In this lesson we’ll walk through adjusting the tension of the Epilog Fusion M2’s x-axis belt.
Remove Panel
Shut off the laser and remove the power cord from the machine.


Remove the top access panel on the left side of the machine by using a 5/32” hex key to turn the black panel locks ¾ of the way counter-clockwise.

Adjust Belt Tension
Use a 7/64” hex key to loosen the x-axis pulley mounting screw located in front of the x-axis belt, accessible through a circular hole in the top of the x-axis assembly. Then loosen the second mounting screw located in the open channel behind the x-axis belt.


Next, loosen the two x-axis pulley mounting screws located on the top of the x-axis assembly.


Use a 5/32” hex key to adjust the tensioning screw accessible from the end of the x-axis assembly.

Loosening the screw will loosen the belt. Tightening the screw will tighten the belt.

Once you’ve achieved the ideal tension, use a 7/64” hex key to retighten the two pulley mounting screws.


Reinstall Panel
Replace the top access panel on the left side of the machine, using a 5/32” hex key to turn the black panel locks ¾ of the way clockwise.


Plug the machine in and turn it on.
