Delta printers. x/y correction
Hi!
Recently I´ve a delta printer with no Z probe
I have no problem with z height and flatness calibration. At first I make it manually and after I've used escher system with good results
However after printing this http://www.thingiverse.com/thing:745523, A tower size is 0.3-0.4 mm smaller than the others
I've changed DELTA_DIAGONAL_CORRECTION_A by up to -2.
This way A tower print is closer to the target value but B and C tower dimensions are as well incresed so the the difference between towers remain the same!! 0.3-0.4mm....
On the other hand this change affects to flatness. So after this, I changed DELTA_RADIUS_CORRECTION_A and made another print. In this case even the difference in size was a little bigger
Is this normal? Is this the right way for x/y calibration
Many thanks
Iñaki
