Did you manage to get accurate dosing? at minute im counting steps to 100ml as a calibration then doing
calibration steps / 100 * how many ML to dose
Just wondered how accurate you found these dose heads and if you ever got to try the BPT tube (thicker wall)

Yup! It all depends on the pump head - the smaller chinese stepper heads don't like the thicker wall tubing and aren't very good for dealing with higher vacuum (long intake pipes).
If your feed and dispensing tubing and setup is the same, once calibrated its very consistent, much more so than the DC pump motors.
