* Bed Skew Compensation |
|
|
|
* |
|
|
|
* This feature corrects for misalignment in the XYZ axes. |
|
|
|
* |
|
|
|
* Take the following steps to get the bed skew in the XY plane: |
|
|
|
* 1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
|
|
|
|
* 2. For XY_DIAG_AC measure the diagonal A to C |
|
|
|
* 3. For XY_DIAG_BD measure the diagonal B to D |
|
|
|
* 4. For XY_SIDE_AD measure the edge A to D |
|
|
|
* |
|
|
|
* Marlin automatically computes skew factors from these measurements. |
|
|
|
* Skew factors may also be computed and set manually: |
|
|
|
* |
|
|
|
* - Compute AB : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2 |
|
|
|
* - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD))) |
|
|
|
* |
|
|
|
* If desired, follow the same procedure for XZ and YZ. |
|
|
|
* Use these diagrams for reference: |
