Thanks for the help Jack!
I found the Ruida manual also here and it’s true what you say about the limiters, but now I have another doubt about the ORGX, ORGY and ORGZ, because the Leetro has these extra for the Origin I suppose, but then where do I put them on the Ruida, because it doesn’t have a slot for Origin. Unless I overlap with one of the Limiters and put it at the LmtX- lets say for each of the axes. (see below the red lines)
But then I’ll have 3 wires on a pin then. As currently there are 2 yellow wires at ELX- and a blue at ORGX.
Another thing I noticed is the Laser wire connections. (Pink ones in my drawing)
Seems that the LAS goes to the LPWM1 on the Ruida.
But then what is the DA for? I don’t think is the water pomp. On the Leetro manual is market as Analog Output, whatever that means.
As for the firmware settings, where can I find them to save from the Leetro? And what format is the file? Do I connect somehow via usb to the controller or they are stored in the Laser Cut 5.3 software files on PC?
I see I have a second usb that goes on the side of the laser machine. But not sure for what is it, probably to upload files for cutting directly on the machine without PC.
