I cannot enter my UM2 serial number in the app because it launches the camera app and I don't have a bar code anywhere on my machine or the box it came in. Instead I have a serial number sticker on the bottom with a number that says "made in the Netherlands". On the box I have a shipping label but no serial number. I don't see any options to type the serial number in.

Thanks for the link to the topic. Fixed the error messages by properly seating the temp sensor and heater cartridge when I replaced my hot end. Back on 15.01 with no issues today - so far.

Mine is obviously out of spec based on the photos in the assembly manual. Thanks. I will have to replace this hot end with the new one that fits correctly.

The heater sticks out of the block on my UM2 by several millimeters. It just won't go in any further but the temp sensor is all the way in. Both seem to want to slide right out as well when the machine runs - there is no real friction holding them in. Any suggestions on how to get them to stay in the block - some kind of adhesive maybe ? Is it standard for the heater to stick out of the block a little bit ? I have a new hot end that i just received and if I test fit the heater into this block it still doesn't go in completely. There is metal sticking out and the heater does not appear to be warped or swollen in any way. Suggestions ?

I have a stock machine. Does that mean I really have a 'heater error' of some kind? It would be a shame not to be able to take advantage of newer features. I was running default profile slicing values when this happened with no modification to the PLA profile on the machine. My fans are quite robust and loud when they run.

I'm not sure what's going on with 15.01. I've updated to this version this morning along with the firmware but have experienced issues all day today of one kind or another. The biggest so far is a 'heater error - contact ultimaker support' error message I've received several times which stops the print head cold while the machine endlessly extrudes filament. I was able to print a couple items no problem but had to stop twice and reset on 2 different files because of the same error. The only correlation I noticed was I ran the 'change material' function each time before the error. I've rolled back to my previous version of cura 14.09 along with the firmware and so far no error messages. I'll update if it's just my machine but so far it looks like not. Mac OS X -> Ultimaker 2

Ya I guess the profiles save option is probably for slicing and not for the machines.

Awesome. Thanks! Makes more sense now. I'll play around with it. :cool:

I see some machine profiles if you right click on the cura app (MAC) and choose show package contents. Also I see that you can save the profiles from the main menu bar. Best to have a backup copy of those saved. So at worst you could just restore cura from Time Machine, open it up and save your profiles.

Nothing happened when I clicked the button. I did change the path to my SD card and that seemed to work. The path was pointing to my user folder. So the path is set to a single instance of one of my SD cards. I'll have to try to figure out what this 'replication' means I guess.

I've just installed cura 15.01 on mac os x 10.10.2. I noticed the program recognizes the SD card but the icon that you would normally click to do a quick save to the SD doesn't do anything. Just wondering if it's just me. I can always use the save GCode function so it's not a huge deal. :-)

1. ABS can be printed in high quality on the UM2. I found it a bit more tricky to get the print to stick, but once you get the settings locked in, it does well. I prefer the PLA results. 2. The UM2 does not print flexible filament well. I haven't tried a wide array, but the one's I've tried have failed due to the bowden type extruder setup. Some people have had success printing at very low speeds with this type of filament. 3. The disadvantage of 3mm filament is finding a good filament that actually will fit through the extruder. 2.85mm is the actual size needed and most generic 3mm filament just doesn't cut it. You'll need to stick with the higher quality stuff.

I haven't had much luck myself with the 'spiralize' option. However, you can make the infill 0% and then in the expert settings uncheck the 'solid infill top' and make sure you check 'solid infill bottom'. I haven't printed a vase in a few on my UM, but this is how I've done it in the past when the actual model is a solid object and I want a vase.

You should post your exact printing specs so others can suggest improvements. Temp and speed play an important role along with other settings.
