    Hello,

    We have seen this several times and think that it comes from having small time gaps in your gradient method, for example:

    0.00  10%

    1.00  10%

    1.05  90%

    The gap of 0.05seconds and the jump from 10 - 90% seems too much for the pumps to cope with. We found that if you increase the step time to 0.1 or 0.2 then these problems go away.

    To have proper step gradient you could use curve type 1 or 11.
