I have done a few searches in the forums, but can't seem to find a solution for this. Most likely because I don't know yet what to search for

I have run the delta calibration wizard, adjusted the eprom parameters and fiddled with the obvious things, yet my first layer is always squished flat, and depending on print speed I get extruder-skipping due to this. Can anyone point me in the next direction? Should I fiddle with the z-probe distance manually?
Halp!
