It is a pity you did not get this merged. The argument about accumulating error due to use of relative coordinates is silly. There are 4 decimal places after the dot in the *.gcode files. This may lead to volume error of about 2.4e-4 mm³ per one E movement. But filament diameter typically varies at least in the range like 1.74 to 1.76 mm. This leads to error of about 5.5e-2 mm³ per one 1 mm of E movement. That is about 200 times more. We should always use only relative coordinates for E movement (and absolute only for X/Y/Z movement). No need for an option in GUI.
