Extruder not extruding filament

rodriguezmf1250

Just got repetier on the davinci 2.0 duo, when i send the gcode to the printer it will run but not extrude. There are E0 codes in the gcode, am i missing something else?

Repetier

Make sure dry run is disabled. Make sure extruder is hot. Check if steps per mm in eeprom is set correct. Check if extrusion mode is matching slicers output, relative or absolute. Normally slicer will make it correct if you do not override it.
That are the normal reasons to not extrude.

Thank you, I will check all this, I'm kinda new to this so hopefully I can find all these settings. Thanks again

I am encountering the same issue - just loaded Repetier onto a da vinci duo and no filament is coming out of the extruder. Can manually get filament when using the load function from the menu, but not when trying to actually print. What did you do to resolve your issue?

Repetier

Did you enable heater first? If temperature is below a set temperature it will not extrude.

Has anybody here managed to get the extruder working i am now in the same boat.

Can manually extrude but not when i send a print to the printer

Any help and advice would be greatly appreciated.

Dry Run - Disabled
Heaters always preheated
Bed heated

Repetier

Make sure you send the M code for absolute/relative extrusion according to slicer settings. Especially if slicer is in relative mode and you have activated absolute extrusion there will be nearly no extrusion.

As a test if extrusion is working at all heat up to temperature and send
G92 E0
G1 E10 F600

That extrudes 10mm equivalent of filament regradless of mode. Then you know motor is working as well and it is mode problem.

I am in the same boat.

flashed 0.92 https://github.com/luc-github/Repetier-Firmware-4-Davinci<br/><br/>can manually get it to spit out filament, but not when it should be printing

im ad 230c for extruder and 90c for bed

it worked before i flashed.

Repetier

Can not say much about that fork, but check eeprom settings. If e.g. acceleration, max speed or steps per mm is 0 or NaN it won't move in our firmware, so there it would also be the case. Depending on changes eeprom might be wrong after reflash so you need to reset it to default values.
