My question is about the triangle, top left, top right, and center of cutting bit.
The calibration process sets the distance between 12 o’clock of the top sprocket teeth, which I presume is meant to be same as shaft center to center distance.
From this the software calculates how much chain on each side to pay out to achieve any x, y location of the bit center point.
Yet the actual top left and right triangle points could be considered the separation point between the chain and the sprocket. If thought about in this manner a different triangle is created.
On setups where the chain first goes over the top of the sprocket from the sled, the separation point moves left and right of shaft center, and up and down from shaft center, depending on the sled position.
Same type of separation point movement on the other sprocket, but only the same as the other sprocket when sled is at left to right center at any height.
This means the “triangle” of the two sprocket separation points and bit center is in total motion at all 3 corner points.
(Same concept for chain under first type of construction, but different specifics.)
Given all of this, my question is to ask if the software in any way calculates / considers this when figuring out how much chain to pay out.
( I understand chain sag and chain elongation are additional adjustments that I’ve seen discussed)
