D3D 1612 Product Testing

Final Quality Control Procedure

Done once the entire machine is assembled together and ready to run. Tests for all parts being secure, proper tightening of bolts, proper dimensions of cut parts, and all other parts of structure, prior to functionality testing in the Testing Procedure below.

Testing Procedure

1. Upload firmware to the RAMPS board.
2. Turn power supplies on, make sure green light turns on.
3. Verify that the fan is turned on on the extruder
4. Power light lights on the Arduino
5. Fan turns on on the 24V power supply.
6. Verify that red light on MOSFET turns on
7. Move axes by hand to see there is no stuckage
8. Moving axes by hand, record the range of movement for X, Y, and Z - ______________
9. Home x
10. Home y
11. Home z - but don't adjust probe yet.
12. Set extruder temp to 205C
13. Verify that red light goes on, and that the temperature on the Cura monitor is flat (stable) once temperature is reached.
14. Load filament
15. Extrude filament once machine gets up to extruder temperature
16. Home X and measure range of motion from beginning up to software endstops. Compare X motion via the Cura interface and the maximum motion obtained in Step where axes are moved by hand to determine their absolute highest motion. The difference should be +/- 3 mm
17. Home Y and measure the same for Y. Motion tolerance should likewise be +/- 3 mm
18. Touch the head of the inductive sensor, and see if it is triggered (red light on it should turn on).
19. Raise the build platform manually to verify that it moves up and down easily. It should either hold or drop slowly by itself when raised above its lowest point.
20. Raise the
