Before I updated the firmware on my Sculpfun S30 Pro Max I was able to use current position without getting an alarm error.
Now anytime I use the option I get this error.
Any ideas on what may have changed?
Something unseen in your project can send the engrave head out of range.
In the workspace in LightBurn type Ctrl-A then Ctrl-Shift-A.
This is a Select all - Zoom all approach.
Click the Preview button in the top row in LightBurn.
Switch on Show Traversal Moves toward the bottom edge of the Preview window.
Capture that screen image and share it here. It may show us why. 
Your origin is set to center. That’s problematic usually. Set it to bottom-left to have the correct starting point.
Another reason can be that the firmware upgrade reset the workspace size set in the firmware. What’s the output of the $$-commad in the console window?
Here is a reference table for the firmware settings (table at the end): Firmware Update & Settings - Diode Laser Wiki

Fixed the issue by flashing FLUIDNC to my Scupfun S30 Pro Max, the firmware it comes with is garbage… (I say this becuase I flash FluidNC, did NO config other than Melvins .yaml and everything is working like out of the box but with better features like Wifi, who uses bluetooth?)
I can now use current position without any alarms, and without homing on startup.
Before this I HAD to have homing on startup enabled. Otherwise I would get that error pictured above, now all is well.
Thank you for all the help!!
Basically, it’s just a different approach in both firmwares. It depends which position they set after boot time. As long as you have limit switches, it’s advisable to do a homing cycle at the beginning also with FluidNC. Otherwise, the coordinate system is not set correctly and you might crash into the rails. While using FluidNC, if you don’t home, but the laser is positioned at the center in the beginning, the laser will still think it’s positioned at bottom-left. So, just be aware.
