This Monday, July 20, three new customers from Iran happened to visit our company. We had not anticipated that they will come. We did not get the message until last monday. Although they haven’t inquired us before.They had a very pelasure meeting with us.
The Iranian clients were here for the products as following: DIN912 hex socket cap screw; Din931 Class 8.8 hex bolt; DIN6923 / DIN6927 class 8 Hex flange nut.
(Sorry about the high pitched noise at the beginning of the video. I’m using a cheap loaner smart phone while waiting for my new phone to come in and for some reason it makes that noise when I start recording video.)
I am trying to get HIC Technology to replace this defective part and they are telling me that I assembled it incorrectly. I took this video and pictures as proof that I did not assemble it incorrectly and the part itself is defective. This 3D printer was purchased from Amazon: https://www.amazon.com/gp/product/B00N7I1ZVU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
The part itself is not square which prevents the X-axis assembly from moving up and down on the Z-axis motors and threaded rods. The ONLY way that I could get it to move smoothly up and down was to loosen the screws holding the threaded brass bushing so that it could sit square with the rest of the assembly as shown here: https://s83.photobucket.com/user/jefrom19/media/3D%20Printer/2015-02-16%2018.45.06_zpspidjult4.jpg.html.
After loosening the screws holding the brass bushing in place, I could then move the X-axis assembly all of the way down on the Z-axis, as shown in this picture: https://i83.photobucket.com/albums/j314/jefrom19/3D%20Printer/2015-02-17%2015.18.00_zpsj9zwzhzo.jpg

***UPDATE 5/3/15***
I have made several upgrades to my printer since this video was taken. To see what changes I made, look through this forum thread: https://www.502streetscene.net/forum/showthread.php?p=4053746#post4053746
