Thank you Carlos for this excellent explanation of PWM, Mach3 config and how to set up for laser. You were very clear. I did stumble for about 4 hours with getting the .txt file to convert to .pp. I finally figured out you have to save the modified J tech file as a .txt then rename it to a .pp file. Thank you again for posting this.
Thanks for your explanation on how to set up PWM on Mach3. I am still struggling to get mine to actually create pulses though. I have a scope hooked up to pin 1 just as you did, but only have 5 volts solid on this pin regardless of what I try. I have disconnected my breakout board and am watching straight out of the parallel port. Has to be some simple setup I am missing. I even tried a clean install of Mach3 and only configured pin 1 as an output, no joy. I will get it, I am a Pitbull when faced with problems to solve.
I am sure you checked, port 1, pin 1 and active low on ports and pins config, output#2 enabled, and on the spindle control, uncheck enable spindle relay, and use output #2 for both CW and CCW, and check PWM control check box. PWM base frequency 250 pulses/sec. Make sure you refer your parallel port pin to gnd. it should work. Set your scope timing fast enough to read it. Good luck. Thanks for the comment.
@@CarlosMDominguez I will double and triple check everything but I think I have all that. Plus I'm going to try on a another computer in case I've got issues. Thanks for your reply.
Success!! After a fresh load of Version R3.043.062 and completing the configuration, I now have pulses! Turns out that I was missing one crucial step in testing, set Spindle speed to somethng other than 100% during test......Duh! Thanks again for your videos.
Hi Carlos, thank you for this excellent video. Could you please clarify why you mentioned two outputs but seeing the circuit you are only using 1 output (pin 1), Is really necessary the other output (pin 14)?
Good morning, thanks for the helpful video, i have a mach3 machine and i've correctly installed pwm laser, but for G-code creation i use Fusion 360 and i cant find any post processor right for my purpose..
There is a lot o videos out there about Fusion 360 Mach3 post processors. th-cam.com/video/YKsRyH6zNNU/w-d-xo.htmlsi=Y2I0GT5xc4oXeYBv This one may help. Thanks for the comment.
Hello, you can leave the wires connected to the outputs and change which one runs with the software, you can watch my video: "How to make Mach3 buttons to illuminate" th-cam.com/video/LlWTQpa9MZY/w-d-xo.html for an example of this.
I purchased a simple laser module that came with a power supply. I connected it up to AC and it will burn a line if manually moved slowly. I do not see any other connection points like your laser has. Could I use my simple laser setup and modify things in mach 3 and have it vary the power like yours does, or would I need a laser like yours to be able to control it? Thanks Hager
Your laser module has to be capable of taking PWM signals, so you can control it with Mach 3; otherwise you can only turn it on/off full power with a relay. However I don't know which module you have, I may be wrong.
Sure, try these links. one is for the mach3 set, the other one is for the jpg (picture of the background) they are on my shared folders on google drive.

Go to MDI screen and type M3 or M4 to see if it turns it on, M5 to turn it off. make sure spindle relays are enabled and that you selected port one, and an output signal # 1 and that is enabled with the port and pin number that you are going to use on relay control (make sure that output is the same), and that motor control PWM and spindle are checked. finally that you are probing the right pin on your breakout board ( make sure the scope is properly set also) Hope it works.

Thank You Carlos great video, I got My Laser installed I used the PostProcessor from J-Tech. i've used the same setting you did on the postprocessor. I'm just having one issue.

Once the M3 is activated to turn on the laser the Spindle delays approxamitly 3 seconds to start moving. it always leaves a burned dot at start of every section. any form of advice would be truelly appreciated. thank you
Try setting spindle relay delay to zero delay. go to config, ports and pins, spindle setup, see if general parameters are set to 3 seconds, if they are set it to zero. You can also disable spindle relay and use PWM control using an output signal, as I did on the video. Good luck.
Thank you for your response. I check the spindle relay delay it was at zero. I will try disabling the spindle relay delay this weekend, I'll let you know how it works.
welcome Beautiful and wonderful work I want help from you. I designed a CNC machine using Mach3, but I need a program that deals with personal photos and engraving them on wood like the laser shown. And also through Luspendal Glass, thank you
Thanks. The program I use is Vectric Aspire. Is good to engrave vector images, but not very good at raster photo images. Not using mach3 anyway. Its better to buy a K40 CO2 laser engraver for that. Or perhaps an ORTUR laser diode. Good luck.
