How do I go about determining a suitable max acceleration for my retrofitted z18 running klipper? Is it just "make it move the print head across the bed with increasing acceleration until I hear it start skipping steps and then dial it back"? Similarly, how do I determine how high to set run current? Right now I have the xy steppers at 0.7 amps, the z stepper at 9.75, and the extruder (voron printhead) at 0.3.
