Best way to switch cartridges mid print

Hello all! I am fairly new to the form 4 ecosystem and am having a minor issue. Everytime i have to switch cartridges i get a minor line defect at the point where the resin was swapped. I am beginning to make some tools in batches of 10 tools (650ml). I have 1 Liter cartridges that i will have to change every print unless i start with a new cartridge and dont use the leftover which isnt ideal.

My first thought was to get a pump and 5L bottles but id have the same issue just less often.

Is there and settings that might help reduce this?

don’t leave it paused for more than a minute and that shouldn’t happen if it’s going to be overnight, make sure you have enough to start it tells you how much resin it’s going to take to print and if it says you have less than that then either put a new cannister in or manually add resin to the tank but dont over fill

That makes sense for some situations but i was hoping there was something more seamless so i can print unattended.

I assume if i dump a partial cartridge into the vat the system can read that resin level? That way it uses the resin i added before using more of the cartridge.
