I bought a TS6090 80W laser cutter made with brandname "JIN ZHI YIN". As you would expect with a cheap china laser cutter the controlling hardware (and software) is a bit crappy. I make the changes as mentioned here so I can use this lasercutter for my own makerspace

TS6090

Specifications (in short)

  • Bed size 60x90 cm
  • 80 Watt laser tube
  • Flow sensor (connected to power supply)
  • Lihuiyu M2 Nano controller (with Coreldraw plugin and USB protection)

Controller board of TS6090, Lihuiyu M2 Nano

So I want to upgrade the 'brains' of the machine with a MKS board (clone of smoothieboard). TkkrLab have already modified another lasercutter that works well with all the modifications, so I want to change this laser to the same software.

Hardware Modifycations

Needed parts

Prices are indication of cost, no shipping, tax etc.

Small electronic parts

  • For power controller
    • 2 Optocouplers $0.50 a piece and
    • 2 x 100R
    • 2 x 500R
    • 6 female pin header for the power controller
  • 2 x JST 2 pin for the endstops

Additional general info

Changes

  • XY Stops was 1 connector (white bottom on before photo), changed this to two separate JST 2 pin connectors. Use a multimeter to see how the connections are.
  • Power for the board, we only need 24V. Smoothieboard has screw terminal, just screw on the cables (was 24+5 volt for Lihuiyu board)
  • Smoothie use the same connectors for XY steppers, so just plug in.
  • Added switch between water sensor to disable laser when door open. The pin is labeled with "WP" (Water Protect).
Added open door switch sensor to the WP pin

Laser control

Power control was done manually with a seperate control (bottom left on before photo, that has to be done from smoothieboard. For this we create a small print inspired on our experience with the TkkrLab lasercutter.

Remove the original analog display (unscrew bolts) and button interface (you can control it by software, so not REALLY needed). Later you can replace this with a nice LCD display & Rotary Encoder. The connector of this original analog display is connected to laser controller and smoothieboard J8 (near SD card).


Camera

I use Lightburn for controlling the laser, this has a camera option.

  • 8MP camera with viewing angle of 85°, bought via Aliexpress and USB extension cord.
  • Camera mount via thingiverse.

12864 LCD Display

This part is not working yet, so use at own risk!!

This is only the bare display, so without 'smart' features like SD card or included rotary encoder.

Pin layout for MKS Smoothie and 12864 LCD Display. Mentioned colors is what I personally used, so they have no special meaning.

Software

First update the current firmware with the latest. All left to do is to make a good 'config' text file with all the settings. Download here my config and firmware
