Why is Send G-Code disabled in 2.3.0+
Hi, sorry if this has been answered many times before but I simply can't find it. I must be doing something wrong.
PrusaSlicer can send firmware updates to my Mk3S+ over USB, but Send G-Code is grayed out on the File Menu -- why?
I have my printer selected, and I can sneaker-net files using an SD card, but why can't I send directly over the USB cable?
I'm getting a Pi Zero W, so I hope to solve this soon with Octoprint, but I am still wondering why this obvious functionality is not working. There appears to be no way to tell it to send over USB, but only using a hostname/ip address/octo or other protocol.
Thanks for any help!

On the Mac version, the File menu does not have a Send gcode option. I believe the ability to print directly from PrusaSlicer was removed some time ago. In general, printing from a general-purpose computer is not recommended due to the tendency for operating systems to run automated updates, screen savers, and power-saving features that can interfere with a print. Most prints take some hours to complete. A flash firmware update, by contrast, only takes a few minutes.

Well I installed OctoPrint on my Mac, following the directions over at OctoPrint.org, and I can print from the browser over USB, and generally control the printer -- great!
I still can't get PrusaSlicer to see the printer; tried host = localhost:5000 and a few other things. Anyway, I guess this will work for now; no more sneakernet!

Hmm. I wouldn't install OctoPrint on the Mac. Ideally, you want a computer that isn't' subject to shutdowns, sleep, and updates. A Raspberry Pi is the most common approach.
Did you try just "localhost" for the Host IP? Your Mac firewall might be interfering. Be sure you've copied the API key from OctoPrint into the PrusaSlicer setup.

Or just the IP address (make sure it's static in your router). Ditto re. installing Octoprint on PC/Mac.

Pasting in the app key did the trick; thanks for the tip.
Now I can print directly from the slicer.
Meanwhile, my Pi Zero W just arrived, but it needs the I/O attachment. Or maybe I should just repurpose a Pi 3 that I have lying around?

@terry-8
I would use the pi3. Even though the official prusa instructions use the Pi zero those are way out of date and the official developer of octoprint states that the zero is not recommended. Basically if you use the prusa image designed for the zero you will be using a very old version that you cant realistically update and you also cant put extras on as the zero wont handle it.
With the 3 at least you get a more capable board.
