base? emitter? collector = gnd, resistor 1k ohm, base 1k om resistor -PWM from 57cnc, emiter to L fire laser? did i get it right?

If I understood correctly PWM turns on the laser only a small amount of time to get a percentage of the power.
And the pot still determines the max output power. Which means that I need to connect to a PWM contact shooting laser.


It is important to keep the Pulse Repetition Frequency below ...

Hi:

   You dont need to use step motor 8 for connection to anything, the stepmotor 8 display shows motion
during shooting only because that channel is used as the pwm control word internally for the pwm channel
real time control you use to trigger the laser. You can use any of the 4 pwm ...

sorry i was busy. if i understood correctly i need to pokeys57cnc connect laser trigger to step pulse motor 8. and PWM4 to pin18 pokeys57. i have another question whether step laser ignition should be inverted or not. if need be if the software or do I need hardware-inverted signal.

Greeting
here a beginner with auggie software.
need help how to connect pokeys 57cnc with k40 power supply? I mean wires. i am using auggie version 3.7 which communicates with pokeys 57cnc.
