I put my Markerbot away a while ago and haven't used it because it was not able to make items big enough and it took a lot of time to look after - lots of tinkering, and not much making! Makerbot now have a newer plastruder called
the Mark 6. Unfortunately, it seems to be continuously out of stock! Also, I think I may have to upgrade my electronics board if I do upgrade, but I'll cross that bridge when I get to it.
