I need a little help with my Delta. I have calibrated the XYZ endstops, Diagonal Rod length, Horizontal Rod Radius, Alpha A/B/C and the Corr. Diagonal A/B/C. Currently the printer prints with the correct dimensions. It will print the Delta Calibration object from Thingiverse with the angles and dimensions exactly correct. The extruder tip moves flat between the center and a point in front of each tower.
However... The extruder tip rises off the build plate between the towers. The further from the center the higher off the build plate. This causes poor bed adhesion for larger prints. How do I correct for this?
