TTL / PWM – how does it work with the laser.

How to notice a PWM pin on your board with a multimeter.

Quite often nosotros become questions about TTL and PWM.

How does TTL works, how should it exist connected, what voltage is needed to command TTL, what to do if yous want to control the light amplification by stimulated emission of radiation intensity just you do not have a PWM on your board, etc?

Here we are going to highlight the key things about PWM & TTL.

TTL voltage

one.
Endurance lasers
support TTL+ with voltage command in the range of three.v – 24V (if you demand to operate the laser with lower voltage – let us know and we will make a custom solution for you).  It means that any voltage in this range volition activate the MOSFET and the laser will piece of work. The voltage value does non affect the light amplification by stimulated emission of radiation power – it merely affects the duration of the point. For example, TTL volition activate the light amplification by stimulated emission of radiation at whatsoever voltage in this range, at any duty ratio, without changing the laser power.

In other words, if yous have (i) three.5V output with 50% duty ratio the laser will piece of work with fifty% ability, and the same will be if you accept a (two) 24V output pin and a fifty% duty ratio but the boilerplate (if y’all will measure with a multimeter) voltage will be 1.75V for (i) one and 12V for a (two)

How to find a PWM pin on your mainboard.

2. If you do not have a separate PWM on your board and yous want to control the laser – some boards can have different voltages on power output, for example, your power output can be 0-24V, in this instance just connect the TTL wire to the 12V of your
FAN1
(sometimes
FAN2
on 3d printers) and use your existing power output to control the laser.

for concern and for a hobby!

Most Fan pins take congenital-in PWM. And it can be easily observed since fans could rotate at unlike speeds.

Mostly all CNC boards have carve up PWM pins for diode lasers.

What to do if there is no PWM pin on your controller lath

3. If you do not accept a PWM output but your board is uniform with an Arduino Nano then yous may utilize the D11 output pin as a PWM to command the TTL.

4. On nigh CNC machines a spindle output or spindle speed output can be used to control the laser power by way of irresolute the impulse duration or by irresolute the voltage on the output slot. (make certain it is not exceeding 24V)

In continuous mode, at that place is the maximum frequency and you can toggle on and off the commuter. The light amplification by stimulated emission of radiation diode can be modulated at very loftier speeds. The MOSFETs and their driver must have an upper-frequency limit.

Right now our
Mo1
works with 250-500 Hz  (laser boxes ver one.0, ane.i
)and our
Mo2 PCB
works with 25 kHz frequency (laser box ver 2.0).
