Duet3d Control Board for Laser Engraver K40

uneumann36

Hello my friends

So, i got a new hobby, yes i buy a Laser Engraver Model K40.
I search in this Forum for Information, but i found different information´s but not really understandable for me.
Because this programming stuff is not my favorite.

In the past i build my own 2 3D printers with Duet Hardware.
So i understand this hardware now, and i like Duet Hardware and support! You all are very good.

I already updated and upgraded my K40 with different things.
So i add the mini gerbil on this printer use Lightburn and so on.
It make a lot of fun to work with the K40.
And important! My wife is happy to about the results. ( Happy wife happy life)

So my Question is, is it possible to use an Duet Board instead of the original Board or the Mini Gerbil Board???
Because the connection and possibility’s of Duet Boards are much better and i like Duet.
I need to know if there is a good working solution to use a Duet or what kind of Duet?

Hopefully i get some feedback from you.

Regards
Uwe

Does anyone know if this is possible?

Hi @uneumann36, yet it's possible. If you search this forum for K40 you will find some other users. Duet 2 boards needed a gate such as 74HC02 to interface safely to a laser, but Duet 3 and 3 Mini boards have a laser/VFD output with 5V signal levels built in.

Hey DC
Thank you for your reply.
No Problem for me to buy a Duet3 Board.
I already have one for my 3D Printer, and i am happy with it!

The reason why i want to use a Duet Board is i am totally happy with Duet , the Forum, and your great Support. Also the possibilitys of Duet Boards are very good.

So is a manual how to use a board for K40 and or how to set it?

Cheers

Here, but it's more like a puzzle.
This one is the basic guide

@uneumann36 we have a K40 user created config here https://github.com/TeamGloomy/LPC-STM32-RRFUserConfigs/tree/master/K40 CO2 Laser - SKR 2 - ESP - paulg4h

@o_lampe
Verry good, Thank you.
But in the manual i found they use a Bigtreetech SKR 2 board with ESP8266 WiFi Module
Not a duet board!
Or is this board the same?

@uneumann36 it would also work with a duet board.
The firmware is the same
