Can I assume the "fix" also reduced some of the DAA "power" ?
No, the fix didn't reduce the effectiveness of DAA.
The bug was an oversight when I implemented DAA. Adding DAA meant that the deceleration of a move was no longer always the same as the acceleration; so I introduced a new deceleration move parameter, and I went through the code changing "acceleration" to "deceleration" where required. At that time, CAN support was experimental and not released. Unfortunately I was using a standard build configuration without CAN support when I made the change for DAA, so the "find all references" command in Eclipse didn't pick up a reference to "acceleration" in the CAN-specific code that should have been changed to "deceleration".

@jbarros, please try the latest unofficial 3.3beta main and expansion board firmware. It solves all the issues we are aware of except for a very slight reduction in actual vs. requested extrusion.
Per your previous comments, rounding issues?
Do you know the loss % and do you believe it's fixable? -

Do you know the loss % and do you believe it's fixable?It was well under 1%. I think one user reported it as 0.18%. I've already fixed it for the case that pressure advance is not in use.
