- Add Arduino-Nano to case, insert it into notches a slowly push usb connector down. It should be quite tight fit
- Wire up power connector, power switch, buck converter and relays
- Fix power connector with super/hot glue in case
- Add cables to buck converter output and mount it slowly to the case, it should be tight fit
Buck-converter
- Connect motor to relays and mount it to case, fix it with 6 screws
- Cleanup wiring and secure relays to case with few screws
Motor + relays
- Add Rotary encoder next to motor and fix it with screws or nut
Rotary encoder
- Insert nut & screw into motor pulley and secure it on motor shaft
- Add timing belt with encoder pulley onto encoder, readjust encoder position if belt is loosen or too tight
Motor/Encoder pulleys
- Wire up rest of the electronics as shown in the wiring diagram
- Fix dupont cables for display + keypad with super/hot glue into cable connector part and afterwards fix it with super/hot glue to case if needed
Finished motor case
- Add hexagonal rod and slowly insert it into table, if needed adjust hole for rod hole with original lever
- Fix mounted motor case with 7 screws to table
