I have tried for over a hour to update my Ruida to the RDC6445G-V15.01.22-LIB.upd so I can utilize my U axis.
I just installed a U axis driver and from the control panel, RDWorks and Lightburn all 3 moves the rotary.
Tried 2 versions of RDWorks. Keeps saying wrong version.
Currently have RDLC-V15.01.19 in the machine.
Any other way to upload this firmware?
.30 is the latest firmware out. I always update firmware via RDWorks, never had a problem.
Does it still support the ability to use the U axis?
Ok I finally loaded it. Turns out it was a corrupt file.
Now to continue setting up this rotary.
U axis is working!
