- Mach3 RNR USB controller using a spindle and laser, the laser is mounted with an offset to the spindle.
M3, M5 for spindle ON\OFF toggle
M4, M5 for Laser ON\OFF toggle
PWM - S0 for 0% (off) and S1000 for 100% laser power
The custom Aspire PostP work well for both, laser with offset and standard laser on offset
A wiring diagram can be downloaded from the link below.

This is very exciting as I have much the same machinery. I am working on duplicating your setup but was wondering how to modify the offset for my machine. EXCELLENT Video!
@johndavis415
Thanks for taking the time to watch my video,
I have added a G92 in the PP in aspire for when I use both the spindle and laser for a task.
I'll put the Offset PostP on the site, and check the link from time to time.
Wery well done. I will use your diagram for my machine!
Hi Kobus
If you need any other information please shout..
super thank you for knowledge!
Awesome video well done!!
Thank you very much!
A really simple way to make a stand alone laser work with Mach3/4 is to use the Z- pin as a laser on command along with a simple AND gate with the spindle PWM out pin.
S0 = 0 power and S100 =100% power.
In the CAM software you can assign a tool number and save it as Laser, you then need to set the depth of cut to minimum and plunge rate to max ( along with Z speed in Mach3).
Then you can run any spindle type program as a laser.
Buenas tardes, excelente contenido lo tendre en cuenta para la instalacion del laser. gracias
Hola Ramón, de nada. Si tiene alguna otra pregunta o idea, no dude en ponerse en contacto conmigo. Buena suerte con tu instalación.
Hi!
Thanks for the interesting content!
But did you manage to solve the problem of delaying the movement at the moments when the laser is turned on / off?
After all, when executing commands for controlling the spindle and coolant, Mach3 causes a delay in tool movement.
Thanks.
Hello David! Can you help me? I have a question. I watched you diagramm - so, M4 - it's an individual item what should connected to the board? Or it is virtual mach3 item what should be set in settings?
And another one. If laser uses 12v, I need to connect 12V of my 12v-power source to 24v on RNR controller for supply AVI and ACM?
Thank you for your video it has been of great help to me in constructing my CNC. I have now purchased a laser and am at a loss as to how to connect to 10V on the RNR board since my drives and spindle are 24v and the laser is 12 V. And I already have the 24v spindle connected to 10V, Any idea how I could connect
Get a laser driver and use the external power source on the driver for your laser and normal ttl/pwm from the code source!
Hi Dawid. Dankie vir die detail video.
Ek het 36v power supply vir steppers. 12v 30 amp power supply op die "24v" dcm circuit (limit switches, home switches En e-stop).
Ek het aparte 12v 2.5a power supply vir laser (sculpfun s9. 12v, max input 3a).
As ek jou reg verstaan, koppel ek laser power supply+ op relay input op 10v en relay output op laser+, laser power supply-en laser gnd op acm, laser pwm op avi.. Dan van dcm na relay coil, en relay coil na dcm.
So skakel die 12v circuit dan die relay aan, wat dan van die 10v circuit die laser en pwm krag gee.
Of, sal dit okay wees om die 12v 30 a power supply te gebruik om te koppel soos jou diagram... Ek is net bekommerd dat die laser 'n label het wat sê max input 3a...
Dankie vir jou bydra tot die cnc gemeenskap baie ouens probeer maar het nie 'n clue hoe om die kennis oor te dra nie. Na jou video maak baie dinge meer sin.
Hi JP
all noted noted on your setup 36v PSU for steppers - Good
12v 30a PSU is good for all you 12V devices including your Laser, The Device connected to the power supply can not use more than its required amount , So if the laser requires 12v 3A a 12v 2A psu will not be a good idea , but 12v 5A will be perfect ..so long story short 1x12V PSU is good .
For the Laser to work
---------------------------------------
12V+ PSU to 10V RnR
12V- PSU to ACM RnR
Laser - to ACM\12V-
Laser + to NO relay
Laser TTL\PWM to AVI RnR
12V+ PSU to COM relay
12V+ to Relay coil A
Output(2) RnR to Relay Coil B
Note:
The Output chosen will need to setup in the Spindle setup (CCW) =Pin2
you are welcome to whats-app me or video call ( number on website in the video description )
If you are using a Spindle that has PWM control you will need some isolation with slightly different wiring .
Good luck and keep us posted on your progress.
@@ZR6DLG legendary. Thanks David.
David, this is gold!!! There is no info like it on the internet. Well done! My laser did not come with a driver board, can I connect directly to the USB controller or do I need to find a driver board? If so, any suppliers in SA that can help me out? Could you share your ports and pin setup in another video please? or the .XML file?
Hi Nico
Thanks for the response, Regarding your laser driver it might be a little more complicated than just buying the first driver you find, I use the 40Watt NEJE laser the has a very simple external driver which has very few components, Some lasers have complex driver boards, the best advice at this point is to identify what laser you have and find more info or datasheet. hit me up with more details and I could try to help in your quest to find a compatible able driver board.
I'll gladly make a new video regarding the ports and pins I use for my setup.
I'll include the XML file on the new video

@@ZR6DLG absolutely brilliant! you should get a medal of honor for this.
Hi David, thank you for this reply. I bought a 40W (5W output) fixed focus laser off Aliexpress. I contacted Gadgitech.co.za and I can buy the 5.5W Laser driver board from them... but Im not sure if it will work with my laser. Its the closest I found to a driver board for my laser in South Africa. Any thoughts on this? One more question: did you manage to get rid of spot burns? The Bitsensor control board does not support M10/M11 commands. The M3/M5 commands causes spot burns. Apparently the answer is setting up one of the axis to switch the laser on and off, but I've not been able to get this right.
@@nix12m check the link, grab my number and we can communicate over whatsapp or a phone call, there are a few things to consider.
M11, M10 unsuccessful as well.
The axis switching is a better plan.
I have very little to no spot burning.
The drive board sold by gadget shop is a NEJE driver board it has 2 diodes, 1 tactile switch and a few connector blocks.
If it was me ill comment it using the components direct. That's me and yes i do have a few screws loese.
Hello. Thank you very much for guiding us who just started in this laser connection with a Bitsensor controller.
I have some doubts about it, since you mention the StevesFascinations channel, but it shows and recommends two power sources, both 24v and 12V, however in your diagram you only mention a single 12V source.
Also, I am using a VDF, which provides the 10V. How should I do it under this scheme? Greetings and thanks in advance
Hi
The CNC machine can run is a verify of different setups, power supply and wiring methods.
Please understand MY home brew CNC runs on only 12Volts.
Some stepper motor drivers work from 12volts to 48 volts so using a 24 psu is also ok.
Please feel free to PM me on WhatsApp or FB Messanger, i have a diagram that uses the following setup.
VFD spindle - 10v pwm
12v laser - 12v pvm
24v PSU for stepper driver
Both spindle and laser switch on and off independent both pwm working.
@@ZR6DLG Thank you very much for the answer David. I would like if you could share that diagram to see if I can connect my spindle + laser. Please give me your contact so we can communicate. Thank you.
@@HugoAlbornozC follow the link in the comments, you can find my contact number on my website..or find me on Facebook( David Le Grange..)
Nice 🙂
Thank you! Cheers!
Thanks for great video content. I have a question, why do you need a laser driver board between the mach3 board and the laser head? can we directly wire the AVI,12v and GND directly to laser head? Could you put a link to the laser driver board. I couldn't find it, and the image just too small. Thank you!
Hi Gianghuguyen84
in some cases one could connect direct to the laser, but in some other cases not, I would not recomend doing somthing im not 100% sure of.
There are many make and model lasers out there and not all of them work the same.
Note: Please use my circut diagram as a guidline
@@ZR6DLG thanks. I've been try contact you via Whatsapp but it seems my Whatsapp cannot find your contact with the phone number provided in your web. I have strange behavior with my Mach3 setup, could you give me a clue? My problem is given below G code, whenever I run in single BLK mode, it is fine.

Hi,laser head 12v 3a power requirement but your using 12v 30amps its not a problem?
Hi
The voltage is the same, power supply and device, the power supply current specification must be higher than the device requirement.
Always use good quality power supplies, cheap power supply may not output the specified voltage and\or current.
I have a 24v Laser (and 24v. power supply). It will work with this configuration? Thanks for helping!
Hi Flavio
Yes it will work the same, do you have a spindle or a router that you use as well and does it use speed control.?
@@ZR6DLG Yes, I have a router, but I don't use speed control for it. I will try to set my laser module like yours. Thanks again

Hello,
I have the sculpfun S9 laser.
Do you have a wiring for that type?
What parts do I need to have to operate the laser with MACH3?
Thank you.
Hi.
Unfortunately i do not have a wiring diagram for the sculpfun S9.
I also would not recommend checking it to a Mach3 system.
Skulpfun S9 works with a GRBL post processor.. Some GRBL functions work better than Mach3 when it comes to laser work.
@@ZR6DLG I want to combine it with my CNC tool.
@@gfimonUse laser gbrl for whatever it is you want to laser, then save your work in gcode.
Export the gcode file to mach3 when load gcode file, but change to (all files) in the upload box, it will then detect your gcode file, then click to open.
hi David Le. How to add laser button to mach3 screen? Thank you.
Hi. Check the link in the description , you can download the screen sets..
@@ZR6DLG thanks, I'm got it.
I have watched this video mutable times, read all the comments and like someone ask. how to add the 12 volts to a 24 volt system to make this work? in the video your using 12 volt only.
Nem o dono do vídeo sabe. Imagina eu?
guess not. but I got it working. But it will only let me reduce power to 50%. still working on that@@Libertario_store
@@slorolewindom5364You need a (laser driver) that allows you to connect an external power source.
@@DogSeriousyes I have laser driver connected to 12volt power supply but still will not work below 50% power being controlled through my mach3 board.
@@slorolewindom5364What's your pwm frequency set at in ports and pins spindle control? And are you using the 10volt pin port or the avi port.
Put 12volts into the 10volt pin and ground it in DCM port.
With what program do you create the g code for the laser and how do you make it work? do you change it later?
I use Aspire to do design and post-processing, and I use the standard ( Mach3 ARC) for spindle work.
I have created a post-processor (Mach3 Laser) that uses the, M4 instead of M3. And in the tool database, I have setup an endmill
With the following settings
0.075mm dia
4mm cut depth ( to allow 1 pass)
80% step over.
Spindle speed = laser intensity
10= 1%
100 =10%
500 = 50%
1000 = 100%
Feed 500mm/min depending on the Material I'm working with.
If you want me to share the PostP hit me up.
hello thanks, I'm trying to replicate because I use the same rnr and the aspire and I have it with the spindle and it works very well. the laser at the moment works with the button but the beam is not seen.
If you have wired it actually and M4 turns the laser on but no beam, I'd geuss that the laser intensity/ spindle speed is 0. Manually set speed/power (lower right side of screen) to 100 that should give a beam.. Good luck
hello david I've been going crazy with the configuration for two days watching your videos and a hundred more. turning it over and I couldn't turn on the laser light. I even thought about changing the rnr. I have the xml the screen with the buttons the post processor the laser tool. and the only thing missing is a cable to the 10v input that I did not put because I have the rnr the tb6600 powered at 24v and I missed that cable now it works perfectly thank you very much for all the help now with this configuration the motors work for me even better thank you very much Regards

hello david le grange.
i want to ask about can diode laser head be controlled via mach3 usb i tried to connect but failed
@ucmanhngo
Yes it does work,
I use Mach3 USB RnR controller
I use Aspire to generate my tool path
Mach3 does not work like a GRBL controller.
Mach3 does not work with light burn.
I have great success with my diode laser.
@@ZR6DLG so I control the diode laser through the Aspire right?
@@ucmanhngo1751
Yes that's right.
I use Aspire 9.5.
Tool i create for this is v-bit
I set cut depth to 0.2mm
As the Z axis has no need to move up and down..
Control laser power ( spindle speed)
0 rpm = 0 power
500 rpm = 50% power
1000rpm = 100% power
I do most work with 25%power
Set the spindle speed to 250rpm
When selecting the tool path.
Profile cut.
On the line
0.2 mm deep
Hope this helps..
@@ZR6DLG ok thanks
May I ask if the laser head is connected to the pmw pin of the mach3 or is it through the laser driver?
@@ucmanhngo1751
I have a NEJE lsser head that comes with a driver board.
RNR control board PWM connects to Laser driver board and driver board connects to laser head.
