Thanks this gives me confidence to embark on fitting a laser to my CNC. Love your very tidy wiring, I am the same.

Hi Stephen...thanks for the information. I assembled my CNC controller but for the 5v and the 12v , I used an old computer power supply. I have used it this way for over a year with no problems and I bought 5 computers to $20.00 so they are cheap.

That should work fine.

Stephen, I am in the process of adding a laser to my CNC using Vectric Cut2D and Mach3. Your video has been very helpful in this process and I really appreciate it. I am only able to get the laser to fire for a spit second using the #16 pin with my Mach3 settings as you have them. My trouble seems to be with the Post Processor. Would you be willing to share the PP that you use?

can you share wiring diagram? of your laser to mach3

@shaunwhiteley3544 7 жыл бұрын

That's great, thanks, so that works great for vectors but did you get it to work with raster images, photos? New subscriber

@WassellWoodworking 7 жыл бұрын

Great question. I have not experimented with raster images. If I do, I will post it.

Hi Stephen, nice video and thanks for sharing. If using a relay to switch the laser (TTL I assume) on and off, how long will the relay last?

@WassellWoodworking 7 жыл бұрын

I don't know ho long it will last. If the relay stops I will post a video. It has been through thousands of on/off cycles so far if not tens of thousands.

I wonder if you could help me? I bought a 10 watt laser and I'm having a problem turning it on and off. I'm electrically challenged. I'm not to clear about connecting a relay. I have a 5V relay with a 5V power supply. My router is 48V, and the laser is 12V. Do I need a 12V relay? Any help would be greatly appreciated.

Dan - Not sure if I am going to be able to help you too much. The relay should be a 5v relay. The NO, NC, and Common connection are separate from the coil portion of the relay and are usually rated for up to 230v. I used a 5v relay board that I purchased from Amazon or eBay. The PC uses 5v to run the breakout board that in turn controls the relay board with the same 5v logic. I used the direction of the z setting to turn on and off the relay. I think it is in the video. Hope some of this helps.

no dice cant get it to work. using mach 3 mkx lv controller and shoot me please like now. Im jumping! laser stays constant. Question hard wire into a axis z axis or output port 7????????????

@WassellWoodworking 6 жыл бұрын

Sorry about the delay. The relay should be triggered by the direction of the signal. When want the relay fed by the direction signal. Down for on and off for up. Hope that helps. Did you get it to work? If not let me know. - Steve

Thank you for the video. Question: Why does the A drive need to be configured?

@WassellWoodworking 7 жыл бұрын

I was probably talking about the 4th motor which is sometimes called the 'A Motor' or 'A Drive'. This is not to be confused with the A disk drive. Thanks for watching.

@johnhorne3862 7 жыл бұрын

I was referring to the A motor not a disk drive. Since the z axis is not used why does it have to be configured?

@WassellWoodworking 7 жыл бұрын

OK. I understand the question. The z-axis is used to trigger the laser on and off. I set the Z depth to -0.01". When Mach3 (CNC software) sends the breakout board the command to move down, the voltage for direction triggers a relay. When the Z axis goes to +0.01" the voltage comes off and the relay shuts down the laser. Basically I am using the direction on the breakout board to run the laser relay. I have the A-axis to raise and lower only before the laser is triggered to get it to the focal height above the work piece. I hope that helps.

This clears everything up. Thank you for responding.

@bricedrilling1299 7 жыл бұрын

just something i noticed. the steps are not the same on the Z and A axis. Z = 1600, A = 2000.

I will take a look. Thanks for pointing that out.

Randy - It is a SunFounder 2 Channel DC 5V Relay Module. Here is the link on Amazon: www.amazon.com/SunFounder-Channel-Optocoupler-Expansion-Raspberry/dp/B00E0NTPP4/ref=sr_1_2?ie=UTF8&qid=1492042646&sr=8-2&keywords=2+relay+arduino Hope that helps. Let me know if you need anything else. -Steve
