Hello all! I don't have a picture at the moment but I am having an issue with PVA. I JUST got the UM3 this week and made a test part with some various overhangs to test out the dual extrusion since I have never had it before. I used PVA as the support material so I could dissolve it of course, but during the beginning of the print, the PVA was oozing pretty consistently. About 1/10 of the way into the print it stopped oozing as much but never totally stopped for the rest of the print. Not a big deal if I am going to dissolve it right away I know but I was curious if there is a full proof way to stop this from happening at all. I saw a few threads on the subject but the content was still a bit off from the problem I am having. Any and all help is definitely appreciated ? Thanks!

I meant to say if you look at my LCD when it boots up, its EXACTLY like the picture. Graphics style, layout, and what it says. I checked every connection you pointed out and they were all fine. Also, my stupid original post got messed up too and the last few lines dont make sense. When I turned the machine on it did all that crazy stuff with the lights and steppers. When I plug it into my computer, the computer wont even see it so I can't update any firmware. Long story short, I dont want to invest too much time in figuring this out because my work is paying for it and fixing this is gonna be on company time. I just wanted to save a few bucks if I could.

I bought a replacement board from aliexpress instead of going through fbrc8 or something similar because why would I pay $350 for a board when its $100 on the other site.... Well I found out there might be a good reason for why to just buy through the partner company(s). I plugged the new board in and it turned on but looked just like the photo below. (The pic below is from an ebay listing; its not mine) So my question is this: A. Is it possible to still make this new board work? because when I plugged in to my computer, the computer didnt moving all of its steppers to the same frequency of the flashing LEDs. I assume it was due to the error code it was throwing. OR B. Do I need to just suck it up and spend the money to get the new board from a partner company?

Hello all, new to the forum. Have used my Ultimaker 2 for a few months as a packaging designer. I noticed one comment state that the new feeder stepper is only 200 steps per revolution vs the old one being 400. Can anyone explain why 200 is better?
