Note : Please use the red stepstick drivers A4988. The purple DRV8825 were used in a previous version.
Fix the standoffs on the electronics mounting plate with M2.5 x 4mm Screws
Use M3 x 4mm Screws to fix the mounting plate in the electronics box.
M2.5 x 4mm Screws
M2.5 x 4mm Screws
Note : Please use the red/green stepstick drivers A4988. The purple DRV8825 were used in a previous version.
BE CAREFUL : If using the red/green stepsticks, their potentiometer should be facing up. (Reverse direction for the purple ones).
BE CAREFUL : If using the red/green stepsticks, their potentiometer should be facing up. (Reverse direction for the purple ones).
Use two 3 connector lever nuts in order to share the 12V input between the RAMPS and the UBEC tension divider.
Use two 3 connector lever nuts to share the 5V input for the Raspberry Pi and two 5 connector lever nuts for the encoders power.
Note: you can simply invert the orientation of the motor 4 pin connector in order to invert the direction of the motor. This can also be done programmatically on farmbot.io (Device > Hardware)
The encoder cable colors are the following : A yellow B green A/ orange B/ white + red - black If your encoder/motor is not working you can invert its direction by switching A and B position OR through the Farmbot software configuration (farmbot.io Device > Hardware).
The encoder cable colors are the following : A yellow B green A/ orange B/ white + red - black
5V Encoder power is shared thanks to 5 connector lever nuts.
