[Cura with BFB printers]

So what program are you using? I compared prints with Cura and Axon , Cura is doing much better. You could write what you use, and send some profiles?

[Cura with BFB printers]

I looked today Cura source , I found something like this:

 

   if (flavor == GCODE_FLAVOR_BFB)   {       //For Bits From Bytes machines, we need to handle this completely differently. As they do not use E values but RPM values.       float fspeed = speed * 60;       float rpm = extrusion_per_mm * speed * 60;       const float mm_per_rpm = 4.0; //All BFB machines have 4mm per RPM extrusion.       rpm /= mm_per_rpm;       if (rpm > 0)       {           if (isRetracted)           {               if (currentSpeed != int(rpm * 10))               {                   //fprintf(f, "; %f e-per-mm %d mm-width %d mm/s\n", extrusion_per_mm, lineWidth, speed);                   //fprintf(f, "M108 S%0.1f\r\n", rpm);                   *output_stream << "M108 S" << std::setprecision(1) << rpm << "\r\n";                   currentSpeed = int(rpm * 10);               }               //Add M101 or M201 to enable the proper extruder.               *output_stream << "M" << int((extruderNr + 1) * 100 + 1) << "\r\n";               isRetracted = false;

 

In the file :

CuraEngine/src/gcodeExport.cpp

Looking at the code Cura has a division at M101 , M201 . Is it possible to add M208 ? I still do not know how to start " preSwitchExtruder.gcode " when I add there a command Cura does not add it to gcode what could be causing this?

Hi

I have a similar problem with the printer BFB 3000 , uses the same settings for the second extruder .

can we pull request together?

yellowshark, there can not be set because this command M101 / M201 and M108 / M208 are in the code many times:

When I type something in addition to preswitchextruder and postswitchextruder Cura does not add this to the code. When I change the code in a file .bfb and I will add the command to change the extruder for the second, further change over all commands M101 , M108 to M201 , M208 - Bfbf 3000 runs on two extruders good. Is it possible to expand Cura to generate a command for the second extruder?

 

[Cura with BFB printers]

I was able to configure Cura to work with a single extruder ( BFB 3000) .

The problem starts when printing on two extruders .

BFB 3000 using the command :

M104 extruder temperature 1

M204 extruder temperature 2

M101 enable the first extruder

M201 inclusion of a second extruder

M108 RPM setting for the first extruder

M208 RPM setting for the second extruder

Where can I change to Cura generate commands for the second extruder M201 , M208 instead of M101 , M108 ?
