Cura 2.6.69 Flow wrong

When dual extruding the flow values set in cura between extruder 1 and 2 are not correctly passed to the printer.

Also, they are not independent between Extruder 1 and 2 for first layer, but they are for other layers.

Has anyone QC’d this software at all for dual printing??

Also, printing two models at once, the manual flow entered on the LCD to to correct the above issue was overwritten when moving from one model to the next ON THE SAME LAYER. How many flow commands need to be sent to the printer?

Also, the flow rate of extruder #1 did not change back to the correct flow rate after the first layer.

Yet another pathetic error in dual extrusion printing

This time the front extruder simply stopped working and instead the rear extruder started to attempt to print at the lower standby temp in its place.

This new software is garbage.

Is this for a V2 Dual Extruder or a V3?

Neither. Its my own design dual extruder. Working perfectly for a year before Cura LE.
