K40 Laser - Latest GRBL controller board from Monport V2.0 - Lightburn compatible - See Description

Is it possible to run the potentiometer and a test fire button on the machine with Lightburn too?

Where did you get the board from now as say only usa

Why are pins 3 and 4 linked? Is that test fire to ground on your power supply?

Will the ammeter stil work with this configuation, and should the power in Lightburn be about 70% max for tube life?

My power supply has 2 wires on the second jumper the red one do i need to take the 2 wires off and make a jumper on the last 2 screws great video by the way

Hi are the links/bridges in the PSU necessary?

3 days I have been looking for something like this, a fantastic video, Thank you!!!

my k40 don't got a ribon connector... what now?

anyone else have problems with this connection?

can not tell where the link cable is pluged into

where does the CBI cable plug into on board??

I need better instructions for version 2 please. I have the digital readout and test button on machine panel.

Does anyone know the type of connector for the power input on the control board, i have the old k40 with a 6 pin power connector but only 4 slots being used

ciao io ho un laser co2 40w simile alla k40 ma con il piano di lavoro 40x40 cm e sto usando come scheda di controllo una MKS ma se devo aumentare la velocita di scrittura non mi scrive e non disegna bene in pratica non mi piace come lavora , tu pensi che questa scheda della Monport V2.0 - Lightburn compatibile , faccia la differenza enorme ,fammi sapere e ti ringrazio

I try to run lightburn but not moving and when I open console msg "ALARM:9 Homing fail. Could not find limit switch within search distance. Defined as 1.5* max_travel on search and 5* pulloff on locate phases."
But I'm sure limit switch it connected...
If any one have same problem and have the solution let me know.
Thanks

Hi
I have the same board and same power supply and did this exact installation Only thing i did different was cut the plug off the CBI and limit switch wiring Normally CLOSED and now my laser doesn't move , can you help me to run my laser?
Thanks

Can you explain the purpose of the jumper(s) you show adding the one from 3 to 4 but I see you already have one between 5 and 6. I have everything wired according to your schematic but the fan, pump switch and lights don’t turn on or the laser doesn’t home/move but I can discover the board in Lightburn. If I detach the black wire from the Laser Control cable everything turns back on. I have the “green” power supply, is it possible that I need to reverse the Red and Black from the Laser Control on the power supply?

did you have to adjust anything in the software to get the power levels working correctly. I got mine all connected now (thanks to this video) but cant seem to get any power out of it

Hi @pinger622, have you tried photo engraving with this board?

What are the main benefits for using this board besides the easy installation? I see that it has a 32-bit CPU vs the 8-Bit of the M2 Nano but does that really change raster performance that much? Is that the only advantage?

Good morning, I have a cnc co2 80w, PSU ZYE MYJG80R and PSU 24V. Can you tell me if it's compatible for me to replace the m2 nano board with this monprt?

The video helped configure the new board into the laser, Monport even sent me your diagram to help me , I wonder if you can help me with the air assist, i fitted a lead into the air assist socket but i don't know what voltage is coming out I entered M8 into the console and put a meter on to test the voltage but it showed nothing. I assumed it would be the same as my other lasers and output 5V DC to power a relay. Can you advise me, Monport say its 110 V.

I just put this board in my k40 and between cuts if i don't home it each time it doesn't line up on the "Y" it'll be off by 1-2mm did you have this issue at all? I have a video I uploaded on my channel showing it

Hi Pingers i installed this board yesterday and cannot figure out how to now do a test fire to align mirrors. How did you manage this?

Do you have wiring steps for that controller and the type 1 power supply? BTW, excellent detailed video!

I have the same board and same power supply and did this exact installation and now my laser doesn't move at all and if I unplug it from the computer it's immediately fires the laser like the test fire would do. No idea what to do now 😞

I just dont understand how they launch the 2.0v with better hardware but way less features than the 1.0v (ex: 2.0V doesnt have Z height, doesnt suport rotary axis..)

Hi, I have the board connected and it works fine, but I can't figure out how to connect the air assist, the output to air assist, it doesn't make any changes when working with lightburn. Greetings

Pleased I found this as ordered board yesterday and have the same PSU as you and had concerns over the PMW cable, thanks for making this! Having used the board is it ok? And do you have any still shots of the PMW connection to psu please.

Hi. Try this. Unplug all usb devices (except keyboard and mouse) from your computer. Turn the k40 laser on. Plug the usb c cable into the monport board. Make sure your computer sound is turned up. Plug the other end of the usb c cable into your computer and listen for the 2 tone sound (usb device detected). Start lightburn and go through the find laser process. If it still does not detect your board then check that there is power reaching your monport board. Hope this helps.

I got the 2.0 board 3 week ago but my did not work. Light burn did not read the new board. When I go through to find my laser no laser was detected. I have write to Monport about it. This what they told me ( please remove all sockets except the socket of usb so as to have a try and ur motherboard can access computer without cable as well. ) don’t really know what the mean by that if you please help
