Can you use a smaller flexplate?

Hello,

As the printer only does the first layer height calibration in  the area that you are printing, can you use a much smaller flexplate (for example one of the size of the MK3/4) to print on? Did somebody already try it? I'm curious whether it is possible or not. Thanks!

RE: Can you use a smaller flexplate?

I've tried this with an unused build sheet sized for a CR-10S and it works just fine.  You just need to be absolutely sure the printer won't try to bed level outside of the plate (I used it with very conservatively small models so there was no chance of that).  I can see Prusa not "supporting" or recommending this but there's nothing the printer does now that prevents it from working.

 I guess  there could be some heating behavior that's less efficient as the firmware assumes there will be some steel plate where there is none...

RE:

@darksharpie brings up a great point. Even when slicing objects that fit entirely on the front left heat plate, if I use extruders 3-4 it will still move to the right side of the plate to mesh level because the purge happens on the tab on the right side. So you are probably risking quite a bit by using a smaller plate. At best it will just throw an error because of the height difference. At worst I can see it hitting the edge of the plate as it moves over to level. And it moves very quickly. I don't know that the load cell will trigger and the printer will stop before it knocks your nozzle crooked or something.

Hello,

Now that I've received my XL, it seems really obvious that it isn't a good idea to try using a smaller flexplate. Thanks for your answers!
