Hi,
I have read the documentation [
reprap.org], and I wonder if there is a bug in the doc.
"The I (orientation) parameter tells the firmware which of the 24 possible orientations the accelerometer chip is in relative to the printer axes. It is expressed as a 2-digit number. The first digit specifies which machine direction the Z axis of the accelerometer chip (usually the top face of the chip) faces, as follows: 0 = +X, 1 = +Y, 2 = +Z, 4 = -X, 5 = -Y, 6 = -Z. The second digit expresses which direction the X axis of the accelerometer chip faces, using the same code. If the accelerometer chip axes line up with the machine axis, the orientation is 21. This is the default orientation if no orientation has been specified."
So if the accelerometer and printer axis are aligned it should be 22 in the example instead of 21 or I just don't understand it correctly?
Best, Marcin
