Bl-mach-v1.1 D302 Jun 2026

Physical limit switches, emergency stop buttons (E-Stops), and tool-setting probes run along the structural frame of a CNC machine, where they pick up high amounts of electromagnetic interference (EMI) from spindle motors and cooling pumps. To prevent destructive voltage spikes from traveling back into the PC motherboard, every input line on the BL-MACH-V1.1 passes through (frequently referred to as "light lotus root" isolation in structural documentation). Signals are converted into light pulses internally, entirely severing the direct electrical connection between external field wiring and the PC. Interface Connections and Pin Mapping

: Map your hardware E-Stop string to Pin 10, configuring it as "Active Low" if utilizing a standard normally-closed safety loop. Map individual limit switches sequentially across Pins 11, 12, and 13. Bl-mach-v1.1 D302
