Filament Transport doesn't work

Post by toonlumberjack »

With Felix Dual 3.1 Both filament transports don't work.

1) Checking if Motostepers are defect
Plugged the motor steppers to the functional x/y/Z stepper connection -> They are working

2) Checkec cablebreak
Multimeter did *piep on every wire of the 4. For both of extruder motors

3) Checkec Board Pins on voltage change
x / y / z do change voltages if moved via software
e0 / e1 did NOT

==> Conclusion: The board is broken. Any other ideas?

1) Is there a source for this motor steppers? the company who produce them isn't so keen on datasheets and you find only similiar ones. Probably similar ones don't work here.
2) Probably the ic stepper driver ICs are okay. and the pins on the atmega 256 are messed up somehow. There is no schematic of the board in the download section. Does anyone have an idea of getting one?

Best regards

Hi toonlumberjack,

Are the heaters of the hot-ends above 150degC? If not the extruder motors are blocked by the firmware.

Oh my god ...Yes you are right. Found the the part with it

#define EXT0_WAIT_RETRACT_TEMP 150

Due to teardown i havent connected the extruders hotends. Will check this.

Will report about the test

thank you very much for now.
