I'll try it out -- I'm not with the printer right now, so I'll be sure to check once I am.
-
The shapes are correct, but there are places where an entire line of shell is seperate from the infill. I found a problem, though, and I've already contacted support about it -- the outer cap with EXTRUDE engraved into it is rubbing on both the black molded gear and a few screw heads. Just to be safe, I completely rebuilt the extruder, but nothing seemed to change. Hopefully Ultimaker support helps me out on that one. Prints still aren't doing well.

Hey everyone -
Recently, I started a topic on what I thought was some X-Y inaccuracy (check it out here), and rigs directed me to 3DVerkstan's Ultimaker troubleshooting guide (which was really helpful). I tried out a few of the suggestions that seemed transferrable to my Original +. After moving the X and Y motors down (as the guide suggested), I reprinted - the walls stuck to the infill! Success!
But then, in the next print, it happened again (boo!). I checked the machine over and over, and did the following: re-leveled the bed, moved one of the timing pulleys (I had found it was off-centered), tightened the other timing pulleys, and did multiple atomic pulls and full nozzle cleanouts - took the hotend apart and everything. Everything seemed to make it worse - one of the prints I did didn't even have its shell; it was set to .4mm (my nozzle size) and it didn't even print. Aaah! Also -- sidenote -- a few of the test prints I did were print-in-places, and all of them had fused joints. Not even sure what to do.
If anyone could help me at all with this, I would love it. I'm kind of burned out on the printer; whenever I fix a problem, another comes up. Guess that's just the printing life, right?

Uh-oh. I printed the next part of the chandelier and the same problem came up. I read every article on the website rigs linked, and tried out a few of the suggestions - nothing changed! Aaah! Any other thoughts on what might be going wrong?
Thanks,

Awesome! Thanks for the quick replies, guys. I actually just cleaned out the nozzle using the old acetone/blowtorch method, and that cleared the nozzle out entirely. It might have clogged since then, but I hope not. If I have to, I'll do it again.
Also - I checked out that website and it's awesome! I'll try out some of the suggestions and post the results.

Hey everyone!
After just recieving a bunch of rolls of colorFabb filament for my birthday, I've been printing non-stop for the last week! I'm just starting the Chandelier of Fear project (thing:493016) for Halloween, so that's pretty exciting, too.
But, sadly, with the good comes the bad. After printing the three parts of the Screwed Cube (thing:693892), even though I had tweaked the print settings for each one as I went along, I noticed the same problem on each one: The top-left corner of each one was all messed up. The infill was about half a millimeter away from the shell. I changed a couple more settings like print speed and temperature and printed a new design (a cap for a SodaStream bottle), and the same thing happened - top-left corner had a gap. Again, I changed the settings and printed an arm for the Chandelier of Fear, and the gap actually went all the way through - the shell was at least a millimeter away from the infill.
I gotta say, this one really got me. I have no clue what went wrong other than some X-Y inaccuracy issues.
Here are a couple of print settings I've been using:
Material: colorFabb Black/Silver PLA/PHA
Printer: Ultimaker Original +
Temperature: 225-205 -changed during print, no visible changes
Acceleration: 2000
Print Speed: 40mm/s
Layers: varied from .2mm to .05 - again, no visible changes
Any help would be greatly appreciated!

Hello again everyone,
Thanks for the responses! I was able to get some pretty good quality with the Maker filament, but shortly after, I recieved my roll of ColorFabb which is printing right now with pretty good quality. Not fantastic - just pretty good.
To answer your questions, Sander, I have the metal fan shroud that came with the UMO+. It was running at 100% when the overhangs started drooping. Probably because I had the temperature ramped up so high. Also, I printed the second one at .15mm @100mm/s, and reduced it to 90mm/s during the print, which helped a lot. I'm sure I could have gotten much better results with it at, say, 50mm/s, but I had to turn in that print as a school project. Sidenote: my teacher thought it was the coolest book project she'd ever seen, and gave me an A+ on it
Right now, I'm printing the T-Rex Shower Head (thing:308335 if you're interested - hilarious idea) in ColorFabb. Here are some of the specs on it:
Material: Black ColorFabb PLA/PHA
Head Temp.: 215 (tried 210 but got a lot of underextrusion)
Layer Height: 0.2mm
Shell Thickness: 2.0mm
Speed: 40mm/s
Fill Density: 20%
Support: No
Bed Adhesion: Brim (20 lines)
-
Okay, so the print is going okay, but there are a few problems going on that I can see - the tiny overhangs are looking terrible (because, I assume, of the high temperature), and the lettering on the side isn't looking too hot either. I had to manually change the acceleration value on the Ulticontroller (does anyone know how to change the accel. in Cura? I have yet to find a setting in there), and lowered the speed to 90. Occasionally there's a thump coming from the machine, which I've yet to figure out - could it be the travel? The travel speed is at 250mm/s, which is amazing for overhangs. There might be some loose screws that are causing that - I'll go ahead and retighten everything later. Any other suggestions for getting some better print quality?
-
Got it - printing right now with a slightly downscaled model (so it prints a bit faster) and the higher nozzle temp. Bed is at 60C - that seems to be working. Fingers crossed!!

Hey everyone,
I recently put up a post asking you guys what filament suppliers you guys like to use, and the support on that topic was amazing. I ordered some ColorFabb because of it, and now I'm waiting for it to get here.
Sadly, though, the last six prints I've tried have failed - and, for the record, each print was a 180mm x 180mm x 15mm tall model of the first step on the moon. Each one has had the same problem: Underextrusion. Which, I have to say, really, really sucks.
I've tried the Atomic method for clog removal (which helped a bit), turning up the heat, slowing the overall speed, and increasing the flow. Each one had helped a bit, and the last print I did (which failed ~20 minutes ago) started underextruding at 1 mm up. That print was the best out of all of them: I had increased the heat to 220C, and the first, second, and third layer printed fantastically. After that, the machine sped up, and it immediately stopped extruding. I think it might have been due to grinding, but I haven't checked that yet. That has been the case in the last five prints, so I'm sure this isn't any different.
Here's a list of specs so you guys can figure out what horrible mistake I've made quicker:
Ultimaker Original +
Bed Temp: 70C
Head Temp: 220C
Print speed: 80mm/s
Flow: 100%
Layer Height: 0.15mm
Acceleration: 2000
Filament Used: MakerGeeks - Maker Filament PLA
Thank you all for reading, and for your help with all these problems I've been having recently.

I think I figured out what happened, and it'll make me look like a complete and total idiot: I had the wrong machine set up in Cura. It was set up for my old Robo3D, which I returned in favor of this one. I reprinted with the right machine, but it still happened - just not as extreme. It still hit the back right clip (to answer your question), and no, it still homes in the front left as it usually does. The entire model is off-centered, and it's still printing in the back right of the printer, which hits the clip. I haven't had any success with any x-y max prints. Even when I scale it down to 170 x 170mm, it does nothing.
Thanks for the help,

Hello everyone!
After a bit of time working on my printer (just your average maintainance - bed levelling, extruder check-up, etc.), I tried something I never had before: printing an object that maxed out in x-y. Well, it didn't max out theI plate (it was 195mm square on its bottom), but it got pretty close to it.
Anyways, here's the deal with the print: I sliced it with my normal settings (skirt included) and started printing. It homed, as per usual, then started printing the closest side on the x axis. It went fine, then it hit the edge. I watched it go along the edge, then it hit one of the bed clips. Acting much like a drunk guy, it continued along the edge of the print, off-center to the right. I stopped the print by going into the Ulticontroller menu, and it did something it never had before: it moved the head to the left back corner (not homing) and continued to ram into the corner without stopping. I quickly shut off the machine, and went into full problem-solving mode.
I re-leveled the bed, checked the .gcode, re-sliced it (without the skirt), and tried reprinting. Same problem. Then, I checked the extruder, checked the motors, checked the machine overall, checked the homing sequence - everything looked normal. I even tried cutting the model down to 170mm square, but the same thing happened. Out of curiosity, I checked the homing probes - no problem there. I got really frustrated (I am not a patient man in any way.), and looked over every single option and setting in Cura that I could see. I rechecked the .gcode. Everything looked normal!
I am completely dumbfounded right now. I have no idea what could have caused this. I'll put some photos of the print down here in case my description wasn't... descripive enough.
Please help! I'm dyin' over here!

I just went ahead and bought some Standard Black ColorFabb filament from ToyBuilder Labs in San Jose. They offer free shipping on items over $50 (the ColorFabb was $40, sadly), and the paid shipping ($3 for me) leaves their warehouse the same day. For those looking for a California supplier - this place seems to do the trick pretty well!
-
Okay - apparently I'm doing something wrong. I went to all four websites (Faberdashery, Ultimaker, ColorFabb, and 3D Universe) and all the shipping is insane. First of all, Faberdashery is outta here - their filament comes in a pack instead of a spool. No good. Secondly, buying direct from Ultimaker costs an extra thirty bucks. Also no good. ColorFabb and 3D Universe aren't much better, either. Does anyone know of any reliable (preferably with free shipping) resellers based in the U.S.? I'm in California, so the closer to there, the better. I'll start looking.
-
Wow - thanks, everyone, for the awesome help! 22 replies already! Ok, so what I'm hearing is to get Faberdashery, Ultimaker, ColorFabb, or 3D Universe. I've had fantastic results with the standard Ultimaker filament, and I've heard great things about ColorFabb. I think I'll try some ColorFabb PLA/PHA and post the results. Hopefully, after a while, I'll be able to test out all of these filaments and compare them here. For now, I'm going for a roll of green from Fabb and see if that does any good. Fingers crossed!

Thanks for the great responses! Guess I'll put in a couple extra bucks - looks like Ultimaker or Colorfabb is the way to go. It's a shame that I've already bought 4 rolls of MakerGeeks filament... I'll just have to keep printing till I'm out, or maybe sell 'em on eBay.

Hey everyone,
After a couple months of playing around with my Ultimaker Original + (which, I have to say, is my new favorite industrial toy), I ran into some problems with the bowden tube. I was a complete idiot, and the story in a nutshell is that I squished the tube with some pliers (ruining it), and the guys at Ultimaker were so kind as to send it to me for free.
Now, since I'm waiting for the tube to arrive, I have some time to prep the machine for some more printing (buying new filament, finding cool stuff to print, etc.). Ever since that lovely roll of silver PLA ran out, I've been buying my PLA from a great company called MakerGeeks. Their MakerFIL printed pretty well, and I hardly ever ran into problems with it. And, better yet, each 1kg. spool cost ~$20, and shipping was free. But, now that I'm looking back, the prints I had were a little lack-luster in the color department. There were parts that were transparent in the sides of it where the dye they used wasn't strong enough, places where the color wasn't vibrant, all that nasty stuff. I would add some photos showing the sub-par quality, but the ones I took didn't show enough detail.
My question to you, O Great Reader, is this: Do you know of any filament suppliers that match what I've been buying? As in, the filament is great quality, low cost (under $30 for 1kg spools, preferably), and ships free? I'm looking to branch out in my great quest for the Perfect Print.
I've looked at Faberdashery, ColorFabb (their XT-Copolyester looks like a good bet), and, of course, Ultimaker, but none of them really met my standards. I might be a little picky, but hey. If I can save $20 for every kilo I buy, I'm a happy man.
Thanks for reading, and hopefully you can help me find some reliable filament!

Thanks for the replies - I'll definitely try the increased travel speed and wipe tower. However, I'm not too sure about the .1 mm layers. I really liked the sheen on the boat when I did .05 mm height - the wipe off tower sounds like a good solution for that. Do you usually just load in a separate STL for the tower, or is there a setting in Cura I'm missing? I'll do a little more research on that and post the results.

Hey everyone!
I recently tried printing the 3DBenchy torture test boat, and I think it turned out pretty well! On the front of the boat, it tackled the overhang there with no problem. I looked pretty hard to find any surface artifacts there, and, surprisingly, found absolutely zero messups. When it got to the top half of the print, however, several things (minor, albeit annoying) went wrong. I noticed that there was a ton of stringing on the walls on the top of the boat, and there were some little tiny surface artifacts on a few of the features. While this isn't the end of the world for any print, I'd like to see if anybody knows any tricks to getting rid of these little buggers.
Also, right when the print was finishing up, and it was working on the chimney of the boat, a really weird thing happened. The plastic started to drip off of the side of the chimney. It looked like some extreme overhang stringing, but the overhang it was doing was absolutely tiny. This is kind of worrying - I don't know why it happened, or if it'll happen again, but hopefully some of you know what (if anything) I'm doing wrong.
Here's the specs of the print I was doing -
100% fan
20% infill
50 micron layer height
50mm/s
No support
Used Ultimaker Silver PLA
Printed on Ultimaker Original +
Thanks for reading,

Hello,
I did something horrible when I was building my Ultimaker Original +... At around 10 PM, I was trying to assemble the heated bed on the printer (which was a terrible idea), and I was supposed to plug some connectors into the bed. I took the heated bed cable from the bag, looked at one side (without bothering looking at the other end) and pulled the plug off of the wires, thinking it was a cable protector, like a complete idiot. Now, the wire is bare, and after trying to put the ends back into the cap multiple times, one of the wires is broken. I know, it was a completely impetuous thing to do, and I was just being impatient and stupid when I did it. Now I just need to know what I should do. I went to Radioshack to try and get one of these, but they had nothing like what I needed. Is there a part list I can see, or maybe a reference to somewhere I can get this specific part? I'll attach a photo of the wires so you can see what I'm talking about.
Thanks,
-Brent
[EDIT: I decided to try and finish up some other wiring on the board while I waited for a reply, and the instructions call for 'jumpers'. After some research, I think I know what they are, but I can't find any in my kit. Is this something they removed from the kit, but not the instructions (like something in my previous post)?]
-
Oh! I can't believe I didn't think of that... I tried putting the wire in and pushing down, but it didn't work. I'll try it right now and reply again if it works.
Thanks for the help!
[EDIT: It worked perfectly! Thank you so much!!]

Hello,
This is my first post on the Ultimaker community (hi everyone!), after just receiving my Original Plus, which has been awesome to build - it was more fun, challenging, and rewarding than I ever imagined! But, after just completing the extruder, I tried to do the circuitboard, but it's only been giving me headaches.
I have the board attached to the bottom of the machine, and I have all the wires strung through the cable guides/ducts and underneath the bottom panel. It should be easy from here on out (the guide talks about how you just have to plug wires in and screw them in), but 1) the guide is AWFUL with describing this part, and 2) it's either talking about a different board than mine, or the pictures suck. It says to attach them in the part that says Heater 1 and screw it in, but there are no screws there. There are just some orange tabs that I can push down - nothing else.
Are there any screws I need to manually add into the board before doing this? The guide says nothing about this - it describes it as if there are already screws in the circuitboard.
Please help me with this - I can't wait to get printing with this awesome machine. Hopefully, after I get this figured out, the machine lives up to the $1400 bucks I paid for it!
Thanks for the help,
-Brent
[EDIT: I've already seen a topic like mine around, but the responses didn't help - I had a different board than the other people that posted. Just thought I'd start a new one!]
Infill not touching shell! Again!!
in UltiMaker 3D printers
Posted
Tried it with the tools, and the rods are all straight. Also, since I started this topic, I tried printing a pair of sandals out of woodFill, and the shell was (I measured) 3mm away from the bottom shell. I have no idea what's going on.
