HI Friends......
I am absolutely new in this field so i am a complete novice.......
But I would be highly obliged if i can receive some info regarding CNC Laser Engraver on the problem that i am currently facing.....so i will get straight to the point........
So, i bought an EleksMaker Laser Engraver of 500mW and 450nm wavelength(BLUE) non-adjustable.......but the thing i didn't notice while buying it was that it had neither PWM nor TTL modulation board to which i felt there might be less performance without either of it........
So my question are:
1) What is the use of PWM / TTL modulation in the Laser Engraver? Will it be fine without it ? Or can i add some TTL board to it ?
2) What is the use of Relay Module as i have seen in many videos in YouTube ?
3) What is the use of End Stop module in the Device or Why is End Stop used in it ?
4) Why is Jumper Connector Caps used in all the 3 Pin Slots for each axis(X, Y & Z)?
