Build Certification

Introduction

The kit in its fully prepared form requires no soldering, and only these tools. A cordless drill is recommended for the 6 mm bolts for speed:

1. 5 mm hex bit - for tightneting all 6 mm screws
2. Philiph screw driver - for power supply and MOSFET connection
3. 3 mm flathead screwdriver - for RAMPS connections to terminals; for taking out belt plugs
4. Pliers - for tigthening 6 mm and 3 mm bolts, and for tensioning the belt.
5. Side cutters - for cutting zip ties off

Supplies needed:

1. Magnets + JB weld + JB weld spreader + JB weld mixer - for building frame
2. Crazy glue - for attaching cable chain and end stops
3. Electrical tape - for fixing wires to frame and bundling them
4. Silver sharpie - for marking plugs
5. 0.4 mm needle - for unclogging nozzle
6. Sample PLA filament for initial printing

Procedure

Document on your log as Your_Name Kit Build with total of 18 pictures and 14 times. Ex. Sara Kit Certification

1. Build frame. 3 detailed Finished Pictures showing the amount of epoxy used on inside bottom, inside sides, and inside top. Time.
2. Build Y Left Axis twice. Finished Picture from the side opposite of the motor. Time.
3. Build Y Right Axis twice. Finished Picture from the opposite side of the motor. Time.
4. Build X axis. Finished picture from motor side. Time.
5. Glue first cable chain piece onto the carriage as needed.
6. Glue 2 endstops to X and Y axes as needed.
7. Build extruder assembly. Finished picture. Time.
8. Build heated bed (PEI addition + twist white wire around red. Finished picture from both sides. Time.
9. Build control panel. Finished picture from both sides. Time.
10. Mount Y axes and Z axes. Finished Picture. Time.
11. Mount the X axis. Finished picture. Time.
12. Mount heated bed. Finished picture. Time.
13. Mount extruder. Finished picture. Time.
14. Do cable chain and all wire routing and tidying. Finished picture. Time.
15. Mount spool holder and filament. Finished Picture. Time.
16. Print Cube while tethered to the computer. This provides a quick test of printer performance, and allows for fine tuning of the first layer. Start with Z offset of -1. Save into memory using LCD. Fine tune the first layer on the fly to get a good print. Add this babystepping value to the Z offset and save in memory to fine tune the first layer - the printer is good for production printing at this point. Print the test cube again - and show that without any adjustment - the print is correct. Take picture of the new Z offset on the LCD, and take a picture of the first layer to show a good print start.
17. Begin measuring time for file generation towards first print. Upload .ini file for this printer to your certification page on your log.
18. Generate 3DBenchy gcode. Compress and Upload your 3DBenchy gcode to your certification page.
19. Insert SD card with test 3DBenchy. Print at normal speed. .
20. Take 8 pictures of your first 3DBenchy.
    1. top for layer quality
    2. bottom for first layer adhesion
    3. front to observe symmetry
    4. back for fine letters and symmetry
    5. right side for overhang quality
    6. left side.
    7. Finally, the length (60 mm) measurement
    8. ...and width measurement (31 mm)
21. Make any adjustments on your printer if needed, print another Benchy, and take the same 8 pictures again.
22. Production - start a production print of 16 motor pieces and print successfully at 100% speed. The printer can ship once this print is done without any defects.
