RapMan 3.1 Dual head extruders and material settings

[Sergey Afonin]

Dead friends,

I use RapMan 3.1. Dual Head. I never had success in printing two materials in one model. The issue is time and matrial consumption. I guess it is connected to slicer settings.
Printer heat up exptruder from warm to working temperature and does material purge before printing new material on each layer. It takes a few minutes to heat and some portion of material to purge. I have extra hours and meters of filament for printing in two materials. Action sequence for example:
- heat extruder one;
- purge extruder one;
- print by extruder one;
- cool extruder one to warm temp;
- heat extruder two;
- purge extruder two;
- print by extruder two;
- change layer;
- cool extruder two to warm temp;
...... and again from beginning...

instead of (when printing in one material)
- heat extruder one;
- purge extruder one;
- print by extruder one;
- change layer;
........ no full loop, print and change layer only;
- cool extruder one;

How to you solve this issue?

Regards,
Sergey
