retur

But I realized that this option just let us add something before switching, but it does not change every M101 for M201 for the second extruder and every M108 S(extruder speed) need also to be replace by M208 S(Extruder 2 speed) The M103 stays the same for any extruders, since it mean turn off all extruders I would need some help for that I can not change the software code by myself.

If you go to Expert > select "Full setting" go to "Start/End-GCode" then you have "Preswitch Extruder" and "Post switch Extruder" The code is to be added, I am going to run a file with my printer slicer and try to see what is supposed to be added.

For the start code, I changed it for something that my printer was using: ^Firmware:V1.07 ^Checksum: NO G21 G90 # Select Extruder 1 M104 S{print_temperature} P1 M542 M551 P51 S150.000 M227 P51 S80 M228 P0 S51 M543 Also I have to remove an other line in the file that generate a big clump of plastic before the beginnig of the parts, the line is: ;enable auto-retraction M227 S11520 P11520

Also I search for M208 wich is setting extruder 2 speed, and there was no such command in the file. Is it ready for dual extruders ?

Hey Guys, I'm really interested in Cura for bfb. I've try the experimental version of cura for bfb, I got error at line 19. It was because of M103 mean turn extruder off, and it was not turn on yet I removed that line and it worked. But it didn't print in dual color as as i asked to cura asked It tryed to preheat the extruders one at the time, and when heating one the other cool down. Until got an error message It asked if I want to continue and it printed in one color.
