1 BIGBOT ASSEMBLY INSTRUCTIONS 1/18/2017 V0.5

2 FOREWORD: PLEASE TAKE CARE WHEN HANDLING THE GANTRY. THE ASSEMBLY SHOULD BE HANDLED ONLY BY THE ALUMINUM FRAME, AND AVOID TOUCHING OR LIFTING FROM THE BEARING RAILS, X AXIS, LCD, OR THREADED ROD. ALSO, THE CABLE CHAIN WAS PURPOSFULLY DISCONNECTED IN SOME AREAS FOR SHIPMENT. THEY MAY APPEAR BROKEN WHEN THEY ARE NOT. YOUR PRINTER IS REPRAP, WHICH STANDS FOR "REPLICATING RAPID PROTOTYPERS". THIS MEANS IT CAN PRINT THE PARTS THAT ARE CUSTOM FOR THIS MACHINE, AND OTHERWISE USES STANDARD COMPONENTS. THIS ENSURES YOUR MACHINE CAN REMAIN OPERATIONAL FOR YEARS TO COME. MANY REPRAP PRINTERS HAVE NOT KEPT TO THIS DEFINITION, BUT THIS PRINTER DOES. IF IN THE FUTURE YOU NEED PART REPLACEMENT, YOU ARE NOT LIMITED TO ONE COMPANIES PARTS DESIGN OR SUPPLY, AND CANNOT BE TAKEN ADVANTAGE OF BY A BRANDS MARKETING AND SALES TACTICS. PRODUCT SUPPORT: SUPPORT IS PROVIDED WITHIN THE BOUNDS OF THIS MACHINE'S PROPER OPERATION. ONCE YOUR MACHINE IS UP AND RUNNING, WE HIGHLY ENCOURAGE YOU TO BE AN ACTIVE MEMBER OF THE REPRAP COMMUNITY AT WHICH PROVIDES THE MOST COMPREHENSIVE SUPPORT AVALIABLE. MORE REPRAP PRINTERS ARE IN OPERATION THAN ANY OTHER PRINTER "BRAND", SO IF YOU NEED INFORMATION, ONE CAN BET IT WILL BE DOCUMENTED IN THEIR FORUM'S. IF YOU FIND A BETTER WAY TO DO SOMETHING, PLEASE HELP OUR OPEN-SOURCE COMMUNITY BY TELLING OTHERS!

REMOVE WOOD BED LOCKING BLOCKS. 1.3 CAREFULLY LIFT THE UPPER GANTRY ASSEMBLY BY THE ALUMINUM FRAME MEMBERS AND REST ON LOWER FRAME. USE THE SCREWS AND NUTS ASSEMBLED TO THE BACK OF THE GANTRY TO FASTEN GANTRY TO THE METAL ANGLE AS SHOWN BELOW. DO NOT MOVE THE CORNER BRACKET, AS IT IS IN THE APPROPRIATE POSTION. TIGHTEN BOTH SIDES. 1.4 TIGHTEN Z LOWER MOUNT BRACKET TO ALUMINUM FRAME. USE SCREWS AND NUTS LOCATED IN T-SLOT FRAMING BY LOOSENING SCREWS AND SLIDING THE NUT TO ALIGN IN THE APPROPRIATE MOUNTING HOLE. IT CAN BE HELPFUL TO USE AN ALLEN WRENCH OR OTHER SMALL STICK TO PUSH THE T-SLOT NUTS INTO ALIGNMENT WITH THE MOUNTING HOLE. IT CAN ALSO BE HELPFUL TO USE ONE OF THE TALL SIDE OF ONE OF THE EXTRUDER BOXES TO HOLD THE X AXIS ASSEMBLY UP WHILE TIGHTENING THESE SCREWS. TIGHTEN BOTH SIDES.

INSERT ENDS INTO RECIEVER IF NEEDED WIRE TIE LOOSE WIRES USING ZIP TIES FOUND IN BOX ENSURE CARRIAGE IS LIFTED SO NOZZLE TIP IS ABOVE THE BUILD PLATFORM, THEN MOVE BUILD PLATFORM AND X AXIS BY HAND THROUGH THE FULL RANGE OF MOTION. ENSURE THE LIMIT SWITCH "CLICKS" AT ENDSTOP POSITIONS TIGHTEN BELTS IF NEEDED. EACH BELT SHOULD SHOW NO "BOUNCING" OF THE TIMING BELT WHEN MOVING THE MOTOR PULLEY BY HAND. GENERALLY, THE TIGHTER YOU CAN GET THESE BELTS THE BETTER...VERY UNLIKELY YOU WILL CAN STRETCH OR BREAK ONE OF THESE BY HAND. IT IS PREFERRED THAT THE BELTS BE TIGHT ENOUGH TO HEAR A LOW BASS NOTE IF THE BELT IS STRUMMED.

7 2.0 TEST ELECTRONIC SYSTEMS 2.1 PLUG IN AND SWITCH PRINTER ON. 2.1 ENSURE BED REMAINS COOL. TURN OFF IF IT WARMS. 2.2 REMOVE PROTECTIVE FILM COVERING BUILD PLATE. 2.3 APPLY YOUR HEATED BED MATERIAL, TAPE, OR ADHESIVE OF YOUR CHOICE. PET, KAPTON, OR PEI ARE RECOMMENDED BUILD PLATFORMS. IT IS NOT RECOMMENDED TO PRINT DIRECTLY ON THE ALUMINUM SURFACE, AS THIS WILL RESULT IN NICKS, SCRATCHES, AND ABRASIONS. 2.4 NAVIGATE LCD MENU TO TURN ON THE HEATED BED (IN EXTRUDER MENU). ENSURE TEMPERATURE IS STABLE. 2.5 NAVIGATE LCD MENU TO ENSURE THERMISTORS ARE ALL READING CORRECTLY. IF "DEF" IS DISPLAYED, THERE IS A BAD CONNECTION. 2.6 TEST X, Y, AND Z LIMIT SWITCHES.
