Pretty sure that's correct. I went the Marco way because I thought this was a dead project.
Quoted from RobF:For those curious, this is what the kit looks like at the moment (minus some screws). I have an idea on how I want to mount the PCB, so probably one more printed part to design.

This is super cool man. What a way finish off MET pro.
Some good news on progress! I was inspired to tackle one of my remaining two issues; the PCB mounting. The difficulty was that two of the connectors from the harness that my control board needs (the plug to the inline target opto board and the cross LED) come from different areas of the harness. They are only just long enough to meet in one common area for my board to live. Think of it like a minimally overlapping venn diagram. I thought about cutting zip ties and rerouting parts of the harness or building my own extension harnesses. Neither of which I was very keen on. I also was trying to minimize the amount of mounting hardware and wanted to avoid putting more holes into the playfield. I am proud to say that I figured out a way achieve all of my design goals and came up with a clever place that this thing can live.
In the end, I designed three new 3d printed parts that attaches the PCB to the backside of the cross magnet mount. I am quite proud of this one

The hex cavity fits over the magnet core jam nut leaving the threads of the core exposed.

The knob wheel screws down on the exposed thread from the magnet core and locks it into place.
This looks pretty turnkey and user friendly. Please put me on your list if there is a list. Very snazzy mounting solution.

Expensive, but cool to have if your MET Pro is a keeper.
Can it be added to a pro and work correctly without premium code?
Quoted from adam12hicks:Can it be added to a pro and work correctly without premium code?
That would be the reason for this thread. The short answer is yes, but since there is no code to directly activate it an alternate method is needed (like using the target opto and cross LED to trigger it).

I'd just buy this when RobF sells them. Unless you have the Total Light Show or are very handy with figuring out how to trigger the up and down motion I'd wait.
For me, I have the TLS and couldn't wait. LOL.

Ah gotcha. Ok awesome! Mine doesn’t have TLS but has some LED interface board that makes them behave like incandescents. Removes the flicker and fades them up and down. Not sure where that board came from but it does work well.

Is it the LED OCD? http://ledocd.com/cart/index.php?main_page=product_info&cPath=1&products_id=2
I get the feeling Rob is making a bunch of these without telling anyone. Then when he is ready to sell them they are ready to ship. I imagine there are a bunch of people messaging him. I think this is the coolest mod and definitely cant wait to order one.

Ha. No, I am not making a bunch of these behind the scenes. I did however add a new 3d printer to my print farm in anticipation of the demand (which brings the grand total up to 2 functioning machines 
). I do expect there to be quite a few folks wanting to add this to their pros.
One piece of sour news to report is that while looking at ordering more parts to build my first handful of kits, I found that 2 (out of 3 total!) parts I need for my controller board are all victim of the Covid parts disruption and are on extended backorder. I have a crummy back-up plan that might allow me to still build a few before the end of the year, but that is to be seen.
I still have some code improvements to work on to eliminate the rare false cross raisings. The good news is I am taking a decent chunk of time off from my day job next month. Fingers crossed that I can wrap that all up then.
I appreciate all the kind words and the enthusiasm.

If I can help in anyway with this, Please let me know. If you would like me to pre-order, I can do that also.

Quoted from snakesnsparklers:My poor cross has been stuck without movement for 84 years now, can't wait for this mod!
Huh?

Quoted from bicyclenut:Any progress? I really would like this mod for my MET. I hope things are going good
Yes there has been! I will start to have these available around the new year.
I rewrote the control code and finally solved my last false triggering bug that would cause the cross to go up at the end of the ball about 10% of the time. As I mentioned, I am running into the chip shortage. The micro controller that I use is backorded until Jan'23! My workaround right now is to cannibalize arduino boards and use those parts. The cost is higher and it does take time to depop, but there isn't really any other alternatives. Who knows how long the arduinos will still be available, but for now I have enough parts to make a few of these.

Put me first in line as a “beta tester”

First in line? I think not

Awesome. Thanks for the update.
I don't think I'll need any beta testing after all. I am not keeping any lists. When the time comes, I'll make it clear how to put in your order and fill them as they come in.

I was only joking

yeah no worries, just keeping things clear
