I have Ruida RDC6445S controller. It does not respond to the Air Assist switch enabled in LightBurn.
Nothing suggested in this forum for controller RDC6445G works for me. I suspect there are some incompatibilities in RDC6445G and RDC6445S firmware and as result LightBurn does not add correct configuration to the cut file.
The solenoid is working as expected when connected to the 24v power source directly.
Firmware version I have in my RDC6445S is RDC6445S-V26.01.19
I have the following voltages on the controller Cn1 pins.
Funny enough, but I figured out what was the issue. For some reason I expected the LightBurn will do the work for me to enable all required config params in my controller after I turn on the Air Switch in LightBurn but this is not the case.
For those who come here with the same issue here is my solution. See screenshots for details.
Go to the Manufactory Settings. Default password is RD8888.
Go to Machine Config and make sure that the “If blowing” param is set to “Yes”
After I did that the WIND pin turns into “Ground” if air assist for the layer is on and as a result the solenoid opens the air flow as expected.
