Hey there! I am using the Azteeg X3 Pro running with Repetier 0.92. So far I was using it with two extruders and everything worked fine. Now I would like to use a third (..forth, fifth..) extruder. Therefore I used the configuration tool to create a new configuration.h file defining 3 (..4,5...) Extruders (EXT0, EXT1, EXT2). Same settings for the 3 extruder motors. With manual control I can still move EXT0 and EXT1 without problems. But When I try to move EXT2, it only works in one direction. Or more precise: Moving EXT2 "up" -> motor is turning to the right. Moving EXT2 "down" -> motor starts turning to the left and immediately switches direction (turning to the right as well). Extruder 4 & 5 (EXT3, EXT4) do not move at all (completely quiet). What I tried so far: - download new firmware - changing stepper drivers - changing motor + wiring - redefining pins in pins.h: pins of EXT0 -> EXT2 pins of EXT2 -> EXT0 -> same problem as before but on the motor connected to the physical extruder 0 port. Motor connected to physical extruder 2 port now works fine. So the Problem needs to be connected to the firmware. Anybody experiecing the same problems? Any ideas what could be wrong? cheers! https://reprap.org/forum/read.php?146,664845,664845#msg-664845 Sat, 11 Apr 2026 06:35:14 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?146,664845,664845#msg-664845 https://reprap.org/forum/read.php?146,664845,664845#msg-664845
