Also got a pre-built Proforge 3 with DSH. After an initial difficult start, I got it working (more or less). What's working: Cura AppImage for Ubuntu 20.04. Octoprint with integration into Cura. Benchy PLA single extruder was ok. Not the best quality but my PLA was old. Dual extrusion calibration. I had to set y and z offset for the tool#2. Simple and small dual color prints below 1h printing time. What's not working well so far: More complex dual color prints. It starts well, but then I get one or both hot-ends clogged. When this is happening I have to remove the bowden tube in order to pull out the filament manually. I suspect this has to do with reaction distance (7mm and 12 for tool change) and print temperature. Could also be a bad combination of PLA and the all-metal hot-end. Sometime my filament breaks between the extruder and the hot-end. Probably bad-quality / old PLA... I will try to reduce the retraction speed. My other printer with a bowden extruder has no issue. Bugs in the firmware. E.g. sometimes resuming a print (from Octoprint) starts at the top-right of the print area and I have to abort the print. Other: I had to calibrate both extruders. One of them was quite off (11.8 mm extruded instead of the 10mm requested). Skipping layers and noisy movements. => fixed by oiling all the linear bearings. In general this printer is very loud... Hot-end fan is loud and there is one fan in the electronic part that is extremely loud. Not sure if it is the side fan or the one from the PSU. I will look into upgrading the fans as soon as I'm confident with the print quality and reliability. The x and y steppers are also loud. I do not notice a difference if I activate or deactivate the StealthChop mode of the Trinamic drivers from the touchscreen. Anyone could provide feedback here? The z steppers are not able to support the build plate weight (MIC-6) when not powered. Therefore you have to manually level the bed after each shutdown. Then, perform a UBL before the first print. I know about the z-synchronization upgrade. I'm too lazy to implement it for now. I think this should be by default. Fan shroud was not delivered. The 2nd build plate I ordered as spare part was not delivered.
