extruder does not work repetier v 1.0.4

i build the 1st 3d printer and the extruder does not move can you help me what is the reason

Was you extruder hot while trying? Extruder will not work when cold except if you explicitly allow it setting allow cold extrusion with M302 S1

Also check eeprom values in case first upload did not have set them as you want. Or restore to config settings with M502 M500

Last thing is make sure dry run debug mode is not active - that also prevents extruder motion.

i move it manual but not move , and i trying when hot with m302 s1 and not move why? where is the dry run , and how know is active or no ? anther thing i used ramp shield 1.4 and did not use eeprom use the eeprom are important ? my problem is still

You see it in the host console if printer switches into dry mode (happens when temp. sensors do not work). So check output in console/log. You can disable it with M111 S6 Adding 8 to S enables it. EEPROM or not is not relevant here. When printer is just enabled or reset can you move extruder motor by hand? If not and it feels like motor is on you need to change

define EXT0_ENABLE_ON 0

to 1. Some motor drivers enable power on 1 some on 0. Also swap with x motor if X works to rule out that driver is defect.

[qusai210]

i change the #define EXT0_ENABLE_ON 0 to

define EXT0_ENABLE_ON 1

still the problem what is the happen i used pronter host

[repetier]

Are all drivers identical? Then set EXT0_ENABLE_ON on same value as X axis.

Connect motor to x axis motor to see if it moves there. Especially after you already swapped the drivers. That way you now motor and driver work.

Last test is to connect X motor to E0 and make config use the E0 socket for motion and set Extruder 0 to use X motor socket instead.

If then extruder moves and X motor not I would assume the socket is defect and you should switch to using E1 socket instead.

repetier the problem in code all driver the same A8499 and i swap between x motor and extruder in config (just) ,,, when sweep motor extruder work and x not work notice i used the standard config in web site to fix the problem , used v .92.9 and switch to E1 in 2 version but still the problem can you give me new config to fix the problem or help me to fix them thank you

[repetier]

You can just try the default configuration in config tool just with your board selected. Quite unlikely the both extruder ports are defect and with swapping you already tested that all other hardware is working as well. If you also send M302 S1 before testing extruder I see no reason why it should not work from here. So please check if you really did all the things I said and all tests are positive. So a fresh version with basic settings for testing is the only thing to test I can think of.
