[Diagram or photos of Print Head Assembly]

Thanks illuminarti,

I think I forgot to put one of the two screws that hold the top horizontal plate to the vertical grid back... I don't remember taking one out of there, but it was the same size as the two I removed from the bottom horizontal plate.

Your description also makes me realize that I might have put the threaded rod back in before the temp sensor was in place, thinking its only job was to keep the nozzle block from twisting.

Very helpful, thank you.

Hello,

Does anyone have an exploded view diagram or some really detailed photos of the UM2 Print Head Assembly? I just took mine apart to clean the hot end, and like a dummy, I didn't take good photos during the disassembly. Now I've got one extra screw without a home.

Thanks for your help.

 

[New Firmware Problem with Ultimaker 2?]

Yes, I'm on Cura 14.03. It seems to be working fine, but I think there was an initial glitch when I updated the firmware. I'm about to give everything another go.

update: I did a factory reset and the problem was resolved. I guess these things are bit like apple computers where most of the time a restart will solve the issue.

Hi IRobertI,

I assume you mean pressing the click wheel before the filament reaches the first clip on the bowden tube? I've tried pressing the button the minute the feeder grabs hold of the filament, and it still feeds for much too long.

 

[New Firmware Problem with Ultimaker 2?]

Hello everyone,

Upon launching Cura today I was prompted to download the newest version of the software, along with a Firmware update. After doing so, I can't successfully load new material into the Ultimaker 2. The issue, specifically, is that the feeder is overfeeding the filament. Back in the good old days (yesterday), the "change filament" routine worked beautifully: you'd hand thread the filament into the feeder until it grabbed hold, wait until the filament reached the first clip on the bowden tube, and then press the click wheel to speedily advance the filament toward the hot end. Just before reaching the hot end the feeder would slow down. That is no longer the case, as the feeder continues advancing the filament at a high rate of speed for a second or two too long, slamming the filament into the hot end, failing to extrude, and then grinding down the filament to a state where it can't be further fed toward the hot end.

Is anyone else experiencing this?

Thanks ahead of time for your help and suggestions.

 

[Contraction in diameter when printing cylinders]

That makes sense, I'll give it a shot. Thanks for the help.

 

[Contraction in diameter when printing cylinders]

Hi everyone. I've had my Ultimaker 2 for over a month now, but am just now pulling myself away from it long enough to join the users group. In general, I have to say that I'm very happy with the machine.

I have noticed an interesting phenomena on the lower portion of some of my prints and wonder if anyone has any suggestions as to what might be going on. When printing cylindrical forms a contraction occurs in the diameter of the cylinder at just about a 1/4" above the build plate (.1 layer height) and lower when printing at thinner layer heights. This is the case with both PLA and ABS.

Here are some pictures, I hope they load correctly (I'm new at this):

 

 

Any feedback would be greatly appreciated.
