Yeah based on the looks the only other way is to 3D print parts that would fit in the short pillars that hold up the bed and do it that way (with screws to turn it up and down)
here is a video that I found https://www.youtube.com/watch?v=5iOSFc2H9bY if you scroll to around I think the 4 minute mark it shows the auto levelling. Though I guess this works into my next question (sorry for all the questions)
If I guy it from 3dprintersonlinestore, and I don't like it, or say the auto levelling doesn't work, can I return it? According to their site, if the item doesn't work as intended, seems like I can, but I can't quite see how many days I have to do so. In addition, if I just don't like the thing (say low print quality, which would be weird if that's the case, but let's just say that's what happened) can I also return it? Thank you very much!
