I was running my shapeoko 5 for a few hours making a pocket. It messed up so i stopped and initialize the machine. It makes an odd sound when homing. It never sees the X axis home and fails initialization. I can put a piece of metal next to it and the light turns on.
When you re-initialize, can you tell if the z homing is being triggered?
I’ve accidentally plunged and lost steps on the z before which ended with the z carriage trying to go higher than expected.
This resulted in the z just sort of jittering when I re-initialized and because the z homes first, it might be bailing out before it even attempts the x/y homing sequences 
I can check but it retracted fine. Then y is good. Just cant get far enough right to home the x
Is the leadscrew okay? All the hardware on it in place?

Do you know if you can move the X axis (machine down-powered) any further closer to it associated limit switch? Or is it physically at its stop?
Try down powering the machine, slowly move the X axis to its midpoint then do the same for the Y axis. Power up and reinitialize and see what it goes.
I had those events not just once. The light on the sensor itself reacts, but the according light on the controller board does not, check that out. Sometimes even a light of another sensor on the board reacts: long story short: might be the contoller board. There are just some bad batches out. CC service guys react fast and without further ado.
I was able to move the machine manually into the space so the sensor could read. The last inch did require a lot more force.
I did some maintenance and added lube to the guide rail berings.it seems to be bertter now and i can home the machine. Im going to run another project and see howbit does.

If this is the case then you need to perform maintenance on the entire machine.
Glad you got it to home finally.
