  1. Thanks for the suggestions Mr. Waldorf. I guess I'm worried about the cable putting angular stress on the printer bed. Although it seems like that isn't much of an issue. I might still remove the entire chain because it worked properly before I started messing around with it.

    Edit: I'm please to report that after a few torture tests, my prints seem to be unaffected (knock on wood) and the chain stays.

     

  2. I love the design and look Robert, it was such a huge hassle to properly mount, I'm not looking forward to removing it.

    Its a shame. :(

    Edit: I took one more link off (down to seven not including tips) and it seems like that took some stress off the cable. Its currently printing (I took it off while printing the mm3/s test) so I can't tell if there is less stress on the cable in the resting (bed down) position. I think this should enable me to keep the cable chain. I hope...

     

  3. I printed out |Robert|'s cable chain. Per "instructions" I printed 12 segments not including the end pieces. My final assembly I had to remove four segments in order to get it to properly fit, and the bottom segment doesn't have enough slack to be secured (double sided tape) to the bottom of the Ultimaker2

    So far it doesn't seem to be interfering with the prints, but I wanted to make sure that I'm not doing long term damage (I don't even know how this would do that). The cable doesn't seem to be interfering with any critical operations, but I'm worried mostly about putting stress on the connectors to the bed and board. Is this a concern? They don't seem too tight...

  4. I find that the setting for "Print all at once" vs "Print one at a time" is wishy washy on my computer. Sometimes it prints them all at once, sometimes one at a time. The only way I know is if I check the layer view. Changing the setting to all or one doesn't change anything.

     

  5. I was dreading doing this test, here are my results from two tests.

    I got the Ultimaker in the mail late last week. I replaced the stock filament guide with one designed by Geeks. I disassembled my feeder mechanism, re-mounted the feeder stepper (in its stock location) and reassembled the feeder without making any changes. I played with the feeder tension a little afterwards and left it a bit looser than when it arrived.

    Print 2:

    Before I started print two, I unwound my filament from the spool. Then I rewound it to make sure I got rid of any tangles. I was getting towards the last 1/4 of the spool so the filament was wound really tight.

    As you can see, lighting makes a difference in spotting defects in the prints. The reason I did the second calibration print is because my print immediately prior to it at .25mm layer height and 100mm/s speed had constant under extrusion at 210c.

    Should I print this material at 230c going forward?

     

  6. One last thing . I think it's like Marlin . At startup the wire is not sufficiently present in the nozzle , this is due to the end of the previous printing . It is therefore necessary to nourish hand with the "move material" . Must be thought of talking to Daid for it to be taken into account in the next version.

     

    This has been driving me crazy! Luckily I print everything with brim, so if I forget, I'll lose one row of brim at the most.

    When do you plan on publishing your V2 feeder design? I have all the parts for you V1 printed and ready (waiting for my threaded linear rod to show up). I'd rather just jump right into V2 if its working better for you.

    Ian, you're doing a fantastic job and inspiring a lot of people! I can't thank you enough.

     

  7. Since Robert is too modest to advertise his own designs, I'd suggest checking out the https://www.youmagine.com/designs/low-friction-um2-spoolholder

    I also installed a https://www.youmagine.com/designs/filament-guide.

    If tension on the filament or friction from the spool was causing your issues, then these two items should help. I'm still printing the spool holder (and need to wait for my bearing to show up from eBay) but already have the filament guide installed. I noticed an improvement after installing the filament guide, but I also slowed down my general printing speed just to be safe.

     

  8. i wonder what the magic number is ??

    I mean.. if you had orders just an ultimaker 2 without filament or anything else.. would that allow your printer to fly under the tax ?

    I guess you would have to ask DHL ?

    Ian :smile:

     

    I'll let you know when I get mine, my order is a U2 without any extra adds. I wanted to order extra filament but decided that it might bump me into extra customs charges territory, its a shame it has to work this way.
