If you are having trouble with Pro Passthrough, the printer head is not moving, or you receive an error message when you run Set Focus, it could be a problem with the printer head connection. Follow these steps to check and readjust the connection.
Turn off your Glowforge
Follow the steps on our Replacing the Printer Head page
This will guide you through properly disconnecting the printer head from the carriage plate.
Take photos of the gold pins and the bottom of the printer head
Take clear photos of the gold pins inside the printer head where you just unplugged the wire ribbon, and the bottom of the printer (see examples below):
Replace the printer head on the carriage plate and reconnect the wire ribbon
Refer back to our Replacing the Printer Head page for exact steps.
Take a photo of the large circuit board
Pull the laser arm all the way forward. Take a clear photo of the circuit board on the inside left of your Glowforge. Please make sure your photo includes the white ribbon connection highlighted by the arrow in the example below.
- Take a photo of the small circuit board
Just to the left of the large circuit board in step 5 is another small green circuit board. Take a photo similar to the example below:
Take photos of the door and left side rail
Take photos of the left, inside of the front door and the left inside side rail, like the examples below.
Left Side Front Door
Left Side Rail
If needed, reconnect the circuit board cable
If the cable indicated above with the red arrow (see Step 5) appears to be loose, please reconnect it and try printing again. This cable should 'click' back into place.
Try a print
Turn your Glowforge back on, and try another print.
