I've got a printrboard with Marlin too so I'm going to try some autocalibrate (the G30A command that probes to iteratively solve the geometry rather than the G29 that just maps the bed) action over the weekend and see where that gets me, still not convinced calibration is the issue though as the parabolic motion only seems to happen when actually printing. Maybe the PSU is getting overloaded when the bed and hot end kick in or something and so steps are getting skipped.
Can anyone answer my original question: what is the effect of missed steps on a delta robot?
More when I have some better data, thanks for the suggestions folks.
Cheers,
Robin.
