Laser Not Cutting Correct

Anyone know why the laser is adjusting over like this? It did it several times. I have it set on 3 passes and it keeps adjusting to the right after a pass.

I would start by checking the carriage plate belt tension.


Oh no, I’m sorry you’ve hit a snag.

To investigate further, would you please send me the following photos?

First, power off your Glowforge and remove the crumb tray.

  1. The belt under your laser arm with the head pushed to the left:
  2. The pulley under the laser arm on the right side from the front:
  3. The right side pulley under the laser arm from underneath:

Hey Jeremy!

Someone mentioned tightening the belts and DOD that. Have not had an issue right now since I have done that.
