just got my smoothie wired up yesterday for my kossel 2020 and i was testing everything out, i got the motors turning the right direction according to repetier manual controls, but when i went to home it, it moved all 3 axis down a few cm and stopped, so then i added ! to the endstops in the config file. then i tried again, but this time it makes a horrible noise and dosent move. has anyone had this problem before? i seem to remember my RAMPS board doing this but i cant remember for the life of me what i did to fix it.
Summary:homes in wrong direction for a second
