Hi All,

I have purchase a 3018 CNC engraver off eBay, but having difficulty getting either the laser or drill to turn on. The X,Y & Z axes move fine but I can't burn or engrave.

Below are the following steps tried:

I have 2 CNC 3018 machine which are different makes and one of which functions fine using the same computer & software installed.

- Taken the laser from problem device and plugged into known good machine which doesn't work
- Taken known good laser from working machine and plugged into problem machine which doesn't work
- Taken drill from problem device and connected to know good machine which works fine
- Taken drill from known good machine and plugged into problem one and it doesn't work
- From software LiteFire( v1.25.82.2040) when I click "laser on (Strong)" I see an LED turn on from the board but the laser itself doesn't turn on
- grblControl (v0.8.4) when I press the "spindle off / on" button nothing happens
- I'm confident all the wires are connected in the correct place
