Hi, I try to order Ultimaker 2. But I find no filament color option like ordering UM Original before. Does anyone know if there is one free reel of filament coming with UM2? May I choose the color? I got the spec. sheet of UM2 and UM Original. But I don't understand what is "In build display" and "direct drive". Where I can find the description about them? Thank you.

@gr5 As Nicolinux says, I don't understand how to firmly tighten the z nut, either. Would you show us the video or pictures?

Thank you for all the enthusiasm and kindness. @SandervG Sorry for my ignorance. The 2nd picture link about platform is supposed to be this? I'm not sure if on filament are clear enough... I tried to heat up the extruder to 250 degrees and the PLA filament flow went smoothly. So the surface problem may be caused by Z stage. @gr5 and @Nicolinux So....is it default setting and no need to adjust? I guess it caused by z stage. Here is the at 0:58~1:00.I want to make prints look more delicate. That's why I usually print with 0.06mm layer thickness. I thought the thinner layer the result better before I print out this here besides crack issue.

Hello guys , I'm a new comer to this forum. There some issues I didn't get clear replies from the support team of Ultimaker, so I come here. I suppose here must be someone who can help me. 1. These are coming with Ultimaker, and the support team told me they are tools for X,Y axis calibration. I don't know how to use it. Could anybody show me how to use them? http://imageshack.us/photo/my-images/20/rmso.jpg/ 2. How to calibrate the printing boundary? It is the result after I run the leveling wizard on a desktop pc. How can I move the print range back to the middle of the platform? http://imageshack.us/photo/my-images/20/rmso.jpg/ 3. I'm troubled by more and more prints getting the issue of layer marks and sandpits like pictures below. They are printed with PLA, layer thickeness 0.06mm, fill density 5 or 8%, print and retraction speed at 50 mm/s, feed rate 100%. http://imageshack.us/photo/my-images/820/tsbg.jpg/ http://imageshack.us/photo/my-images/842/7azc.jpg/
