RRF Feature request: option for coarser "alter" on 12864



  • The "alter" feature in the 12864 display menu system, while giving very fine control over the altered value, starts to feel slow and too fine when trying to control things like long axes.
    I suggest this could be solved by allowing for negative values of the D parameter. This would make the "alter" element ignore a given number of least significant digits.

    For example:
    alter D-1 N510 would control the X axis in steps of 10, ignoring the least significant digit
    alter D-2 N510 would control the X axis in steps of 100, ignoring the two least significant digits
    etc
