[Clicking on Ultimater 2 Extende while print head is moving along Y-Axis]

So tonight while running a few test prints - I noticed that the rod is pushed out one side quite a bit!

See here:

 

At one point - it actually came off the ballbearing and was totally off the frame.  I picked it up and placed it back in the frame/ballbearing.

But one side continues to protrude out of the machine.

This might indicate that I have a rod that's slightly bent I think.  If I press it in, it just bounces back.

My guess is that the either the rod is slightly bent.  Or whoever assembled it didn't do such a good job.

See here:

 

Should I just loosen the grub screws and re-align it?

Sorry you have to turn up the sound.

[Clicking on Ultimater 2 Extende while print head is moving along Y-Axis]

So I did just that and I think I isolated when it does it .. at first I thought it wasn't doing it when I moved it powered off / by hand. But if you move it with a little more speed the clicking is present (yay! one step closer).

I'll try to post a video to show what I'm seeing.

I don't know how UM printed the test piece and tested your printer though

I was really thinking the same exact thing. I can only imagine it shifted in transport. But it certainly didn't seem like it could have (the screws were tight tight). A little disturbing.

3dphreaks - this is a good find - I will remember to let other people know.  I don't know how UM printed the test piece and tested your printer though :(

Could you please mark your own answer - the one with the nice youtube link in it as the "correct answer"?  thanks!

Thanks gr5 - but the system doesn't allow me to select "Best Answer" for my own posts. Unless there's something I'm missing (sorry, new here). All other posts have that option but mine do not.

Look carefully at the belts on the pulleys. Does it look like any of them are riding up on the pulley and then snapping back down?

Also, just for clarity, the Z-axis is the bed. The head is X/Y. I'll edit the title of your thread.

Thanks for the clarification Robert.

I just checked .. none of the belts are snapping back down or riding up.

I wish there was an object I could print that can isolate the exact motion.

[Clicking on Ultimater 2 Extende while print head is moving along Y-Axis]

Thanks - I tightened the grub screw (they were all pretty tight already) and checked the pulleys. The problem is still happening but I did make other observations:

 

• It doesn't happen when the print head moves slowly - only when it gets up to a decent printing speed.
  
• It is definitely NOT the feeder mechanism in the back of the machine.
  
• It happens when it passes a specific point of the Z Axis.
  
• It might only happen at certain points of the X Axis.
  

 

 

My guess is that its not a pulley or a screw (otherwise it would be more consistent) - it would happen in more places and even at slower speed.

I really wish I could isolate the sound with some better accuracy.

Anything else I can try?

Hmm it does it all the time now .. on every print include ones that was working previously.

:-(

Thoughts?

[Extruder motor skipping - never feeds filament into the bowden tube]

Make sure the filament is reasonably straight at the end. If it has a bend it may not feed into the Bowden tube correctly. ( although sharpening the end should have done the trick)

I tried this and it still didn't work - but THANK YOU for replying. I do really appreciated it:

 

 

Filament not feeding UM2XT.

Could be that the Bowden tube on the feeder end is not all the way down into the receptable. This can make the filament crash into the end of the Tube and not entering it.

Reinsert the Tube by removing the horseshoe, press down the circular clip holder, and wiggle the tube until it falls into place, If I am right ca 5mm more than it is now, maybe?

Cut a piece of filament 10cm. Make it pointy at the entry end, and square flat in the back end. Straighten it as best as you can.

Try feeding that manually, wiggeling it to make it enter the hole inside.

If that works, then drag it out again and feed from spool. Here also help it by holding it vertical into the feeder.

Use in Advanced "Move Material" for all this.

Thanks for responding - the worse feeling is if you post something and no on can help. So definitely THANK YOU. In my case the filament never made it past the motor axle (never past the tension block).

[Extruder motor skipping - never feeds filament into the bowden tube]

And I totally did the pointy filament thing. But once it got to a certain thickness (again stock stuff from the box), the motor would seize.

Thanks for the reply guys! Really appreciate it. My fix worked and maybe it can help someone else in the community if they are out of other options.

[Extruder motor skipping - never feeds filament into the bowden tube]

I think I found the problem .. after a lot of reading and looking at the mechanism, I fixed it by shifting the housing to the tension block for the feeder.

All the literature and people saying "just use force" was wrong (in my opinion).  It really felt like if I used more force, I would have broke it.  There simple wasn't enough space for the standard filament (using only what came in the box straight from Ultimaker).  That, and the tension spring (which I checked) was WAY WAY too strong.  There was no way a motor was going to shift the tension block back.

This was my fix - and since then its been feeding fine.

My U2E just started making this loud clicking noise as the print head moves along the Y-Axis.  This is what is sounds like:

 

It wasn't doing this before.  Although this is the first print I'm doing in .1mm.  The print started off fine too for about 30 minutes.  But then the clicking started.

Wondering if anyone has any insight to this.

[HBK Linear Bearings Clicking]

Can someone answer - is this the same clicking you heard:

 

[Extruder motor skipping - never feeds filament into the bowden tube]

Hello - I just got my U2Extended today. Very excited.

I went through the set up wizard and watched several videos. My problem is that filament won't feed. When I push it up into the feeder motor, the motor skips. I've tried to applied a reasonable amount of force, but that only causes the motor to skip more.

I've read through the articles and tried to lower the tension setting. No help. All settings results in the same problem. I even tried to "sharpen" the filament so the end is very flat (and gradually gets back to the original thickness). Still no luck - at a certain thickness, the motor just skips.

Can someone please help?

Thanks,

DHC
