Hell, now that i know about it I'm going to have to start working on it
-
No I mean actual tech support from Ultimaker or the reseller that you bought the printer from:
-
Yea, I'm pretty stumped as well. Have you tried contacting official Ultimaker support yet?
-
On other printers I usually take my accel down to 1000 then do a test print and see what it looks like and make more changes from there.
-
Try turning down the acceleration settings, I know it's in Cura somewhere, I'm at work currently and can't tell you exactly where since i'm not in front of cura
-
This may be a obvious question but you said you cleaned the nozzle and feeder, what about the bed? Have you tried wiping that down with some alcohol? You could have gotten some skin oils or maybe some sort of left over gunk on the bed from filament that is causing a problem like this.
-
Haven't tried this before but think it would be possible. One thing that would be super important is to level the bed with the wafer on it or else you'll crash the head, as well as make sure you secure the wafer while printing or it might slide and you'd get a shifted print. Other then that it would probably just be a matter of finding a plastic that would bond to the wafer and well as a initial print temp. Good luck, if you try it post pics of how it went.
-
Yea, i think that's about the same time my UM3 takes on the normal profile.
-
Not sure on this one but i think changing the scale on benchy kinda defeats the purpose, if you scale it down then some of the details of the model that are suppose to be tested don't get printed hence why you may be seeing artifacts, plus the material doesn't get the proper amount of cooling time.
The cube looks like it's picking up a lot of ringing and echo's, I haven't tried on the UM machines but can the accel and jerk be lowered? That's what I would do if this was one of my repraps. Maybe try dropping the speed over all, try a cube at 50 and see how it turns out.

I did this same thing last night. Installed my upgrade, updated firmware and motor was running backwards. Turns out that in cura i still had the UM2 selected not the UM2+. I just deleted the UM2 since I didn't need it and left the UM2+ and updated the firmware again and everything worked. In Cura I believe it's under the "Machine" menu at the top, i don't recall off the top of my head.

Hi all, I had my printer setup and dialed in perfect, gave me no problems. Then I moved, after setting the printer back up I've had nothing but issues. I've checked the visual troubleshooting guide but didn't see anything like what I have.
The problems are very random, if i try to use a brim the first line that prints is fine then it starts getting globby and there's no solid lines. If I try a raft first layer pritns fine then it all goes to hell. I've tried the extrusion test and it printed fine for some reason. I've included a picture of a raft, don't have one of a brim yet. I've tried different materials, temps, speeds, I have no clue what is going on and I'm at my frustration limit.
-
just wanted to add that I had this same issue with the first print I tried with colorFabb white. I then switched material and did another print with no problem. Going back to the white I literally had a dog hair clog in my nozzle (husky owner problems). After cleaning the nozzle I tried the white again, three different UM robots at three different temps (200,210,220) and no hair problems. I did notice that some hair fibers were on the fan shroud after the robot prints when the shroud was clean before printing.

Great job Robert, thanks for putting the work into this, will definitely be a big help for everyone
-
yea i noticed that it got better toward the top which is why i was confused, the second test went way better but the very upper layers thinned out compared to the first test.
-
Just update Cura and firmware to 14.07. Worst test so far i think, I forgot to level the bed after the update so I ran through the leveling and running the test again. Any particular reason why the back side would have a issue like this?
-
After switching to Roberts feeder, best test results yet, no layer spacing at all
-
So things have been better, I downloaded the new cura, updated the firmware and ran the test again, got up to level 9 before I started getting spacing between the layers. I also printed up the low friction spool holder and a new filament guide which I've noticed has taken a ton of tension off the line to the feeder. I'm in the process of printing Roberts alternative feeder to see if I like that one better then the stock.
I switched out the blue pla for clear, i'm playing with the clear just to see what it's like, I'm going to switch again to some grey pla to see how that prints, I've read that the blue stuff is hard to work with. I'll post a print of the grey stuff once i switch it out.

Thanks for the advice Illuminarti, I tried a print last night with the bed at 60 and the print detached from the bed before it was finished. But as long as I know I'm extruding correctly I'll work with the bed and figure out a sweet spot for the temp.
I'll also update the firmware and see what kind of difference that makes.
Again, thank you all for the advice and help, greatly appreciated.

okay, glad to hear that the print is good. Here's the other problems I've been having, I've had some stringing issues recently, especially when the print is done and the head moves away. There tends to be some oozing while the head heats up. When the print starts and the head starts to eject while it's moving towards the build plate the plastic coils up around the nozzle. My biggest problem is when the print starts and what I call the outline is printed, the nozzle doesn't seem to be close enough to the buildplate for the plastic to stick, all the plastic just kinda clumps up on the nozzle until it catches the build plate then gets dragged out along the printing area, but as soon as the main object starts printing everything seems fine. I've tried leveling the buildplate a few time and it didn't seem to help.
Hope all that makes sense. Mind you all this started after I took the head and feeder apart, so I've been thinking that I didn't put something back together correctly.
-
Alright, printed the right file this time at 230c. It didn't turn out to bad, the bottom level is miss shaped, the upper levels are pretty thin and spaced apart and I've got some strings which I didn't have before. What do you guys think?

Hi everyone, I've had my UM2 for about a week and a half now, it was amazing out of the box, I tried my first 7 hour print and at some point the filament broke just after the feeder and jammed up the bottom of the tube. I had to take apart the feeder and the head to get the tube out. I then ran the tube under hot water and yanked the filament through the tube. I put everything back together and have had all kinds of problems since. I ran the 8 - 15mm test and as you can see it's a huge mess. Did I do something wrong when I put things back together? Any advice on improving my print quality?
-
Hi everyone, got my UM2 about a week and a half ago and have been lurking around here for a while but just now posting. I've had a couple of issues that I'm working out but overall it's been a awesome machine.
It is here, the new Ultimaker S5!

Will some of these new features be added to the UM3 to make a UM3+? and hopefully a UM3+ upgrade for us current UM3 owners?
Will current firmware be updated to get more leveling points in auto calibration?
