JG Aurora Z603S Infrared Sensor Upgrade https://youtu.be/L8FqyaKwRao This upgrade only works for the later GREEN motherboard. WARNING WARNING MAKE SURE YOU DOUBLE CHECK YOUR CONNECTIONS POSITIVE to POSITIVE NEGATIVE to NEGATIVE SIGNAL to SIGNAL I added an extra 3 pin socket to my green motherboard (PIN 18). This is where the IR sensor is plugged in. Check the image for correct connection. The original opto Z min endstop has been disabled in firmware as I intend to use it as filament sensor input in future. You can plug your new IR sensor into Z min if you wish, saving soldering. If you do this, you will need to change #define Z_MIN_PIN in PINS_Z603s sketch back to pin 19. WARNING WARNING Description Autobed Level Addition to JG Aurora Z603S 3D Printer Items You Will Require Infrared sensor - https://miscsolutions.wordpress.com/mini-height-sensor-board/ 3 wire servo extension lead (2 x 1m in length) Files Included Mount STL Cover New X endstop trigger Firmware 1.1.8 Marlin To do this modification, you will need to update main board's firmware using Arduino IDE software. There are plenty of YouTube videos showing how to do this; just search for "update marlin via arduino ide". You will need to open your machine up and feed 3 wire connector around the machine. The sensor uses a new 3 pin connector which I soldered too on main board. If you don't want to do this, you can alter firmware to use Z minimum endstop connector. See above for changing to pins info in firmware required. The current z endstop needs to be removed. Just unscrew it from side frame and hide it below. You can always go back if needed. I've already configured the firmware to use this sensor, so you will only need to flash it. I have enabled eeprom on board, so you can save bed levels... but I would level at start of every print just to be safe. To level, you will need to add some gcode lines to your start gcode script. There is normally a tab/section in your software; the lines you need to add are: M851 Z-3.1 ; Z Offset M500 ; Save to Eeprom G28 ; Home G29 ; Level bed etc... The Z offset can be set above. Z-1.0 = 1mm... so if you want to lower head then you would do... M851 Z-1.2 ; Z Offset This would then be 0.2mm closer than before. Let me know how you get on... Any questions please ask away and don't forget to like this :-) I would also recommend adding the following to your gcode start/stop script in your preferred printing program. START SCRIPT M851 Z-3.1 ; Z Offset <--- NOTE you will need to change this value M500 ; Save to Eeprom G28 ; home all axes G29 ; Level bed G1 X10 Y10 F9000 ; get ready to prime G1 Z0.3 F6000 G92 E0 ; reset extrusion distance G1 X240 Y10 E24 F2000 G1 X250 Y10 F180 G1 X260 Y10 F5000 END GCODE G1 X0 Y180 F3000 ; Move bed/head G1 Z170 F3000 ; Move bed/head M106 S0 ; turn off cooling fan M104 S0 ; turn off extruder M140 S0 ; turn off bed M84 ; disable motors Then disable SKIRT or BRIM as you won't need it anymore.
