Good to hear that you are up and running!

Setting $10=4 should not impact the information that UGS receives from GRBL, only the information reported when you send a '?' command to it. That said, it would probably be helpful to check if your system is seeing any machine/work positions using this method. Set your $10=3 (or 7) and send it a '?...

The only thing I can see in there that UGS/GRBL won't like much is the T1M6 command, as tool changing is not supported. Some of the older versions of UGS tolerated this and some of the newer ones throw an error. Maybe try (commenting the line with brackets) and see if that helps. My version complain...

That is a peculiar issue. I would suggest that opening an issue on the UGS github page is the best way forward. Will is usually pretty good at getting onto things there.
You really aren't having much luck with this are you?

I would guess that it needs calibrating and the travel resolution settings need updating. ($100 $101 $102) There are some good details on how to calibrate it on the wiki, or you can just use trial and error.

Yes, I did build my own probe. It's fairly simple if you have access to a lathe.

In which case you could always bump up the search rate ($25) higher if you are unhappy with the current speed. It feels like a long time when you are just waiting on it, but in real-world use you tend to be doing something else when the machine is homing. I tend to set my machine to 'home' while I s...

The difference will be in repeatability and build quality. Both will function the same way, although I doubt that the cheaper one has a nice spring in it. The spring is important to save the tip of your sharp tools; although many people have success with their un-sprung versions. I find I run my too...

I would adjust your Homing Search and Homing Locate speeds.

$24=25
$25=1000

This will allow it to search fast, then slowly confirm the position of your homing switches afterwards. You can speed it up more, but it can overshoot - which is not good...

The X & Y directions should not matter in terms of which hits first. My machine will home successfully with either of the directions hitting first. You may find it difficult to simulate the hit/pull off movement with just your manual shorting of the wires, but it sounds like things are working as an...
