Let’s take it a bit slower and take a look at what you have connected and what’s actually working. If you can provide a picture of your setup, that may be helpful. The one above is from a seller’s website, has wires all over the place and doesn’t even have a laser diode. I am assuming you have one.

MPCNC – This would be your machine as a whole.
Is this working in any capacity right now? If so, what does it do?

Laser Diode – This should have 2 wires, a red one and a black one.
What and where are these connected to?
When you say everything is working except for the RAMPS, does this mean you’re able to activate the laser manually?

Laser Driver – This should have 4 2-pin connectors.
Are the connectors on your board identified?
What is connected to any of the connectors on this board?

Fan – This should have 2 wires, a red one and a black one.
What and where are these connected to?

Laser Power Supply
Are you using a separate power supply for your laser than you are using for your RAMPS board?
How many Volts and AMPs is it rated at?
What is it connected to?
What is the voltage reading from your connections?

LCD
Are you using one?
If so, is this successfully controlling any of the other electronics on your MPCNC?
If not, how are you controlling the fan speed and any of the other electronics on your MPCNC?

Ramps and Arduino Mega – This refers to the 2 board combo stacked on top of each other.
Besides the RAMPS/Arduino Mega combo, what pins/connectors are connected to what connections of your laser diode, laser driver, fan and power supply?
