Configuration Wizard Question - Delta Printer Geometry
Hi I have a question
In the configuration wizard for setting up a Delta printer firmware. You have a text box for setting (or adjusting if you supply a configuration.h file) the Diagonal Rod Length (DELTA_DIAGONAL_ROD) , Maximum Horizontal Radius (DELTA_MAX_RADIUS) and Horizontal radius when centered (ROD_RADIUS) but no entry for (PRINTER_RADIUS) and the wizard will set it for the same value as the ROD_RADIUS.
It works like that but once you add corrections I found that the geometry gets skewed (for example if you offset the X position of EXT0 it has the same effect as changing your end-stops with an originally leveled bed, one side will now appear high and the other low). If I change the value for PRINTER_RADIUS manually in my configuration.h file to the the measured value, correction now works properly.
Am I misunderstanding something or was this by design (I would love elaboration) ?
BTW this has all be great fun and I have learned a lot about the inner workings of a Delta printer. I like challenges. I appreciate you taking the time to answer all of my questions.
