Yes. You should try the beta ones. In fact one of the admins of MeerK40t has two machines. He is however running these now as raspberry pi zero boards running the lhyserver. And is not controlling them over TCP. But, the latest beta have much improved two machine control. The places to run the job, let you select the machine the job should be sent to. And the devices can be easily switched and monitored.
Also, you can more easily run profiles if needed and start two different copies of Meerk40t with non-overlapping save settings -P <number> which is a great fallback method. I’m thinking the TCP->rPI method might be one of the best. But, just running two connected devices registered in the device manager is pretty effective after the devices upgrade.
