How can I access a device connected to a WiFi (not guest) network from my wired network?

I have an R8000P router. I have a 3D printer running Octoprint, which connects to my router vi WiFi. I have been accessing Octoprint via a laptop that also connects via WiFi. Now I am adding a workstation which I want to connect long-term via the wired network. However, when I do that, the workstation cannot access the Octoprint. It can't even ping that address. However, when I connect the workstation via the same WiFi net instead of using the ethernet cable, it can connect to Octoprint just fine. That's all well and good, but ultimately, I'd like to connect my workstation to my network via a cable. Is there some setting in my router that will allow devices on the Wired network to access other devices that are connected to one of the WiFi networks? Note: I'm not talking about the Guest network here - I don't use that.
