So I've had my Maker Select III3 Plus for about a year and it's been wonderful up until 2 weeks ago. I've never heard of anything like this. Whenever I connect the printer to the USB port, the hotend begins to heat up. Now, the computer recognized the printer and I can control it completely except for the hotend temp...it tops out, shuts down for a second, then repeats. S3D, nor any other host soby Rate8x - Prusa i3 and variants
