I recently got my Monoprice Select Mini 3D Printer to work after about a month of inactivity, and I have run into a bunch of newfound problems lately. First, my microSD chip that I was using to save my gcode files onto wasn’t working, so I then got a new one, and all worked fine. However, whenever I clicked “Print” on the printer, it went to the screen where it said it was printing, but nothing was moving. Keep in mind that I did get the printer to print two things the day prior to the newfound problem. Could somebody please tell me how to get the printer to print again?
back to basics…
pull and reload filament, use low density card, format the cards on a regular basis, rename the file from filename.gcode to filename.g
then call tech support
