Not the answer you are waiting but there is something wrong with your shield, I have a 2015 and 2019 Shield and both are just very good even if the first one has nearly 10 years

I don't use orca, but you may have a setting to reduce retraction in infill. This is for reducing printing time. You can disable it (if there is this setting)

Hot water can also be useful in some case (not boiling hot), also help to avoid burned marked due to a flame (in particular with white filament)

Not sure I'm taking about the same thing but what I've seen is people printing a couple of layers out of pla then switching to other material to avoid having to mess with glue or else. This is to avoid bounding with plate as it can happen with petg or other material. But in no case I've seen people printing entire build area, usually the same size as print + a bit of extra to pull off that pla layer

Not sure that's a leak but couple of pictures available. Will add them later

Pla and Petg are fine but as already talked, they are other things to take in consideration. Best thing you can do is to apply a coating of food safe epoxy.

You can use a slicer feature which will pause at some specific layer, if you have a dedicated app on your phone, it will notify you that printer has been paused.

I had no idea there could be alternative firmware for the camera. Will check that. Thanks

It's either over extruding or a bed level issue. First level bed again and if it still happening calibrate your extrusion flow. Since you had adhesion issue, probably just bed leveling will solve issue. If bed is well leveled and still have adhesion issue, clean your bed with basic soap and hot water (and avoid touching bed with your hand as much as possible)

Don't know where you heard that but micro Swiss hotend has been really popular until dragon hotend came out. I'm not saying it is better than dragon but was known to work great. About prices, it might depend where you live as I just checked right now and dragon is more expensive than micro Swiss.

Oh, then I guess I didn't understand OP correctly as I understood he has a Bowden setup with his orbiter. Thanks

Don't know which printer you have but if your main interest is a direct drive setup over Bowden, chances are that you can setup your orbiter 1.5 as direct drive by printing some adapter.
