Component tests
Test | Description | Target | Tolerance |
---|---|---|---|
Motor length | Measure the length of the motor body (no encoder or shaft) using digital calipers. | 47.3mm | +/- 0.5mm |
Motor housing fit | Mount a motor to the cross-slide plate with a horizontal motor housing. Mount a motor to the z-axis motor mount and cover with the vertical motor housing. |
Motor should fit inside housing | N/A |
Shaft | Mount a GT2 pulley onto the motor shaft according to the FarmBot system design. | Pulley should mount as expected | N/A |
Shaft length | Measure the length of the motor shaft using digital calipers. | 22mm | +/- 0.5mm |
Mounting holes | Mount a motor to a cross-slide plate according to the FarmBot system design. | Screws should thread into motor as expected | N/A |
Motor operation | Connect the motor to a Farmduino and issue a movement command. | Motor should operate as expected | N/A |
Encoder | Connect the motor and encoder to a Farmduino, issue a movement command, and inspect the encoder position in the web app. | Encoder position values should update as expected | N/A |
Engraving | Inspect the FarmBot logo engraving. | Must not be stretched | N/A |
