Solved (Please help) Extruding Problems

i'm sorry i'm not following what your issue is. It wont extrude ? but if you turn the wheel it extrudes is your issue? please try to elaborate so the rest of us have and idea of whats going on. maybe a numbered list of what happened or is not happening?

 

Can you upload pictures of the hotend ? I'm imagining something must be either assembled wrong or a wierd partial jam. Do you have your tube installed , whenever I have extruder issues I remove from the carriage and run filament through it while it lies on the bed, if it still messes up I remove the nozzle and see if it still messes up. If it doesn't mess up anymore I either torch the nozzle to get the jam out or replace the nozzle with a spare

 

Hmmm. That is an odd one.
If you want to troubleshoot it I'd suggest starting by swapping the extruder (electrical connection) with one of the other Axis (X, Y, something else) stepper motors and seeing if driving that axis makes the extruder stepper run. If you swapped the connector from the X axis to the extruder then tell the software to move the X axis and see if the extruder runs/turns.

If it does then the problem is likely the stepper driver on the RAMPS board (the one for the extruder) just not putting out enough current. Either try to tune it or replace it.

If it still does not turn then it may well be a flaky stepper.

 

I thought the issue was when turning the extruder by hand? As in this does it with the steppers disabled?

 

Yea, @max longstaff needs to be a lot more clear on exactly what is happening that is surprising...

 

That darn devil hiding behind the details lol

 

For a long time I was convinced mine as possessed by 10,000 demons, but that's another story

 

How does the hobbled bolt look? Is this occurring with all filament? Ex pla and Petg are doing the same thing etc. what temp are you using ? The only thing I can think of is the filament is either 1 binding up causing it to stop extruding (should notice when you remove the filament after it stops extruding). Or 2. Your settings(either temp or tension ) arnt right.

Examples of helpful information for us Americans would be temp settings, what kind of filament, did it do this before the e3d or only after the e3d install.


If it's doing it with the stepper and by hand but works by removing the hot end and feeding by hand then all I can think of is its a tension on the hob, something in the hinge(bearing froze up/missing or pin missing or just plain broken) something wrong with the hobbled bolt etc. pictures are very helpful and look forward to seeing them. It's a very unusual issue

 

Probably the demons are just sleeping @mark tomlinson lol

 

Hmm, best guess (although from an American so take it with salt) is that the hotend is not quite correctly assembled.
If the heatbreak is mis-positioned between the heat sink and the heater block then you can get some weirdness. It would affect the meltzone and cause odd behavior.

Also, what size heater core are you using?

 

The E3D is one of those small-all metal units that are sized so that assembly is really important.
Although, I have not seen this behavior so I can't say this analysis is spot-on.

 

No, this is certainly hotend related not feed.

The most common issue I have had around E3D not being assembled correctly is the opposite where the meltzone gets too large and you end up stripping the filament because the melty part crept up too high

 

Gotya. That helps a lot. I understood it as you were using the wade gear (which would include the hinge and hob) to drive the filament. So some things on the e3d to check
1. Is the heat sink tight on the heatbreak
2.is the heatbreak tight on the heater.

If yes to both of suspect the tube is not seated correctly or has a wierd burr on it (mind did on both sides).

I'd remove and reassemble as a sanity check

 

They should be snug... nothing loose.
