Rigidbot Power Supply Upgrade - Back plate system

thingiverse

This is the front plate mounting system for the 24V 550W ATX style power supply upgrade for a Rigidbot or Rigidbot Big (RB1 or RBB) while still utilizing the original main board. These front plates provide a universal system for attaching the new upgraded power supply and connecting it to the original stock main board through a Kycon adapter on both the Regular and the Big models. There are three STL files: The Power Side, the RB1 Main Board Side, and the Middle. The power supply and RB1 board sides work on either size of printer, while the middle section is required only for the Big model. Designed to be printed on a 10 X 10 bed so that a regular printer can print its own upgrade. A big can fit all three parts at once. The files are Cura scaled and oriented for printing. The rest of the kit parts can be found at the link below with additional pictures and instructions: http://www.thingiverse.com/thing:1712645 Note the print and post-print instructions below: Print Settings: Printer: Rigidbot 2 Rafts: No Supports: No Resolution: 0.1 - 0.2 mm Infill: 20% - 22% Notes: These are precision-fit parts. Use of calibrated filament is strongly recommended for best results. I use the following calibration clips: http://www.thingiverse.com/thing:1037301 These prints work best on a well-leveled flat aluminum bed wiped down with Windex and covered with 3M blue painters tape. I have had no warping or tape peeling up while printing many sets of the previous iteration of these. At 0.1 layer resolution and 22% fill, the parts are very solid and create a very sturdy support system. A sharp 3/4" chisel with the bevel side down pops the prints off the bed as you work around the edges at 40C reheat and helps avoid damaging the tape. Post-Printing: Assembly Instructions: Use the M3 bolts that come with the printers for assembly if the plate sections. They will self-thread in the holes. The bottom back tubing needs to be removed from the printer, and the Anchors from the kit tagged above need to be inserted in the ends where it used to mount. Review the pictures in that post. Carefully pre-thread an M4 bolt into the 2 holes on the shelf where the main board cover will rest. Mount the board cover base with M4 bolts onto the back plate first but do not tighten it all the way down. Attach the back plate assembly to the back of the printer. Again, do not tighten all the way down. Mount the board cover base plate on the side rail and square it up. Now tighten down all the bolts. Place the main board in its cover and position the top cover and tighten the bolts. Mount the power supply onto its back plate. Plug the Kycon connector into the main board and snap the 4 Pin connection into the key on the back plate. The 4 Pin plug from the power supply will plug into the back on the other side. Insert the feet into the bottom of the Printer. Your power supply upgrade is now complete. The Kycon adapter and jumper can later be removed, allowing you to plug the power supply directly into an upgraded 4E3D main board. See http://www.thingiverse.com/thing:1712645 as referenced above for details. You can print the main board part from http://www.thingiverse.com/thing:1841137 and it will mount on either printer design. The assembly is quite strong and very solid when mounted on the printer back. The M4 bolts that are used for mounting the stock back cover are still used to mount these plates.
