So everybody has helped me with, cracked print bed,bad thermistor and a few other things. I think I have one more issue I need help with and then I think I will be good. Because of my chipped print bed, I am using an extra pane of glass with blue tape. Now when I home everything the print head is scraping across the tape. I haven't started a print yet, because I don't want to ruin my machine.. Any ideas?
