  1. 4 days..... sounds much better, I sent the letter on 1/23 and will wait and see if they got back today:-)

    On the assembly manual, it says my part is PT-100, but I don't know if there is any difference between PT-100 and PT-100B. And I'll try to clamp it to see if it works first.

    Thanks.

     

  2. Like in my previous post said, I broke the PT-100 heater sensor because I snapped it too hard, so I ordered the replacement for the part. However, I ordered Thermocouple Sensor because on the page it says PT-100B is only for UM2 and mine is UMO+.

    Now I received the part, but found the part is not what I am looking for and wondering I should order PT-100B instead. Can I know which part should be used?

    Also, already sent letter to customer support, but based on experience it should take them 2 or 3 weeks to reply. Can I just send it back for refund while placing new order at the same time to save some time?

     

  3. I got the same problem last week just after finishing the assembly. I don't know if I was right since I am just newbie to this printer.

    I noticed that even the bolt v.s. screw were tightened, if you spin the gear backward, it will unscrew the screw. So then I tighten everything, remember to put the black plastic into the gap, and then don't dial back the gear even a little bit. You should be fine for printing.

     

  4. Hi,

    Was disassembling the hot end to tighten everything for leakage problem, everything goes well but in the end I pulled out the PT 100 with pliers which is still hot due to the warmed hot end. The PVC covering then dissolved and then fell off.... too bad.

    Can I know may I fix it with anything or can only order one from Ultimaker? Also, the PT 100 for my UMO+ is the same as the Thermocouple Sensor?

    Thanks.

     

     

  5. Now having done 4 piece of flex PLA print, and found the only way to take the print out easily is changing the position of the print to prevent too much solid area stuck on the bed. For example, don't lie the print on the bed totally, flip it up on one side with 30 degree slope angle and remember to print support, then both the printing quality and pulling out effort would be improved greatly.

     

  6. Hi,

    I am trying my first Flexible PLA with UMO+ heated bed. The print finished well but it just stuck onto the heated bed firmly. I then pulled with force and the print just broke from the bottom layer and the bottom still stuck on the bed now. Can I know how to get such material off? No heating the bed will help?

    Thanks.

     

  7. Hi,

    Just finished assembly of UMO+ and started testing for a few days. For every print, there would always got some black burnt mark on somewhere of the print out. Sometimes there is only some blacks, but sometimes you can see it really kind of burnt and dissolved. Can I know how to solve this? Is it because the bottom layer doesn't stick to the bed so the prints got uneven base and swing a little bit then the nozzle touches the print? Any suggestion would be appreciated.

    Also, can suggestion for the proper temperature for PLA to be stuck on the bed better?

    One more stupid question, how to remove the material? I dialed back the feeder gear but it didn't work.

    Thanks.

  8. Hi,

    I finished the assembly yesterday and headed into test run directly. So I tried to fill the filament into the feeder and this is my First time! I put the filament in the tube and spin the gear to reel it in. But the cap nut then fell off. So I thought the hobbed bolt should go deeper to the cap nut.

    When it went deeper to the cap nut, the neck of the hobbed bolt kind of disappear and it became difficult for the delrin clip to hook on it. I put too much force and the clip just broke.

    Without the delrin clip, I continued test run but the outcomes are bad. The material doesn't feed well that in the middle of printing the material just didn't come out for about 10 layers and then the material came out later.

    1. Can I know if this is because I didn't use the delrin clip? or other problems cause it?

    2. Also got a question here for the hobbed bolt, do I need to insert it into the nut all the way, or just insert it in middle? but if in the middle, the cap nut will fall out easily while feeding?

    3. Can I know if the drawing of the delrin clip is available? Thought I can make one with my UMO+ but can't find it.

    Thanks.

  9. Hi,

    Now finally finished the assembly:-) But got question making the final adjustment on the Z stop switch:

    It says adjust the height of the z switch until hearing the "click", does it mean the height has to be exactly where it clicks? Or, after the switch clicks, it still should go up a little bit till the switch close fully?

    Also, for the heated bed alignment, can I buy a horizontal lever and put it on the bed directly? won't this be easier and more accurate?

    Thanks.
