Occupational experience as a machinist/toolmaker/electronic technician on precision CNC machine tools and control retrofits.
Just purchased a 13 year old Blue/White Redsail M3050 50W laser about 6 months ago for dirt cheap. After getting it home and proving it did in fact work as is, it made more sense to retrofit than buy the dongle for the vintage software on the old Leetro control.
Ran the gamut of research and decided on the Ruida RDC6445G. Very nice control features and HMI bang for the buck.
Then, I just found out while attempting to configure the rotary axis as the final piece of the project.... it is not a true 4 axis controller as expected. The brochures and manual skipped over this detail entirely.
The only hint what the 4th output "U axel" was for was a feeding parameter and little else. I have since discovered it is more or less a conveyor feed. Not the rotary 4th axis I had installed a drive, power supply and wired up for.
A couple days ago in my frenzied research to resolve for my issue, I did run across a modified version of firmware RDC6445G-V15.01.22-LIB.upd which redirects the Y axis pulses to the U axis output. I could not find any cheering supporting that as the holy grail solution or much discussion proving its worth. Which is why I find myself here. I do have emails out to Cloudray and Ruida for the firmware version RDC-v15.01.19 and HMI-V10.01.09 before I even try installing the rotary patched version. Still awaiting a response there. As far as I know, there is no option to extract the existing firmware for backup.
Please cut/snip/transfer this to a more appropriate area if preferred. Feedback and guidance much appreciated!
