Ender 3 not printing

[jeff5 1]

Hello,

  I have had an ender 3 for over a year.  It will not start a print.  All functions seem to work with no problem. ex: auto home disable steppers, preheat pla.  Once i select a file to print it does nothing.

  I have searched through the forum and have not found the problem I have

Thank you

Jeff

* when i first had this problem i unplugged the printer and it worked one time.  I tried that again and it has worked again

Try re-formatting the SD card and blow out the card slot in the printer.  Have you ever used Cura to send a print over the USB?  If you have, and you know the computer and printer can communicate, then you can hook it up to the computer, start Cura, load a gcode file (or slice something) and go to the Monitor screen.  Try sending G28 from Cura and see if it the printer homes.

If that stuff doesn't work you can try sending M502.  That will do a full reset back to factory defaults.  You will lose your Home Offsets and Steps/mm calibration stuff.  You should be able to get those from the printer before you reset it and then you can just re-enter them afterwards.  When this happens though it's often the SD card.

Changing the SD card and blowing out the printer worked.  Thank you
