Elegoo Mars 3 Endstop Modification

Step 1

Printing the Endstop Spacer

The Elegoo Mars 3 does not have enough z-height adjustment to compensate for the thickness of Fula-Flex, and a printable spacer will be needed.

Make sure to print and test the spacer before you install the magnet! Once installed, you cannot use your printer without the spacer.

Installing the Spacer

Remove the two screws securing the trigger arm located beneath the gantry.

Re-Install with the printed spacer between the trigger arm and gantry as shown.

Now that the spacer is installed, we can move on to general installation.
