Describe the bug
With a 2045 step/ml for the pump with a flowrate of 5 mL/min, when you pass 10 mL, the pump effectively pass 10 mL.
But, it takes around 3 minutes, when it should be 2 minutes. So the real flowrate is around 3.5 mL/min.
(I did this on ten units).
To Reproduce
Steps to reproduce the behavior:
OPTIC CONFIGURATION
Pass 10 mL with a flowrate of 5 mL/min. Measure the time. It should be 2 minutes if the real flowrate is 5 mL/min. But it is not the case.
Expected behavior
If you enter a flowrate, it should be the real flowrate.

However, I'd like to have the software provide reasonable defaults for the calibration parameters. Those default parameters are specific to each version of the PlanktoScope hardware. Which version of the PlanktoScope hardware are you using? My pump stepper motor calibration of 2045 steps/mL was obtained on a PlanktoScope with v2.6.1 hardware.

The flowrate is not the real flowrate
The flowrate has an incorrect calibration
Nov 23, 2023
Update: I just realized that I misread your description, so I misunderstood the problem you were reporting. If I understand correctly now, you actually do have a correct calibration for the pump_steps_per_ml setting, since the pump will pump exactly 10 mL of fluid when you tell it to pump 10 mL of fluid. Instead, it seems that there is some other setting which will need to be calibrated in order to calibrate the pump flowrate. In other words, calibrating the pump's volumes is not sufficient to calibrate the pump's flowrates.
