Extruder temp issue

  Guys? My issue is so strange?

  Seems more firmware related, What firmware are you using and what does M105 return. You need to enable file loggin in preferences->general to see the output in the log file.

  Thank you for your answer.
  I'm using the RepRapPro version of Marlin from their github [ last update was 6 month ago].
  https://github.com/reprappro/Marlin/tree/multimaterials
  If it's a firmware issue, why it would appear only from v1.x of repetier host, and what could i do to fix that?
  
  I will do a m105 as soon as my print is done.

  Up
  
  I forgot that i made the m105 control every 5 sec in printer option, and actually in repetier 0.90c it's my only way to see my extruder temp, and i don't have that problem of bed/extruder temp

  Ok, someone has broken your firmware by adding a space after T0: T1: T2: . There has to be no space after the : sign!

  There should also be no space after / as seen in bed temperature. And since when are they outputting -273°C as target temperature?

  
  

  Where did you get this firmware from and what firmware is this?

  I downloaded the original firmware (see previous post).
  The -273 comes from disabled extruders (i only used T0), so there is no target temp.
  
  And i don't know where in the firmware i have to change something.

  I haven't written the code as well. You can simply ignore the error since it has no influence on the result, just wrong display, or use original marlin not a old form or use a different firmware or find the routine which outputs temperatures and remove spaces there. I would search for 105: and from there see where it goes to.

  \o/
  
  You are a life savior
  Thanks to you i was able to find the code part that was messed up and after a night of tests i finally get it to work, it even solved my bug with 1.x repetier-host. Everything is perfect
  
  The originally messed code is

  #ifdef REPRAPPRO_MULTIMATERIALS
        SERIAL_PROTOCOLPGM("ok");
        for(int e = 0; e < EXTRUDERS; e++)
        {
          SERIAL_PROTOCOLPGM(" T");
          SERIAL_PROTOCOL(e);
          SERIAL_PROTOCOLPGM(": ");
          SERIAL_PROTOCOL_F(degHotend(e),1);
          SERIAL_PROTOCOLPGM("/");
          SERIAL_PROTOCOL_F(degTargetHotend(e),1);
        }
        #if TEMP_BED_PIN > -1
            SERIAL_PROTOCOLPGM(" B:");  
            SERIAL_PROTOCOL_F(degBed(),1);
            SERIAL_PROTOCOLPGM(" /");
            SERIAL_PROTOCOL_F(degTargetBed(),1);
        #endif //TEMP_BED_PIN  
        #ifdef PIDTEMP
          SERIAL_PROTOCOLPGM(" @:");
          SERIAL_PROTOCOL(getHeaterPower(tmp_extruder));  
        #endif    
        SERIAL_PROTOCOLLN(""); 
  #else

  
  
  And this is my pimped working code (with some google help too)
  

  #ifdef REPRAPPRO_MULTIMATERIALS
          SERIAL_PROTOCOLPGM("ok ");
          for(int e = 0; e < EXTRUDERS; e++)
        {
          SERIAL_PROTOCOLPGM("T");
          SERIAL_PROTOCOL(e);
          SERIAL_PROTOCOLPGM(":");
          SERIAL_PROTOCOLPGM(" ");
          SERIAL_PROTOCOL_F(degHotend(e),1);
          SERIAL_PROTOCOLPGM(" /");
          SERIAL_PROTOCOL_F(degTargetHotend(e),1);
          SERIAL_PROTOCOLPGM("  |  ");
        }
        #if defined(TEMP_BED_PIN) && TEMP_BED_PIN > -1
          SERIAL_PROTOCOLPGM("B:");
          SERIAL_PROTOCOLPGM(" ");
          SERIAL_PROTOCOL_F(degBed(),1);
          SERIAL_PROTOCOLPGM(" /");
          SERIAL_PROTOCOL_F(degTargetBed(),1);
        #endif //TEMP_BED_PIN
  
        #ifdef PIDTEMP
          SERIAL_PROTOCOLPGM(" @:");
          SERIAL_PROTOCOL(getHeaterPower(tmp_extruder));  
        #endif    
        SERIAL_PROTOCOLLN(""); 
  #else
  
  
  

  It shows me a more readable M105 command

  16:37:23.010 : ok T0: 26.6 /-0.0  |  T1: -273.0 /-273.0  |  T2: -273.0 /-273.0  |  B: 28.4 /-273.1 @:0

  I'm wondering it works with th ehost since you left the spaces i mentioned included. I'd do it this way:

  
  

  #ifdef REPRAPPRO_MULTIMATERIALS
          SERIAL_PROTOCOLPGM("ok ");
          for(int e = 0; e < EXTRUDERS; e++)
        {
          SERIAL_PROTOCOLPGM("T");
          SERIAL_PROTOCOL(e);
          SERIAL_PROTOCOLPGM(":");
          SERIAL_PROTOCOL_F(degHotend(e),1);
          SERIAL_PROTOCOLPGM("/");
          SERIAL_PROTOCOL_F(degTargetHotend(e),1);
          SERIAL_PROTOCOLPGM("  |  ");
        }
        #if defined(TEMP_BED_PIN) && TEMP_BED_PIN > -1
          SERIAL_PROTOCOLPGM("B:");
          SERIAL_PROTOCOLPGM(" ");
          SERIAL_PROTOCOL_F(degBed(),1);
          SERIAL_PROTOCOLPGM(" /");
          SERIAL_PROTOCOL_F(degTargetBed(),1);
        #endif //TEMP_BED_PIN
  
        #ifdef PIDTEMP
          SERIAL_PROTOCOLPGM(" @:");
          SERIAL_PROTOCOL(getHeaterPower(tmp_extruder));  
        #endif    
        SERIAL_PROTOCOLLN(""); 
  #else

  I know, i tried removing all spaces but it was helpless [and ugly log display].
  
  I think the broken part was just

          SERIAL_PROTOCOLPGM(": ");
          SERIAL_PROTOCOL_F(degHotend(e),1);
          SERIAL_PROTOCOLPGM("/");

  But i wanted to keep a space between ":" and the temp display in log file so that why i added

          SERIAL_PROTOCOLPGM(" ");
  

  And strangely it works.
  But if i remove the sapce in

          SERIAL_PROTOCOLPGM(" /");

  Then i have nothing in repetier
  
  
  The same was with bed space.
  If i try

          SERIAL_PROTOCOLPGM("B: ");

  The temperature is gone in repetier
  
  I can understand a little of code but that was strange to understand [even now]
