Wire and Connection Testing
Test motors before wiring, never connect or disconnect anything (except possibly USB) with the power on. After testing motors, all motors are tested in a configuration with a solenoid actuator, limit switch and relay switch. All the components are configured/controlled individually using the tinyG controller. Motor->done Solenoid->Done
Tests and Refinements
The test version setup is developed using the old 3D printer.
Following tests and improvements are done using the test setups :
Test 1 :
| Problem Observed | Rectification |
|---|---|
| Correct Dimension of braille is needed. | New size and dots spacing are opted |
| Motor Vibration | Stepper motor parameter is adjusted. |
Test 2:
| Problem Observed | Rectification |
|---|---|
| Non uniform Embossing | Modify the bed orientation |
| Motor Heating | Current rating is adjusted |
Test 3:
| Problem Observed | Rectification |
|---|---|
| Less penetration | Proper thickness of paper is used. |
Test 4 :
| Problem Observed | Rectification |
|---|---|
| Vertically mirrored letter | The solenoid should engrave from upside down , so next version is developed. |
