I’m hoping someone can help me here. The issue is that I don’t understand anything about electricity, but I can follow pictures and diagrams.
I needed to purchase a new laser tube for my K40, and I decided not to upgrade to a 50W tube. Therefore, I bought a new 50W tube and a 50W power supply from Cloudray. Before ordering, I contacted Cloudray customer support to inquire whether my machine with the Nano2 motherboard would be compatible with this type of upgrade. I was informed that it would be compatible.
When the new parts arrived, everything was fine until it was time to start the electronics. The new power supply had fewer connections than the old one. After conducting some research online, I discovered that I needed an additional 24V power supply. I also found a picture of a diagram that appeared very similar to my situation.
After completing the necessary adjustments, the machine turned on and connected to my PC. The third mirror moved with the 40k whisperer controls, but the laser itself did not turn on. Neither switch was working, the LED ammeter was showing nothing, and the potentiometer was not functioning.
Is there a way to fix this issue with my current setup, or do I need to purchase a new motherboard?
the voltage between the G and P is ~4,66V
the voltage between G and IN is ~4,66V
With the pot turned all the way counterclockwise, I got ~0V.
As I turn the pot clockwise, the voltage gradually increases until ~4,66V
And still no laser action.
I am just verifying that the meter and our measurements are correct by measuring a known point.
--------------------- Reasoning ---------
If there is no 5V on the LPS [i.e. measured .4v], then the LPS supply is bad.
However, this is a new supply and that would be unusual.
In addition, the light on the LPS is on. That LED is connected to the 5V side of the LPS. Why is it on yet there is no 5V on the output pin?
Trying to make sure something is not fooling us into believing the LPS is bad.
Important: Make sure that nothing is connected to the 5V or any other output pin when you measure it.
