I am using a Prusa i3 printer and just recently I have been having problems with the first layer. Here is a picture of what it looks like.
I have tried levelling the bed and it seems to be level. I was using a glue stick before but it started bubbling on that, so I switched to tape and that worked once but it is not working now. I wiped the tape with rubbing alcohol and it happened again.
What else can I do to get the first layer right?
