Thank you for sharing! I still have to get the laser out of the basement to the garage where the CNC is located. I just bought a metal lathe so that took priority right now. Canada is wonderful in the summer so lots of out door activities. Winter is cold so that is when most of my electronics/programming/cnc work is done. I will give your ideas a try when "I get around to it"!

@@stevesfascinations1516 I tried many Post processes from other 3rd parties outlets, keeping in mind there are other types of break-out boards that are not compatible with the RNR, none the less Have fun while the sun is out, if you run into a snag regarding the post-processor please feel free to give me shout, I'm happy to share, I also have my wiring diagram also available. 🍻

Hola, no estoy seguro de lo que quieres decir. Hay muchas fotos de la PCB en línea y cómo conectarla.

Life got out of control for me, so I have not had time to complete the install. There are wiring diagrams in the video. They are pretty straightforward connections.

Hi Washington, thanks for the kind words! I will be using vectric aspire for the designs and I found a post processor for laser that I will likely use. I am going to use an external relay to turn the laser power on/off, and the PWM signal to control the intensity (mach3 will think it is the spindle speed). I am trying to find time to tear down the CNC control box so I can add the connections for the laser and finally install the laser on the machine. Hopefully I will get to it this weekend and I will make a video of the process. I will make up a diagram showing the relays etc to help others out :-) Too many toys, not enough time!

Thanks for the reply. I'm glad you can help other people. The visualization of the electrical connections makes it much easier to understand. Good luck to you and God bless you!

Gracias por mirar, me alegro de que ayudó con su construcción. No estoy seguro de lo que quieres decir con la salida. Creo que es una salida PWM que controla la intensidad del LÁSER.

Hi Massimiliano Gilli, thanks for watching the video! I am pretty new to lasers. I have experimented with laser diodes with various power levels. I have made PWM controllers and power supplies for them. I was not aware that the freq is supposed to be 1KHz - thanks for letting me know! The PWM allows you to vary the power to the laser by chopping the DC power into pulses. If you increase the voltage you will get more power out of the diode. The diode is rated to 12VDC so that is what I used. I did not think it would be a problem for the control card and I was correct, it works fine.

@@stevesfascinations1516 My point is that Pulses are between 0 and VCC (either 12V or 24V) and not really related to PWM voltage. The PWM can be either TTL (5V) or 12V and what matters is the duty cycle. But i guess we are on the same page. What about the breakout board is it good?

Hi KatMan Dude, thanks for watching the video! Some things look easy (and are) some things look easy (and are not!). It sounds easy to grab a bunch of items, interconnect and away you go....the lack of documentation makes this difficult and time consuming. I am going to attempt to use vectric aspire. It will need a new postprocessor for laser use. When I get around to hooking it up to the CNC I will create a video to document the process. I like making these videos as it refreshes my memory. Sometimes when I do not do or use something for a while, I kinda forget how it was done....these videos are helpful to remind me!

Hi Martin Matjasic, the laser needs 12V, I am not familiar with the CNC Shield, but if it puts out 3.3V, you may want to use that voltage to trigger a FET to switch the 12VDC to the laser.

Hello, Did you find how to wire the S9 laser? What parts do you use to work it? Do you have a wiring diagram? Thank you.

Sounds like a defective laser or you are changing the pwm over time. I believe the spindle speed can modify the intensity, check to make sure your code does not change the spindle speed in the area that is causing you trouble.

Ok, I did the calibration and can now adjust intensity. But still not able to use M11 command.

@@nix12m I would think the intensity would be with M3. Wikipedia: The speed of the spindle is determined by the address S, in either revolutions per minute (G97 mode; default) or surface feet per minute or [surface] meters per minute (G96 mode [CSS] under either G20 or G21). The right-hand rule can be used to determine which direction is clockwise and which direction is counter-clockwise. I have a dozen projects on the go so can not help much right now.

@@nix12m This board do not support those commands.

Hi Dillon Dopp, thanks for watching the video! Yes, I am connecting the +12VDC to the 10VDC input on the card and the S9 Laser +12VDC Input together. The grounds are also connected together (ACM on the board, and GND on the 12V power supply). The AVI on the board goes to the PWM pin on the S9 connector. I hope this helps clarify things! If not, let me know and I will try to help further.

Hi gfimon, thanks for watching! The video was about the Sculpfun S9 laser module, and there is wiring info in the video. I am using a USB->Stepper/motor control board and the info is in the video. It is pretty straightforward, if you are stuck on a particular issue let me know.

@@stevesfascinations1516 I'm stuck at the wiring it self. Can I contact you by other way than here?

Hola Jose! Thank you for watching the video. Turning it on is easy, controlling the power is the tricky part. To turn on, simply connect the VCC (Positive DC Power) to the PWM (Pulse Width Modulation) pins together and then power them both up. It will then be ON at 100%. You can do this either with a relay or a switch. I hope this helps?

Hi Bensaad, I am not sure what you mean, at 2:26 there is a wiring diagram. Is there something that you are unsure of that you need clarification? There are only three wires to the laser, only two wires on the 12VDC supply...

Hi Gary, that is a little vague, what are you having trouble with?

@@stevesfascinations1516 Post processor setup and ports and pins , do u have Messanger we can text from

Do u have a wiring diagram that shows all connections

@@garyparrett8955 Yes! Look at 2:25 there is a diagram in the video.

Thanks for watching! I do not have any experience with C02 laser (I wish I did). If it has a PWM input you can probably wire it similar to what I have done with the LED laser module. Sorry I can not help more!

Thanks for watching! I have a stand alone laser I use light burn with. I am not sure if lightburn is compatible with this setup or not. I suspect it will not work with the USBCNC

Hi Adem, what do you need help with?

@@stevesfascinations1516 I'm using the same card, I want to install a laser module, but I couldn't make the electrical connection, can you help me?

Thank you for watching the video. I am certainly available.
