3 Extruder problem (no replies)

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.
