delta firmware

feste

I have a self-built delta printer. I generated the firmware, leveled the printer, but I get proportional errors. If I print a cube I have a smaller z and instead x and y of about 101%. For the z with the steps for mm I can solve, but in x and y I also have differences between them and I do not know how to correct.

First make z work as that is the real ratio you need for everything.

xy error is a result of wrong horizontal radius. This often happens when you level bed that you change horizontal radius and diagonal to fit. But that can lead to wrong geometries with even bed since you did not measure that error during calibration. Try reducing them both with same ratio, e.g. reduce both 1% so they keep the z level mostly but fix the geometry in xy.
