That's true. I suppose keeping track another way might offset the added annoyance of the "rewind" routine (attaching another device, connecting USB for power) when refilling the reservoirs. Personal preference I guess.

Add a tiny push button (or just two copper pads), pressing/closing which will dischage a capacitor indicating "need to rewind" to an MCU. When counter is zero, you take off the cartridge, pour in all necessary chemicals, hold the button for a while and put it back into the machine.
