Hi everybody, I've been lurking the UM community and forum for a while now, but just have to respond to this development. I love it, great job! Count me in for an update kit and simply name your price. Long story short: I run an UM2+ (upgraded UM2), I desperately need the soluable PVA support for my scale models and maquettes. I'm sick of chopping perfectly fine models up for reasonable print results and later stick them together again (and postprocess it all, often 'not helping' on the quality side). It has cost me days and days of work. Weeks if not months. No wonder I'm super excited about this solution. I have been looking around but couldn't find an answer yet. Maybe I'm just being stupid here, but I was wondering how possible interferences of the nozzle are accounted for, as the bed doesn't seem to move after swapping heads. When the (e.g. PLA) product is completely enclosed by support material, and this support layer is printed first (seems logical to me), it could be possible that the nozzle needs to pass the higher support wall, right? So this could mean, with bigger layer thickness, that the nozzle touches the support. Or am I missing something here? I'm sure you have figured something out, I just would like to understand this. On the gcode side; I'm sure there will be a custom plugin for this? Last but not least; are there any test yet with this system while using PLA + PVA? Keep up the great work!
