Dual flows for dual prints

[3dmakeme 0]

Hi,

Could it be possible to have 2 different flows on dual prints ?

I have 2 different extruder heads with different gears and as Marlin only manage 1 extruder flow in the (standard) firmware, i need to compensate with different flows but Cura only offer 1 flow on dual prints.

Thx

Marlin should be able to manage individual flows for each extruder by using the 'T' option in the M221 command. You can also specify them in the TweakAtZ plugin.

On my firmware I can change the flow1 and flow2, I used the firmware generator from Amedee -> https://bultimaker.bulles.eu/ it works great

Take care - as fas as I know the second diameter is not propperly implemented in the calculations...

That's only in Cura. In Marlin, the diameters of all three (four?) possible hotends are properly implemented. The flow is anyway an independent scaling factor and not the same as is used for the diameter.
