For use in the Formbot Raptor and Raptor 2, T-REX 2, 2+, 3 or other 3D printers with removable stepper drivers. We have tested these thoroughly on the X and Y axis on the Formbot machines with great results! For the Raptor, you will need at least 2 pieces (up to 4). For the T-REX, at least 3 (up to 6) NOTE: Firmware changes are needed! Hardware compatible with StepStick and Pololu A4988 Drive capability up to 1.2A (RMS) continuous coil current - 2A Peak Step/Dir interface with microstep interpolation (up to 256 microsteps) Configuration via CFG pins or UART interface Motor supply voltage: 5.5...36V Logic supply voltage: 3.3...5V Components on the bottom for better heat dissipation stealthChop2 - for quiet operation and smooth motion (default setting) spreadCycle - highly dynamic motor control chopper (enabled via UART) Authentic TMC chip assembled by MKS Recommend current Included: 1 assembled stepper driver 1 heat sink
