how to reverse extruders

rockyrude

I have flashed my davinci 2.0 with repetier. The only issue I have left is the extruders are reversed. Is there a setting I am missing?

Repetier

Direction comes from this setting:

// set to false/true for normal / inverse direction

#define EXT0_INVERSE false

so set it to opposite or rotate motor connector 180°.

rockyrude

Is this setting in the configuration.h file? Do I set it to true?

Repetier

Yes it is in configration.h and you set it to the opposite of what it now is.

Thank you

rockyrude

Can I just modify the value and compile/upload to my eeprom or do I need to clear the eeprom first?

Repetier

You upload to flash, not eeprom. eeprom can stay and will normally with such small change. No problem here to be expected.

I worded my question incorrectly, I am looking to reverse extruder 1 and 2.

RAyWB

so you mean to swap extruder1 and 2 ?

so extruder 1 shall be extruder 2 and extruder2 shall be extruder 1?

rockyrude

Yes, the firmware has extruder 1 on the right. I need it to be on the left.

rockyrude

Sorry,had it backwards, extruder 1 is on the left, need it on the right

Repetier

So extruder 2 is now on the right? Just swap all config values between extruder 1 and 2.
If you do not care about numbering just position of second extruder give second extruder a negative x offset so extruder switch gets correct positions.
