Delta Calibration Help

I am trying to adjust the steps per unit parameters in order to calibrate my printer, hoping it will print a little more accurate. I was following this tutorial that seems to be for Cartesian style printers (I know they both technically work in the Cartesian coordinate system) but I assume the commands are different for a delta style printer. When I follow the steps in the link below, my printer does really weird and undesirable things so I think its different for delta printers. Is it?Steps I am trying to Follow:https://all3dp.com/2/how-to-calibrat...ply-explained/Printing a 25mm x 25mm x25mm block, I'm getting about .4mm precision, which sounds terrible to me. Also, I'm getting this weird wave/ripple on the corners of the print.

Circled in yellow.
