If your laser arm derails, it may have been obstructed. So we'll start by checking for obstructions, then place the laser arm back on its track.
- Turn off your Glowforge
- Check around the side rails for any obstructions or debris caught in the belts. If you find anything, remove it.
- Try gently sliding the laser arm towards you, moving one side, then the other. Whether or not that works, continue to the next step.
- Placing one hand in front and one in back, gently lift up the laser arm on the right side, near where it’s off the track. Make sure your hands grip the metal bar, not the tube itself.
- While lifting upwards, roll the laser arm toward you, then farther away a few times. Your goal is to straighten out the arm, so that it’s parallel to the front door. It will pop back onto the track where it belongs.
- Once it’s on the track, place one hand on each side of the laser arm (left and right now, rather than front and back) and roll it to the center of your Glowforge. Then roll it back about 3 inches (7.62 cm), forward to center and then 3 more inches (7.62 cm) towards you, and then do that a few more times.
- Move the printer head to the approximate center of the laser arm.
- Turn your Glowforge back on and continue printing.
- If you find that your prints are not square after putting the laser arm back on the track, you may need to follow the instructions here to bring your unit back into square.
