Electronics
A device uses electronic components similar to ordinary RepRap. Namely, four stepper motors NEMA 17 (holding torque at least 44 N cm); Arduino Mega 2560 controller and expansion card RAMPS 1.4; four stepper motor drivers A4988; three mechanical limit switches; Smart LCD Controller with a four-line LCD screen, controls (angular sensor and buttons), SD card reader, shield cable to connect to RAMPS 1.4; PSU 12 volt 20 amp.
Special Considerations
On the stepper driver board the jumpers need to be installed under each stepper driver to full step.
