3 Extruder problem

Thank you for the wonderfull piece of software that you share with us.

I am using Repetier-Firmware configuration tool for version 0.91 Rev 4 and the latest Repetier host software V0.95E on a delta printer (with RUMBA board). I want to run 3 extruders(filamentfeeders) into one heaterblok with one nozzle. In the pins.h file I changed the HEATER_2_PIN and HEATER_3 _PIN to HEATER_0_PIN value of 2 and the TEMP_2_PIN and the TEMP_3_PIN to the TEMP_0_PIN of 15. Previously was able to do it with 2 extruders but with the three I have the following problem.

With the firmware loaded (I can set the temperatures for all three extruders and extrude all three with Repetier Host but on the RepRapDiscount smartcontroller only the temperatures of the first two extruders are visible.



On the smartcontroller I can only select and extrude with the first two Extruders.(extruder0 and extuder1)
If you select the second(shown as extruder1) or the third(which is shown as extruder1) both are highlighted and only number two(extruder1) can be used to extrude
Edit: When I select the last extruder in Repetier Host there are none selected in the smartcontroller boxes.

Any help will be appreciated

I attached the configuration.h and pins.h files if that can help.

The uimenu is only configured for up to 2 extruder. While more extruder work, the menu needs some modifications if you have such an extruder. I'm not sure if a selector for a 3rd extruder is implemented, but that is easy to change. For visualizing the temps there are already strings to show all temps, but you need to modify the structure to include it.

Thank you for the quick response. Although I can help myself to a certain extend with programming I am at mercy here for someone with greater knowledge to help me here. Will the sellers of the smartcontrollers please help out!!!!!!!!!!!!!!!!!!!!!!!!

The menu system is very flexible and easy to modify. You will need to edit uimenu.h which has some instructions in it. You can choose to modify the current "page3" and add the 3rd extruder line or even add a new page, look at the top of the file there is a lot of information you can potentially display.

In UIMenu.h you will need to scroll down to around line 178 (in my v0.91) which looks like

UI_PAGE4(ui_page3,UI_TEXT_PAGE_EXTRUDER1,
 #if NUM_EXTRUDER>1
   UI_TEXT_PAGE_EXTRUDER2
 #else
   ""
 #endif
 #if HAVE_HEATED_BED==true
  ,UI_TEXT_PAGE_BED
 #else
  ,""
 #endif
 ,"%os");

Looking at you screenshot above i assume you dont have a heated bed, so you could simply add the line where the heated bed temp would otherwise be shown. If you look in uilang.h you can see the definition:

#define UI_TEXT_PAGE_EXTRUDER1     "E1:%e0/%E0\002C\176%o0"

you can then add a new definition (in uilang.h) to look like:

#define UI_TEXT_PAGE_EXTRUDER3     "E3:%e2/%E2\002C\176%o2"

Then you can change the first code block above (in uimenu.h) to look something like (with all the #if etc removed):

UI_PAGE4(ui_page3,UI_TEXT_PAGE_EXTRUDER1,UI_TEXT_PAGE_EXTRUDER2, UI_TEXT_PAGE_EXTRUDER3  ,"%os");

Just alter it to suit you needs, if you want to add another page just follow the examples in the file.

@sdavi - Thank you for the help. Will try and get it to work - if not will certainly get back here. It is not so easy if you do not work with code on a regular basis.

Thank you Repetier for the hard work and quick response to queries. I got my first prints from the hotend with the 3 colour feeder and one heaterblock. From the software side I still need to get the smartcontroller problem sorted but it is running direct from Repetier Host without problems.

Amazing creativity.
Would you mind sharing with us a few pictures of your 3-colour feeder and maybe how you intend to use it?

Still a few small things to sort out but will most certainly post some pictures in the next week or two. I received so much from this forum and it will be a pleasure to share some ideas.

This issue sorted out
In the uimenu.h replaced the following line

#define UI_MENU_EXTCOND &ui_menu_ext_temp0,&ui_menu_ext_temp1,&ui_menu_ext_temp2,&ui_menu_ext_off0,&ui_menu_ext_off1,&ui_menu_ext_off2,
&ui_menu_ext_sel0,&ui_menu_ext_sel1,&ui_menu_ext_sel1,

with

#define UI_MENU_EXTCOND &ui_menu_ext_temp0,&ui_menu_ext_temp1,&ui_menu_ext_temp2,&ui_menu_ext_off0,&ui_menu_ext_off1,&ui_menu_ext_off2,
&ui_menu_ext_sel0,&ui_menu_ext_sel1,&ui_menu_ext_sel2,
