I noticed I get this error when aspirating 150ul, then dispensing 75ul twice in a row with the same pipette:
await lh.pick_up_tips(tips_0[0:2]) await lh.aspirate(reag_plt[0:2], *2) await lh.dispense(sample_plt[0:2], *2) await lh.dispense(sample_plt[0:2], *2)
TooLittleLiquidError: Container has too little liquid: 75uL > 0uL
However, aspirating 150ul then dispensing 150ul will work fine.
@rickwierenga do you know what’s going on here? I believe the volume tracker is used to monitor the volume of liquid within a pipette tip, but I can’t figure out exactly what we need to change to make sure the logic works properly on serial dispense.
