I found this in the Configuration_adv.h:
// Babystepping enables the user to control the axis in tiny amounts, independently from the normal printing process // it can e.g. be used to change z-positions in the print startup phase in real-time // does not respect endstops! #define BABYSTEPPING #if ENABLED(BABYSTEPPING) // #define BABYSTEP_XY //not only z, but also XY in the menu. more clutter, more functions //not implemented for deltabots! #define BABYSTEP_INVERT_Z false //true for inverse movements in Z #define BABYSTEP_MULTIPLICATOR 1 //faster movements #endif
It puts a babystep z in your LCD “tune” menu, which is pretty useful for adjusting it. I tried it, and it defaults to 0.001 steps, which is more than a little annoying. So you might try to increase the multiplier to 10, or 25 maybe, but I used it to adjust the final height after installing the auto level sensor (I hope to post something about that soon).
