Hello, can you show how you wired it ?
Thx
Thank you, Sir.
Hey NorthernStrong, so did you get everything working with this? Iâm getting ready to try this board out.
Thanks, G
Hi there
Yes. It is running.
BUT the wiring has been changed.
The TTL connection for the DLC32 V2.x is different to the V1.1
I could not use the GND from the TTL (top right corner).
I had to use the GND from the âSpindleâ.
And all worked out.
IMPORTANT
Turn off the laser when powering up the unit.
There is a split second that the laser is firing.
Beside that, I am using with my digital panel to set the âMAXâ current.
Cheers.

Thatâs good news you are up and running, Iâm just getting ready to try mine, I will switch the âGâ to the spindle, Thanks for the heads up on that, anything else I should look for? Thanks and happy burning.
That does look like a nice plug-and-play boardâŚ
For me it is an easy upgrade.
I did remove my photo sensors and replaced them with the mechanicals ones.
I had to figure out the directions and how the HOMEming sequences were.
NO for the sensors.
Wi-Fi LIVE streaming to engrave from Lb to K40 is not working well due to the latency.
But you could air drop using and lunching the web UI from your PC web browser ( you need micro SD installed on the board) the Gcodes generated by LB and run it locally from the main board itself.
If files are saved on as card, and you needed to cut/engrave days/ month after, you just need to select the files from the touch screen and play it. No need to open your PC/ laptop.
Good luck!!
Thank you, SirâŚ
Hello NorthernStrong,
I was wondering if there is any way you could share your GRBL settings?. Iâm having a hell of a time with it, I get it works with the control board and then doesnât work right with Lightburn, then I get it working with lightburn and it doesnât work with the control board. any help would be appreciated.
Thanks for your time and help
Yup. To set up the Grbl was a heck of challenge.
Spent 3 days to figure it all out.
I have posted in the FB K40 laser enhancement group already.
I am trying for about 5â now and
LB forum doesnât allow me to post .nc files
Will try with pc tomorrow.
I connected:
- Spindleâs Gnd to L
- TTLâs S to IN ( you need a two way switch so the Controllerâs IN and TYLâs IN are not conflicting)
The IN can only take one signal; either from the digital controller board or from MKSâ TTL S.
-24 V Dedicated power supplyâs Gnd to laser power supplyâs Gnd

Just add .txt on the end as a file extension and try again - I want to see success and I want people to get to their goals.

UPDATED WIRING CONNECTION
due to the MKS DLC32 V2.x has significant trace changes, it does not work wiring the TTLâs Gnd to the L of K40 power supply.
I am wiring it from the Spindleâs Gnd to the L. this is tested on my K40 and it is working well.
pls see the updated wiring diagram.

What I do is add the .txt, so if itâs whatever.pdf â whatever.pdf.txt
That identifies the original formatâŚ

Hi Bob, I will give this a try and let you know. Thank you for taking the time to help me with this Sir.
Never mind on this Q 
Well Bob, Iâm bummed to say this Didnât work for me. My brain is fried for today, if I have time I will mess with it more tomorrow. Thanks for your help.
If you post some picture of your wiring and set ups it would be helpful to allow ppl around to help you better.
I use LaserGrbl to connect to my board first and load the config to the board.
I find this is easier for me, rather using a microSD card to load or from LB.
I did replace my OEM limit switches to mechanical one and routed new stepper motor wiring.
I am using a dedicated 24 V dc power supply to run the main board and stepper motors.
A dedicated 5V dc power supply for sensors lcd.
Good morning Sir, Iâm at work so canât post pics, This laser is a omtech K40 newer model the mini version.
I have a dedicated 24 V power supply to run board and steppers, it has mechanical limit switches, with your setup it wants to home lower right, my limit switches are upper left, but I can add two more if needed, as for the jogging âX-Yâthat works in LB , but not for touchscreen the Y axis moves in wrong direction.
On MKS Discord, one guy said I needed to flash the board FW (grbl) with the direction I wonât my steepers then change it in lightburn, because they are two different setupâs, not sure how to do that because if I change anything in LB it will change how the touchscreen works. Thanks for your time and help.
