3rd extruder issue
For some time I have been trying to enable 3rd extruder using Extruder Extender connected to:
on AUX2 RAMPS 1.4 board.
For some reason, when I try to enable 3rd extruder (NUM_EXTRUDER 3) and copy EXT1 settings to EXT2 replacing only port numbers, when ever I try to extrude anything all extruders freeze up and do not move (but they are under power, not disabled).
As I am trying to enable 3rd extruder for Color mixing, EEPROM values for extruders are set (T0 only EXT1, T1 only EXT2, T9 only EXT3).
Does not meter which extruder I try to move first, after any extrude all extruders are powered up and freezed. No movement have been made. (* This is tested when heatend is above 200C).
If I reduce number of extruders (NUM_EXTRUDER 2) all is working fine.
I have tried to only replace EXT2_STEP_PIN, EXT2_DIR_PIN, EXT2_ENABLE_PIN with new ports - no luck
I have tried to add in pins.h:
#define ORIG_E2_STEP_PIN 40
#define ORIG_E2_DIR_PIN 42
#define ORIG_E2_ENABLE_PIN 44
#define E2_PINS ORIG_E2_STEP_PIN,ORIG_E2_DIR_PIN,ORIG_E2_ENABLE_PIN,
Still not luck.
Only ting that works correct in setup with color mixing and 3 extruders is enable/disable stepper motor. Again, when I reduce same setup to 2 extruders all works fine.
Today, same setup is tested on currect 0.92.8 source trunk from 16.3.2016.
Any idea where to look for issue ?
