9. Bed Carriage
We now move onto installing the Printer Bed. With FT Enderwire we have a new way of running the Bed and Thermostat wiring using an Umbilical.
First off lets install the M3 Threaded Inserts for all the parts in this section. 4 x M3 Threaded inserts for the 2 [a]_y_belt_clip_x2 and 5 x M3 Threaded inserts for the [a]_y_chain_bed_mount_generic as shown below.
Next lets mount the 2 halves of the bed carriage. Do take note that there are M5 Nuts that need to be preloaded as you attach the carriage to the linear rails - you wont be able to insert these M5 nuts later so ensure they are in as you begin to mount. Also notice that there is an F imprinted on the right piece, this needs to face the front of the printer.
Next secure both sides of the bed carriage to the linear rails using 8 x M3x8 SHCS screws.
We are now ready to attach the Y Belt we ran earlier to the Bed Carriage. pull the belt and place it on the inner side of the bed carriage and place a belt clip behind the belt with the groves facing the belt. Hold in place and screw in the 2 x M3x12 SHCS screws loosely. Repeat for the other side. Once in place pull the belts so that they are somewhat tight and tighten the 4 x M3x12 screws. You can now begin to tension the belt using the front Y tensioner screw.
Next we will install the mounts that will hold the PG7 flex glands both on the bed and the deck panel.
- Install 2 x M5 T-Nuts into the extrusion where the [a]_y_umbilical_frame_mount will be screwed into place
- Attach [a]_y_umbilical_frame_mount to sandwiched between the deck panel into the M5 T-Nuts using 2 x M5x10 BHCS screws
- Attach [a]_y_chain_bed_mount_generic to y_axis_bed_carriage_b using 2 x M3x8 SHCS screws
- Attach [a]_y_umbilical_bed_PG7_mount to [a]_y_chain_bed_mount_generic using 3 x M3x8 SHCS screws
- Install 2 x M3 T nuts into the center extrusion as shown below
- Secure [a]_y_axis_ls_mount to the extrusion using 2 x M3x8 SHCS screws
- Install the Y limit switch to [a]_y_axis_ls_mount using 2 x M3x8 SHCS
