I am printer with my tevo tornado and I have been trying to print this large letter F for a long my time now and I keep having the same issue and I’m not sure what is causing it. The layers on the print are going from thick to thin on the initial few layers and once it gets to the Infill I have to stop it because it’s not working. I’m not sure if it’s something to do with me being too close to the bed or clogging. Any suggestions would be great!!!
