Step 1 Disconnecting cables

⬢Take a look from the back of the printer.

⬢On the electronics box (Einsy base), release the middle screw on the box to open the door.

⬢Release all M3 screws on the cable holders on the box.

Avoid cutting the cables!!!

⬢If some of the cables are secure with zip ties, carefully cut the zip ties.

⬢Disconnect all cables from the EINSY electronics board.

⬢Some of the cables have a safety latch on the connector. Press the latch before disconnecting.

⬢Using the Philips screwdriver, loosen all the 6 power terminal screws and slide out all the power cables.

Step 2 Removing the electronics box

⬢Loosen the M3 screw in the bottom of the electronics box fixing the printed case to the frame. No need to remove it at the moment.

⬢Loosen the top M3 screw inside the box. Push the 2.5 Allen key through the most top vent opening to reach the screw.

⬢Slide out the box to the right side and remove it from the printer.

Step 3 Removing the einsy-door

⬢Release and remove all four M3 screws together with the einsy-door.

Most of the following pictures are taken on the latest version of the printer frame. The frame has hexagonal recesses on its back side. This is just a design element. The latest frame design is functionally identical with the previous ones.

Step 4 Removing the heatbed

⬢Release all nine screws securing the heatbed and remove the heatbed from the printer.

⬢After removing the heatbed, there are nine unattached spacers on the Y-carriage. Place them in a separate place to avoid confusion with similar parts. You will no longer need this part.

Step 5 Removing the heatbed cable cover

NOTE: If you have already purchased a new heatbed, you can skip disassembling the old one and go to the next step.

This part may vary slightly in the design of the cover, location of the screws and number of the screws.

⬢Remove the screws fixing the cable bundle.

⬢Remove the screw securing the cover. From the underside, grasp the middle M3nN nut with the pliers while loosening the screw.
