Available in 2 and 4 axis versions

Pin Description:

LimitX/LimitX are inputs. High = switch active

Step_x/Step_y are the step inputs. Min 1us pulse width. 1000 steps per inch of travel.

Dir_x/Dir_y are the direction inputs.

RELAY: PWM laser power control. If high, laser is on. If low, laser is off. Setup as PWM spindle in Mach3. S1000 for 1000% power. Set S10 for 1% power.

Enable: if low then stepper motors enabled. If high, stepper motors disabled. Default is high.

GND: Reference ground

Warning: It is not recommended to run the laser with the PC parallel port interface alone unless you are an advanced user. The laser will operate normally when under Mach3 control but the PC Paralle port boots up in an unknown state. The laser MUST be off before starting Mach3 or the laser input could be triggered by the PC.

Recommended connection is with a Warp9td.com SmoothStepper Board (www.warp9td.com) or a Full Spectrum Engineering USB Propeller Control board (coming soon). These connections ensure the laser will not turn on unexpectedly when booting the computer.
