Replicape is a 3D printer cape for BeagleBone. Features include: - 5 stepper motors (2.5A DRV8825) (X, Y, Z, Ext1, Ext2) - 3 high power MOSFETs (PWM controlled) for 2 extruders and 1 HPB. (12..24V) - 3 medium power MOSFETs (PWM controlled) for up to 3 fans/LED strips. (12V) - 3 analog input ports for thermistors. noise-filtered inputs and option for shielding - 6 inputs for end stops (X, Y, Z). - 1 bus for Dallas 1W temperature sensor for monitoring the cold end. Many sensors can be added to ne bus. - Programmable current limits on steppers motor drivers (SMD). No need to manually adjust a pot meter. - Microstepping individually programmable for each SMD from 1 to 32. - All steppers are controlled by the Programmable Realtime Unit (PRU) for hard real time operation. - Option for stackable LCD cape (LCD3). HDMI compatible LCD on the way. - Single 12 to 24V PSU, fans are still 12V. - Comptabile with BeagleBone and BeagleBone Black. - Open source hard ware and software. - Software written in Python for maintainability and hackability.
