Is there a Firmware version for my 6445G(EC) that will allow LB to select any Rotary axis other than Y?

getting the U-axis (or A-axis) to be selectable in LB

Does the Enable U Axis switch in Device Settings have any effect?

There are several controls available in RDWorks that LightBurn doesn’t provide, but the Ruida doc varies between misleading and nonexistent. Previous discussions have hints, although typically for Z vs. U axis operation:

Using the U axis for rotary control on a KT332N

After reading this post Ruida 6445G controller and rotary attachment problems - LightBurn Hardware Compatibility / Ruida controllers - LightBurn Software Forum, I got to wondering if it might be possible to co-op the U axis output on my KT332N controller for rotary use. On my last CO2 laser (an MF1220-50) I had to resort to a 4PDT toggle switch because the RDC6442 didn’t support U axis for rotary, though I read that the RDC6445G might. I now have an OMTECH ZF2028-60 with a KT332N and I wonder if…

Z axis not homing

Back onto my DIY laser build after a few years off, Have the x/y axis homing fine, however the Z axis does not even attempt to home. I have it enabled in lightburn, and I can manually move it from the ruida control panel. Initially I designed it to have the bed move for Z adjustment, but have added a custom motorized laser mount that will function as Z, and will setup the bed to run off U Axis. Does this have to be enabled using rdworks first? I originally was just going to use rdworks, but…

Trouble getting Z-axis limit switches to operate

Hello, I’m trying to get a friends machine to work properly. My machine and his are identical–Lightburn DSP, Ruida 6445 controller. The Z-table goes up and down, but the limit switches at the top and bottom will not work. When the limit switches are tripped manually, the correct lights on the controller cpu flash correctly, but they will not stop the travel of the Z-table. Any thoughts would be welcome. Thanks, Mark
