Pulse generator selection
Pulse engine supports different pulse generators:
- Integrated pulse generator (for up to 3 stepper motors with step frequencies up to 25 kHz)
- External pulse generator without dedicated IO capabilities (for up to 8 stepper motors with
step frequencies up to 125 kHz) using PoExtensionOC16 or third-party custom board.
- External pulse generator with dedicated IO capabilities (for up to 8 stepper motors with step
frequencies up to 125 kHz, dedicated limit+, limit-, home/ref, axis error inputs, 3 relay
outputs, 4 open-collector outputs, 0-10 V output) using PoKeysCNCaddon (pictured below).
PoKeysCNCaddon inputs and outputs are galvanically isolated from PoKeys board.
