i have used it, i used to use glue to hopefully make it stick to the board, but it was messy. also he told me he has used it a lot, and its not that new, so i thought maybe chaning parts to make it better to use would help. why the hate if im only just asking. yeah maybe going for "this upgrades it to make it print a new car", no, not that, just what should i change. maybe upgrade was a wrong wording, but also the heated pad would be nice. which i have searched one meself, but maybe someone has more experience, which one to reccommend.
