Repetier Host output Transformation matrix

Good morning

Transformation matrix: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000

I have not found documentation of how to interpret the values reported in this string.

Can you explain them?
Where can I find documentation about it?

Thanks

  • These are the values of a 3x3 rotation matrix that convert the send coordinates to the rotated coordinate system to compensate bed rotation in firmware. With only 1 in diagonal it does not change anything.
  • Good morning

    Because with only 1 diagonally nothing changes ?
    In order not to change anything, shouldn't they all be zero ?

    Thanks
  • No. In vector math Pnew = Trans*Pold - with diagonals 1 Pnew and Pold stay same. All 0 means Pnew is always 0,0,0.

    When you run G32 the output is more easy to understand. There you see parameter a, b and c as equation for Z correction depending on x,y. I think it is Zcorr = a * x + b * y + c
