How do I use Delta Correction?
Hi, so I'm trying to use the DELTA_RADIUS_CORRECTION and DELTA_DIAGONAL_CORRECTION variables in order to correct build errors in my printer and improve the calibration. However, I'm not really sure if I'm using these variables correctly. I haven't been able to find any instructions out there on how to use these variables.
Here's the issue with my printer: When printing a calibration object, such as this one: http://www.thingiverse.com/thing:745523
the lengths of the legs on the print are incorrect. When calibrated correctly, each pair of parallel legs on the snowflake should measure 120 mm on each side. Instead I get lengths like 119.53 (across tower A) 120.95 (across tower and 120.11 (across tower C). The instructions are written for the Marlin firmware, and the author has no interest in providing a Repetier version.
I know I'm not the only one with this problem, but I just cannot find a clear explanation. All the printer guides I find don't address this part of calibration.
