Introduction: Neje DK 8 Laser Engraver on Windows 8 - 10
I received my Neje DK 8 Laser engraving machine (my machine has a USB > Serial cable direct connected).
In all communication they say that you need Window 7 to run this thing. I am on Windows 10 and tried to load the necessary PL2303_Prolific drives, even new ones from the internet without any luck.
When I looked at the backside I noticed that they use a Arduino Mini, direct connected to the USB > serial cable.
Step 1: Using a FTDI Interface
On my other Arduino projects I use a FTDI interface which you can buy for around 2$ on the Chines web-stores.
There come in different layout but in basic they all the same (USB > TTL), take the 5 volt version.
Now remove the cable from the Machine Arduino board.
Step 2: Connect the FTDI Interface to the Machine Arduino Board
Now connect the FTDI interface board to the machine Arduino board.
Please note the Layout of the machine Arduino board (picture) and connect it to the FTDI interface;
Machine > FTDI
GND > GND
Vcc > Vcc
Rx > Tx
Tx > Rx
Now connect the interface to your computer and select the right Com port.
Mount the FTDI interface with double sided tape or by your own solution.
Step 3: The Software I Use
I use the "Mini Larser" software, latest from their website or supplied with the machine.
We have a be nice policy.
Please be positive and constructive.
