit from China. Electronic stuff is ok but I was not enough cautious with magnets quality.

Hi

I have just finished the Mark2 conversion. What an amazing job you did guys ! 

So first of all I wanted to thank the team for sharing this and still supporting the community. 👍

 

I have 2 issues : 

I bought a UM2+ head set from china (quality OK) with 12v fans. With the fan control menu, the fans were producing very few air until 99% and then they were stopping a 100% ! Voltage was 24v a 100%, the fans are mounted in serie. In order to solve this, I had to change for 2 fans 24v in parallel...  Is it normal ? Maybe I have missed a recommendation !

 

The second issue is probably linked to my magnet provider as I suffer some head disassembly at Xmax/ Ymin location. Magnets not strong enough or extruder orientation not correct ? I have temporary improved it thanks to a bungee cord pulling the bowden tube to the rear... Any advice is welcome !
