Case and mount for CYD-Klipper, an easy to deploy and use screen based around ESP32-2432S028R AKA Cheap Yellow Display.
Artifact list:
- M3x10 screw, preferably Allen
- M3 nut
- CYD with its accessories (pen, power cable)
- either of:
- 2.54mm XH2.54 6-pin male terminal
- a pair of 2- or more wire connectors (plug+socket), any kind.
Printing:
Print wedge and swivel on their sides for best durability. Swivel may require Brim (and trimming it thoroughly). Top will have a nicer bottom of the notch with standard supports enabled.
Assembly:
- Get CYD-Klipper to work correctly without the case. Set screen to "Rotated 180 degrees"
- Unplug and remove the original display; free its cable. You may want to print an end cap to close the rail.
- Optionally swap its plug to whichever you got if you don't have the XH matching the original.
- The cable with "LCD" tag is +5V, the one on opposite end is GND (use multimeter to make sure though) - Using the original clips lead the cable through the underside of the middle rail to the front.
- Solder the socket to the CYD power cable, matching polarity of the plug; red +5V, black GND, do not connect the remaining two (trim them short next to the board side plug).
- plug the power cable into CYD, insert it into the case and close the back (USB to USB slot; 2 small holes in the back go above BOOT and RESET buttons). You'll need to bend the back a bit for the latch bars to slip into the slots in the front. Make sure the power cable goes out through the big center hole.
- Insert the swivel under the wedge's clamp, V notch on the swivel goes opposite to / notch on the wedge, [ notch goes opposite to ] notch.
- Insert the nut into its socket in the swivel (between the swivel and the wedge)
- Screw the screw in just a little bit to hold the nut from falling out
- Attach the assembly to the profile holding the belt idler in the middle of the printer
- Make sure the [ ] notches grip the profile well, then tighten the screw enough that it won't come off the profile but sits only loosely.
- Latch (snap) the CYD case onto the / and V wedges; pen below, thread the cable through a side next to the wedge.
- Tighten the screw until the CYD doesn't wobble at all. Don't tighten it all the way, you'll break something.
- Connect the power socket and the plug and tuck them away.
- Add the stylus.
FreeCAD file attached, if you want to adapt to the USB-C version of the board or something along these lines.
