Your explanation of the PWM control setup for Mach3 is very helpful. Thank you.

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 Carlos. I am just planning out adding Laser to my CNC. This tutorial was very helpful.

Great content. Subscribed 🤙🏻

Thanks so much from vietnam.

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.

gracias,. saludos desde Brasil

parabens pela explicação e continue com esse de trabalho de sabedoria e conhecimento, fique com deus, e muito sucesso no seu canal

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)?

Bonjour Carlos, Thank you for a super video. I have learned a lot today as I'm getting into laser with my CNC. I also love your Mach3 Screen set for the laser instead of the spindle view. I wondered if you could share this screen set with us. Best Regards,

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..

Hello Carlos, how you choose which output to run, spindle or laser at the beginning both being connected? You disconnect the spindle?

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

I would love to buy or if possible get your screen set for the mach 3 laser

Thanks. I hooked my laser to relay...and controled it by signal from z axis. This is much nicer.

Carlos su video es muy muy bueno debería de explicar en español nos servirá mucho hay muy poca información como la que usted nos ofrece

You did a great job on the information, but I lost it when you saved the file to the PP folder. I saved as and put the .pp on the end but it was still saved a text doc with the txt extention on it and vetric will not see it.

where can I get a copy of the screen set that u are using . Looks great. Great video thanks

Bom dia, ótimo vídeo, parabéns pelas explicações. Gostei da tela do mach3 para laser, vc permitiria eu usá-la em minha máquina?

How can I change my screen set for laser, or can I get your's, I would be nice

Boa tarde novamente, eu nao achai o link na descricao do video para as telas do mach3 laser. Você conseguiria enviar?

Hello, I have configured Mach3 identically to yours, but I have no PWM signal on the output, what could be wrong? I have an oscilloscope hooked up and there is no waveform

Me podrías explicar como conectar el láser a la placa por favor utilizo la placa por usb roja Gracias de antemano

Amigo como puedo descargar o conseguir mach3 como tú lo tienes para láser de diodo

Buenos dias, soy nuevo y x lo que dedusco es lo que estoy buscando, pero el problema que entre el traductor y subtitulado no puedo entender nada, podras indicarme una version en castellano?.saludos

Hola carlos yo uso un relevador para el laser y lo activo con M4 y desactivo con M5, solo que lo modifico directo en bloc de notas reemplazando z-1 por m5 y z0 por m4. te muesto unas lineas. N200G00X-118.218Y54.811M5 N210G1X-118.218Y54.811M4F600.0 N220G1X-118.218Y54.913M4F1524.0 N230G1X-119.001Y55.891M4 N240G1X-119.782Y56.850M4 Pero tengo problemas con el grabado.

HOLA, EXCELENTE VIDEO. Como puedo descargar el Mach 3 así como se ve el tuyo con el logotipo de laser .....? Estoy intentando generar el PWM desde una tarjeta NVEN, pero no logro generar la salida. No sé si es mi software o una mala configuración seguí tu video, pero no logro obtener una salida.

Alguien puede decirme como Controlar laser co2 con tarjeta mach3

looking for help .would be happy to pay for the assistance

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. I'm hopping you might be able to help me resolve this problem. 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

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 for your viduo..and you can send to me mach3 for laser?

can i ask for postprocessor
