My controller is a little different than the 644 I ordered

[Rich]

I have a Morn 80 W MT-L960 CO2 laser/Engraver. The speed and feed are acting up and out of control. I use Lightburn. I ordered a 644 2 controller. It has arrived and it is a little different than mine. Is there someone to ask for help to see if I can use this 644 in my machine? I do have a photo of my controller and do not see a way to share that here.

Hello Rich, can you provide your order number? Let me check for you what model you bought. The posts here can share pictures directly, and you can send photos of your controllers.
