Ruida 6445SS – Rotary Not Moving, Y-Axis Partially Active
Hello everyone,
I’m having a strange issue with my Ruida 6445SS controller and my rotary attachment. The rotary was working before, but now it’s completely unresponsive. Here’s what’s happening:
Issue Description:
- The rotary is recognized in both LightBurn and RDWorks, but it does not move.
- The Y-axis is restricted (it only allows fine adjustments) instead of being fully disabled when the rotary is enabled.
- The laser receives the rotary settings, but when I start a job, it does not rotate—sometimes the Y-axis moves instead.
Troubleshooting Done:
Checked and reconnected all cables (multiple times).
Enabled and disabled the rotary setting in both RDWorks and LightBurn.
Reset the controller to factory settings and reloaded the settings.
Rewrote the rotary parameters (including pulse settings).
Tried different Circle Pulse values** (5000, 10000, etc.).
Unplugged and reconnected the rotary multiple times (also tested after a full power cycle).
Y-axis moves normally when the rotary is disabled.
The rotary used to work before – no hardware changes.
Additional Info:
- Controller: Ruida 6445SS
- Software: LightBurn & RDWorks (both tested)
- The rotary is connected via a single cable, replacing the Y-axis (no extra U-axis available).
- I tried sending movement commands, but the rotary remains still while the Y-axis is partially responsive.
Does anyone have an idea what could be causing this? Could this be a firmware issue, or is there a setting that might force the controller to fully switch to rotary mode?
Any help would be greatly appreciated!
