RetromanIE

I've got a UM2+E, no interest in the UM3 so I'm hoping there's something to pull me in to this new one other than dual extrusion.

So a quick update. I fixed up my feeder at the back but still have the same issue. No big deal as i just need some minor parts i reckon.

Thanks, But I've already replaced with a fresh 0.4mm nozzle. I can say after looking at that link tinkergnome shared that my feeder is not setup as it should. So I'll fix that up when home and see if it makes a difference. It's probably a combination of the feeder and coupler, or at least i hope so as they are easy fixes.

Hmm, pretty sure the top of my screw is in the area I've marked in red.

I have some under extrusion issues at the moment on my Ultimaker 2+ Extended. I'm getting the usual weak prints(they look externally fine, but break/bend easier than they should) and walls are not touching on my test 20mm cubes. If i increase the temp to 230-235 and flow to 125% the prints are fine(this is standard PLA with 0.2mm layers). I'm using S3D, but get the same results with Cura 3. My extrusion width is set to manual and 0.4mm to match my 0.4mm nozzle. If i change it to auto or manually increase to 0.48mm or reduce to 0.35mm as it is in Cura i get the same results more or less. I plan to service the printer soon, so my question is what parts do i need to replace? I'm thinking I'll get a new bowden tube and TFN PTFE Coupler(I think this is the main issue i have right now) from 3DSolex. The only other thing i can think of is the feeder is not pushing enough plastic in. The white plastic tension tab is all the way up the top and my understanding is it should be in the middle. But perhaps this is for the older UM2 feeder? Turning the top screw doesnt seem to change anything on it, it always stays on the top. The feeder is holding the plastic filament quite tightly, so its not slipping or anything when printing. Any advice or direction is greatly appreciated.

The "Ironing" option is interesting. Tested it on a cube and 60 percent of the top was very nice, but the rest had lumps where it looked like the nozzle stopped briefly and some plastic extruded. I wasn't watching it finish so not sure what happened. But the 60 percent of the top layer that was smooth, was super nice indeed

I don't think it's still in warranty actually. It was a UM2E that I upgraded to a UM2E+. So i better go find some parts

I was having some issues on one of my Ultimakers (UM2E+). I was getting some banding on prints in the Z axis. No big deal as I can troubleshoot that and resolve it, or so i thought. The Z axis screw is actual bent a tiny bit(I think it always was to be honest), but the main issue is the Z axis motor, it has problems moving from time to time. It can cause failed prints as you can imagine at intermittent intervals. I really only noticed that issue when I was raising the bed and it stopped halfway and started clicking and grinding the other day(also a slight electrical burning smell from it, you know the one). Seems to happen randomly but in general the print quality is now rubbish as the Z axis is just not performing as it should. I swapped the motor into another Ultimaker 2 Extended + we had spare in the office, and the issue follows the motor. Also compared the lead screw and isn't quite as straight as the other working printer. While i was at it i swapped the good parts into the "faulty" Ultimaker and did a test print, all went fine. So, where can i get a new motor and screw? Warranty replacement or do i just buy the parts? I see I can no longer purchase direct from Ultimaker and the parts are not for sale by resellers I dont think. Any help, guidance or direction is very much appreciated, especially the official line from Ultimaker .

Polywood is easy to print, i like it Polywood @ 0.1mm layer height: Polywood after 30 seconds acetone vapour treatment:

I've got some Misumi LMUW6 linear bearings coming next week. So will replace the standard ones in there with these. It won't fix everything but they are a nice upgrade anyway. Although I think LMUW6 is technical linear bushings? Any experts here on that?

It'd be very handy to get 0.2mm, 1mm, 1.5mm and 2mm nozzles added to the drop down menu. I know we can mess with line width etc, but a drop down is nice

Can i just tighten them? Or is there more to it?

Heres a quick video with me moving the print head around. It moves ok, not butter smooth though. You can also hear the 8mm shafts moving a bit. Apologies for the background noise, thats two Trinus printers working away behind me

So I removed the belt tensioner and did all of the above. Still the same sound. The axis that pulley sits on does have a few mm of play, and has done for a while. By axis I mean the bars that also can be seen/moved from the outside of the printer(well, the ends of them can be seen and pushed). Should they be locked in?

Thanks, will give that a try and report back.

Does anyone have any idea what might be causing the creaking noise in the video? It's not affecting print quality, not scraping off the printed parts, I can't see anything rubbing and its not the feeder. Everything is lubricated well. I've looked at everything and just cant track down exactly where the sound is coming from, but it does seem to be towards the back right hand side of the printer. All screws are tight, as are the long ones in the print head. Could it be a problem with s stepper motor? It's not the normal sound you hear when a stepper is faulty or starting to fail. Any help is appreciated folks You can really hear the creaking towards the end of the video.

So I only have the option for 0.25, 0.4, 0.6 and 0.8mm nozzle options in Cura. How can I choose 0.5 or 1.0 etc? I have an Ultimaker 2 Extended +. I must be missing something obvious

The project file is in that link. I dont see an option to attach files to posts here(just images and such).

I've added the gcode and project to the below link. I should mention I'm using tinkergnomes latest firmware (17.02.1). https://drive.google.com/drive/folders/0B69DctF0Bt9BamZsTzlqdDBTR3c?usp=sharing Thanks

I'm running the latest version of Cura (2.4, not beta) and am having a weird issue when using vase mode. It seems to be doing a zhop type movement every layer, but is actually running in vase mode. You can see what I'm talking about in the video. Anyone have any idea what setting might be enabled, or is it a bug. I'm using a 0.8mm nozzle on my Ultimaker 2 Extended +.

So I normally use custom profiles in Cura for my Ultimaker 2 Extended +. But today I noticed that all the default (fast/normal/high) profiles have a fan setting of 50 percent for PLA. Is this the new recommended setting(I normally use 100 percent)? Or just a bug? I would imagine 50 percent wouldn't be enough! If someone can clear it up for me that would be great.

I generally use Dimafix on the glass bed. So yes i guess it doesn't really matter I was just curious, sometimes i want a really smooth bottom finish on a print, and clean glass really helps with that.

So I just got another glass bed for my Ultimaker 2 Extended +. This might seem like a silly thing to ask, but can someone confirm its the side with heat/hot sticker on it that we print on? My understanding is that both sides are not the same and there is one proper side with a coating we should always use.

Someone called? Let us know how the printing goes (pictures are always nice ). If you still prefer a sticker, let me know and I'll see if we have some lying around somewhere! I'd really prefer the stickers to be honest SandervG, can you sort me out? I did print out a "+" using the smaller nozzle, it looks ok-ish, but not as clean as the sticker.
