NanoDlp Parasite box

thingiverse

The goal is to make it easier to connect NanoDLP to a typical LCD resin printer. - Parts Needed 1. Raspberry Pi 4/3B+ 2. MKS GEN L 1.0 (CAUTION: This board determines output voltage according to input voltage, 12V/24V; be aware of the PSU you choose.) 3. M3 bolts/nuts (various lengths), M2.5 bolts/nuts (various lengths) 4. Power switch (in my case, KCD1-101A; modify the switch hole size to use your preferred switch) 5. Push switch for Raspi shutdown (not required as it provides a shutdown option on Nanodlp) 6. 60x20mm DC cooling pan = case cooling fan 7. 5V DC to DC step-down converter (for Raspi power supply) 8. Soldering tool 9. DC input cable (select according to the PSU you choose) 10. 24V/12V PSU 11. USB C charge cable 12. Micro 5-pin cable 13. Micro/mini HDMI to HDMI cable/gender (to meet the specifications of your Raspi) 14. LCD LS055R1SX04+HDMI to MIPI (depending on the LCD you choose) 15. Nextion 3.2 Touchscreen (not required for a wired connection only) 16. Cable (for motor, endstop, LED, etc.) 17. Micro SD x2 (Raspi, Nextion TFT) 18. Neodymium magnets x4 (if attached to a printer case; replace with rubber support or double-sided tape) 3D Printed Parts Frame_01.stl x1 CASEBODY.stl x1 spacerM3.stl x10 LCD_cover.stl x1 Cover.stl x1 Assembly Sequence 0. Install Nanodlp on Raspi and load TFT on Next 3.2 (Note: https://www.nanodlp.com/download/); set up Next 3.2 (Note: https://www.nanodlp.com/forum/viewtopic.php?id=2069) 1. Insert a spacer between frame and board, then secure with M3 bolt. (Since the bolt hole in Raspi is smaller than M3, use the drill bit to enlarge the hole or use the M2.5 bolt. Secure the 5V step-down converter using a cable tie and double-sided tape. Fix it the way you want, depending on the type of converter you use.) 2. Cable Connection. 1) Connect DC input cable and power switch to the power input terminal of MKS GEN L 1.0. 2) Connect output terminal of 5V step-down converter to the power source of Raspi (direct connection to GPIO is not recommended). 3) Connect push switch for shutdown to Raspi (Note: https://magpi.raspberrypi.org/articles/off-switch-raspberry-pi) 4) MKS GEN L 1.0 output terminal connection: - Extruder -> UV LED - Cooling Fan -> Fan - 12/24V output -> 5V step-down converter, case cooling fan - Z endstop -> Z endstop - Z motor -> Z motor 5) Assemble frame, power switch, shutdown switch, and Nextion 3.2 to the CASEBODY; take the cable out of the case and arrange it well. Watch out for cable kinks and collisions between parts! 6) Cover and secure the case cooling fan. 7) Done! 3. Marlin upload to MKS GEN L 1.0 (Note: https://www.nanodlp.com/forum/viewtopic.php?id=2325) 1) Configuration_adv.h //#define NANDLP_Z_SYNC (disable annotation for that item) 2) Configuration.h #define TEMP_SENSOR_0 1 (set thermistor type to 998 which means it will always read 25degC) #define THERMAL_PROTECTION_HOTENDS // Enable thermal protection for all extenders #define THERMAL_PROTECTION_BED // Enable thermal protection for the heated bed #define THERMAL_PROTECTION_CHAMBER // Enable thermal protection for the heated chamber (all of these items are annotated). To prevent Thermal Runaway) 4. Set Nanodlp - Set this part according to the hardware you want to use. Please refer to the image for the settings I used.
