I don’t think too many people know this but the terminal console that comes with Windows 10/11, Mac OS & Linux can be used to SSH into Klipper hosts.
Here’s my Windows 11 system:
No need to install PuTTY except if you’re doing file transfers to the host but I’m not sure how much of that is required for Klipper - You will want to download your printer.cfg and klippy.log but that can be done from the Mainsail interface.
