Have anyone managed to get a rotary working with the U-axis on a Ruida 6445S controller? Researching it appears to be a (in)famous topic - with no real bulletproof guidance or solution… A lot of people including myself mistakenly bought the controller thinking it was the 6445G (which seemingly is …

Yup [image] mrsamdk: I can still only choose Y-axis for the rotary. Thats the only option for us folks using Ruida. The U axis is useless unless you are using it for a shuttle conveyor. I have tried many times to get this to work, with absolutely no luck.

This was a year ago, has some links from ‘them that know’… :crazy_face: [image] Rotary attachment 6445G Ruida controllers Ok guys this is my first post over here due to a problem that came up today . I am using a chinese laser with a 6445g ruida controller and today i tri…

“Yup” → As in, you have a working Rotary wired up as the U-axis? :slight_smile: Or do you simply plug-in your rotary to the Y-axis slot on the controller every time you need to use your rotary?

Thanks, it seems to be a real and disturbing struggle… :sleepy: The topic you refered to is for the G version of the controller - which sadly is an entire other thing than the S version → firmware’wise atleast

I plug mine into the Y. The machine is useless for ‘non rotary’ use with the rotary sitting in the middle of the machines workspace and it’s taller than my lenses are long. Might be nice to just plug it in, but I haven’t seen a good fix yet… :smile_cat:

There are some firmware out there that’s supposed to work… I have the 6442G, so it isn’t on the top of my list. Seems I’ve seen some using the Z axes… :smile_cat:

May I ask what your workflow is? What happens when you turn on the controller - won’t it mess with the default attempt to do a homing sequence? Really astounished that this seems to have been an on-going topic for years

The RDC6445S-V26.01.16 firmware I mention in my original post, is one of those mentioned “fixes” - but I dont see any difference at all. I also tried plugging my rotary into the Z-axis instead of U-axis, but in the rotary settings the option to pick Z-axis is disabled (greyed out)

[image] mrsamdk: turn on the controller My habit is to power up the machine and let it home, and ‘hot’ unplug the Y, with a ‘hot’ plugin of my rotary… Use it almost weekly and have about 7 months of doing it that way. It didn’t seem to make any difference when I power cycled it and had to ha…

I have 6445S and use U axis for rotary with no issues. I bought a 3rd Axis driver and installed it on the U axis, added a port into the machine to plug the Rotary into, and also added a switch to turn it on/off if not using it. All I have to do is set rotary -yes on the controller (or via LB) send…
