New Taz 5 owner here, nice to meet you all. I received my Taz 5 a few days ago and wanted to share some concerns with the unboxing, just in case it might help some others.
First and foremost after spending time setting up and tuning the printer, I am in love. It is fast, solid, and produces wonderful prints. It will be replacing my RepRapPro multicolor as my primary printer and so far it is doing that job very well.
For the unboxing, the printer was packed very well, and arrived without any damage to the packing materials. Most of the issues I experienced seem to be related to the factory assembly and testing of the machine. I suspect Lulzbot has a large demand for the new Taz 5 and might be a little overwhelmed.
#1 - One of the glass bed holders was badly bent, and made it impossible to level the bed. I had to print a replacement holder on my older printer. Once I print the replacement leveling the bed was easy. The fact that this made the bed unlevelable surprised me as the bed is supposedly leveled at the factory for the test print, there is no way the printer would have passed that test.
#2 - The X-axis belt pinion was very loose. The pinion would freely rotate 10 degrees on the shaft. This also would not have allowed the test print to succeed. I tightened the pinion allen screws and had no further issues with this.
#3 - The left Z-axis lead screw nut was bound so tight the motor would miss 3/4 of its steps. This was the biggest issue. In reviewing the forum, this seems to be a common issue and customer support recommends loosening some of the lead screw mounting screws to remove the binding. I did not want loose screws on my new printer so instead I used brass shim material to create a 0.1" shim for the back side of the lead screw mount. This removed all binding and allowed all screws to remain tight.
What concerns me most about this is that with these issues there should have been no way for the test print to have completed, so I am wondering if the octopus that was shipped with my printer really came from my printer?
I knew that the Taz was focused towards the more advanced group of users and that I would be taking it apart to upgrade it at some point, but still I expected the full product to have had a little more QC on it before going out the door, not just checking the boxes on the included QC sheet.
In summary, I love my Taz. It is a first class 3D printer and I would recommend it to anyone. Also Lulzbot has first class support and a huge helpful user base that also makes it easy to recommend to anyone. But had I been a more novice user, I might have returned the printer fearing the quality based on my unboxing experience.
Lulzbot - Keep up the great work and thanks for the awesome printer!
