Y platform skips

[dogma]

i cannot keep my y platform from slipping I have tried righting the belt and loosening the belt but 2-3 minutes in a print it starts shifting and you can hear it like the belt is slipping off the pulley. Any suggestions?

Your Y motor driver must have a low voltage, you can refer to the link here to check the voltage:

ok i fixed y drive...bearing holder clamp needed to be widened so the bearing could move more freely. Now my y and x go the wrong way for home. Y I turned the motor around to correct that problem but you cannot switch motor for x and I printed some letters and they were backwards. I read I need to change firmware and upload. Do you have a link showing where to download and step by step how to do this? I believe that is all i need to set my printer up. I love I got to put this thing together myself and is very fun.
