I like this and I would love to come, if it was more close to where I live, or if it would be on a Saterday ? Because I normally work until 17:30 ...
-
I like this guide very much, but I tried to look up the 'stripes issue' I have but I could not find it ? see picture
-
which filament do you use ? I think I had this also with Innofil at 230C.
-
I went to my printerreseller and they helped me replace the spacer. It prints much better now.

I did some new extrusiontests : with the current rol of filament (2/3 full I guess) and with a new rol. Both Innofil. At 230 C. See photos for result : bad or very bad at low speeds 3 and 4, or even 3,4,5,6, and better at higher speeds. The test with the new rol of filament was completely very bad (the test on the right on the picture).
We also have lots of times a thick bulge in the filament; see second photo.
Also grinding of the filament hapens often.

Ah yes, so I went to the Ulti-evening, couldn't be fixed. Brought it to the UM office. The feeder was replaced, the hot end replaced (number 3) and it prints at normal temperatures now, so happy!
Wonder how long it will last.
thanks for all the help...
I have the same problems so I would like to go to this UM Office also to have it fixed. Is it in Holland and can you just go there ?
-
I looked at it but I still don't have an idea. It does not make sense to give such bad results at 3-4. Is it repeatable? Did you watch the feeder to see if filament gets tangled or if it is blocked somewhere on the way?
I think you have two problems here. The one is the bad extrusion and the other is the "banding" which should be related to the z-stage.
As for the z-stage - I'd take it out and clean it. I'd also check if the screw is flat/even and not bent.
The extrusion problem still baffles me. Try another filament brand and watch the feeder (especially at the beginning). Also, do you hear the typical skipping sound when the feeder skips and the filament is pushed back?
The bad result of the extrusion test repeated itself today : again 3 and 4 are very bad and the other speeds look quite good.
I checked the screw : I think it is not bent. I cleaned it and I will do a new test tomorrow.
I already ordered new filament because I ran out but again Innofil ; I will get it tomorrow. I do not hear the sound that you mention. The batch was from last Feb I think ; but I started using it some 3 weeks ago. I kept it in the sealed bag untill then.

You forgot to add the pictures.
Regarding the "banding" - from you description it sounds like the z-screw might be a bit loose. Go into the advanced menu and move the heated bed a few times up and down. Watch the z-screw. Does it wobble much? Also observe if the threads are clean or if there is gunk stuck in there. You could clean it and then add the green grease that came with the printer (only add it to the z-screw).
As for the underextrusion it sounds like the classical teflon piece problem. Maybe you could attach a picture so we can see what is going on.
Did you have a look at my extrusion test result , being very bad at 3 and 4 ? What do you think about it ? Regarding your request for pictures related to the teflon piece problem : what kind of picture do you need , is the picture of the test not what you meant ? Or a picture of the teflon piece ?
-
That's common with old PLA. Order a new batch of PLA. Keep it in sealed bags when not in use. Some people say it's humidity related but I suspect it's out-gassing or something else.
When do you consider PLA to be 'old' ? looks like the batch is from last Feb and I kept in the sealed bag untill I started using it some 3 weeks ago.

Heeft er trouwens iemand ervaring met filament dat te nat is ? wat gebeurt er dan met de print ?
-
Hebben jullie misschien ervaring met Innofil filament ? Ik gebruik hun wit omdat ik dat een mooie kleur vind maar omdat we vaker problemen met verstopping hebben vroeg ik me af of het met het filament te maken kan hebben.

Argh, sorry. Didn't see your last sentence. Here is how to add a picture (btw. the search in this forum is crap. I don't know how many times I written this because I always fail to find one of the (by now) tousand posts about how to add an image...)
1. At the top of the screen click on your name and select "My Gallery" from the dropdown.
2. In top right click on "Upload".
3. Click on "select album" (or create new one if there isn't one).
4. Then click on the "Choose Files..." button and select the images you want to attach.
5. After it has been uploaded click on "Review & Publish" (or something like that).
6. Check if the images have the correct orientation (if not, click on the small corner arrow beneath each image - "Rotate image" to rotate them clockwise) and give them a title if desired.
7. Click on "Finish & Publish".
8. When you post something (in this thread for example), while editing the message, click on the "My Media" button at the top of the input field (to the right of the smiley button).
9. On the left click on "Gallery Images" and click once on your image you want to paste into the post. Nothing happens, the image will be inserted in the text field right where the cursor was.
10. Click "Finished" on the lower right and save your post or edit further.
E.A.S.Y! - I wonder who designed this workflow... Daid I hope it was not you
Tried again ; I created an album now and uploaded pictures. Here are the 3 pictures I mentioned.

Sorry , this did not work: no My Gallery (1) and (8 and 9) image is not inserted either

1: there is no 'My Gallery', only My profile, My Settings, My Content

Hi, I did the extruder test today, because I have problems with my prints since some time. Holes and stripes, at 230 C. When I bought the printer in Feb, it printed fine, even at 210 C. Last april I made a print of my son's head (was very good at 210 C) and I reprinted this same gcode today with 230 C : lots of horizontal stripes/banding (not really sure how to call it, I am Dutch). I added a picture of both prints. I also have holes in prints but not in this one. When I prints slower, mostly I do not have holes, but still have horizontal stripes.
The extruder test is a bit strange, maybe you can explain ? It is really very bad at 3 and 4, then it gets better at 6, 7 , 8 and 9 , and 10 is a bit worse but still not too bad.
Yesterday and this morning before the extruder test, I leveled the bed using the rings. I send you photo's of the last result also : it looks ok to me but I am not sure how to interpret the total ; in the back of the UM it prints a bit less I think ?
Note : tried to add the pictures but I could not figure out how to.... :???:

Hi, did anyone already buy this XTC-3D in Europe ? I am trying via a reseller of smooth-on in Amsterdam but until now they don't have it ?
