Hallo everyone!

I hope you can help me, I’m slowly running out of ideas.

I’ve upgraded my old 130w CO2 laser from a Puhan Ph3 controller to a new Ruida RDC6445S controller (complete set).
Laser power supply, motor drivers, etc., remained the same.

The conversion itself was not difficult.

Now, everything seems to work fine.
Home position, limits, and motor step size… all good.

But, I’m having major issues with the speed!

For example, if I set the controller to move right at 200mm/s, the distance and speed are correct.
It moves 200mm in exactly one second.

However, when I set the cutting speed to 100mm/s in LightBurn and try to cut a 100mm line, the machine suddenly takes 50 seconds for 100 mm!

No matter what values I input in the program, they are always too slow!
Even though the controller shows 100mm/s after loading the file, it doesn’t reach this speed. I have to set the values extremely high to come close to a normal value…

I don’t know what to do anymore…

Can you please help me?

Thank you very much!
Best regards.
