Manipulate Cartridge Chip

This feature exists. Once you start a print and the volume of the part is higher than what the printer think is left in the cartridge, it will be throwing you a warning (something like “there may not be enough resin left to finish the print”). You can always override/ignore this warning and continue printing, at which point the printer will continue to try to dispense resin from the cartridge. I often do that and try to launch prints several hours before I leave work, so that I can switch the cartridge mid-print to a full cartridge to ensure the printer doesn’t run out of resin in the middle of the night/week-end.

As for reprograming the cartridge chip there used to be a contraption built by the community but I don’t know if it works with the last versions of the firmware :
