Two newer printers won't connect to the pi

I have two newer printers, both marlin based. One is a Eryone ER:20. I’ve tried to do a report from the Pi, but no idea if it submitted. When I connect that to one of my Pi’s the Pi interface from 3dprinterOS see’s it, but gives me errors connecting. The newest printer a Biqu BX isn’t even seen by the Pi. I’ve verified the ports connect via laptop. I’d like to be able to get this into my network of machines controlled by 3dprinter OS. The one thing I’ve not tried is using the new beta client, I’m still using the “stable” builds on the Pi’s
