Do you have a link to a video of your implementation?

AFAIK, there are only two possible solutions: 1. The plate stays put and you knock the finished print off, or it falls off; and, 2. The print with plate still attached gets ejected and a new plate slotted in.
Well, I suppose one could possibly count a third option, which isnāt technically a continuous print cycle, but I can see how it may have some advantages: you get a printer with a huge xy build volume, and you print just like normal, except you duplicate a single print object and print a bunch of them on the giant build plate. Speaking only for myself, I kinda like this approach, because itās the simplest and leverages tried and true regular hardware. Just think how many you could, in theory, print per build plate on something truly huge like an orangestorm giga or, to a lesser degree, a comgrow t500. Or maybe the Bambu XL, but no one can due dily that option until it at least gets announced. 
Well, actually 4 options: you go old school. If you have the space, take the cost of any of the first 3 options, and buy that amount of inexpensive printers and run them in parallel. Now youāre thinking, because total print time goes down. Who cares if it sits there on the print bed while it waits for you to pick it off. It doesnāt matter, because unless youāre on vacation or out of town, your productivity may still come out ahead. Of course, it all depends on the exact print and your particular circumstances, so YMMV. But if you have a ton of parts you need to crank, and the sooner the better, this might be the option thatās very hard to beat. Itās also arguably the most reliable, because each print is independent of the other, so print failures donāt spread or cascade and force a total shut-down.
As for me, after writing the above, I changed my mind and settled on what is essentially option 4, for the reasons given.
Here is my code:
-It is pasted and replaced in bambulab in the final g code section
-I really see changing the bed as an overdue solution so as not to have to intervene.
-In my code, on the 4th line where it says G04 S1500, here we select the seconds we want to wait before removing the piece. 1500 means waiting 1500 seconds, 25 minutes.
-important to select the textured pei bed in bambulab
-In this way the printer prints continuously until we decide to cancel it.

And how do you merge multiple plates in 1 plate in bambu studio?
You can use this app. However it works only with GCODE. Means no AMS support and no remote start for files. But it does what itās supposed to.
And if I need AMS Support? What can I do?
There are ways to do this. For example by exporting a 3MF file which will act as container and then replacing the gcode file inside. I can explain in detail, but first get familiar with the āsimpleā gcode-splicer app which I have linked above.
And here is an alternative approach by using this octoprint plugin:
Seams like itās still in development but can be already used. This approach is way more comfortable than splicing multiple files into one.
Yes, I used the gcode-splicer app that you created and works but is not what I need.
I need to merge several bambu studio plates into the same so they can print separately.
Sorry, unfortunately I donāt understand what you mean. Can you please explain on some use-case?
Print several objects with auto-ejection and to be compatible with AMS.
I have the auto-ejection gcode at the end but I donāt know how to print sequently each object.
Hi, I have sent you a friend request on Discord and also am an avid Fusion user. Would love to view and collaborate on your wiper project. I travel for work a good deal and having a solution to clear failed prints or complete prints from the bed would be an absolute boon. username on Discord is Martiniman31
Hi folks, just in case someone find it usable, here is my clearing code for A1.
This pushed parts using the X-Axis (and then with the extruder). Works on some PLA parts. I would not recommend rely on it while printing in PETGā¦ at least not without proper testing.
Please note
G0 Z-18 ā here you might set the high where the X axis should push your object. Z-18 is the livest level and hit the object at high of appr. Z12. So for instance if you want hit your object at Z120 your need to use G0 Z90 here.

hello I tried your code on my a1 mini. It worked but it damaged the bed so I wonder if the code is different between the a1 and the a1 mini thank you
oh, itās totally different. Sorry for your bed. 
I wish you have had asked beforehand.
