You can add a close cousin to the Web UI that FluidNC uses if you add an ESP-01S to your SKR. I’ll edit this post in a few minutes with links.
SKR pro is still a great board.
Jackpot / FluidNC does have advantages, not the least of which is that Ryan designed and supports the controller and FluidNC is in active development.
Edit: Here’s a good thread on the forum on how to add an ESP-01S to your SKR.
Maybe if enough existing SKR users ask nice, Ryan would add them back to the store so upgraders don’t need to buy and flash their own. Maybe with a reasonable markup for the time he spends flashing them.
