Bests & Worsts Reviews from Amazon

I hardly ever write reviews on Amazon, but I feel the consumer needs to be aware of a Lulzbot product defect. I received my Taz6 on August 15, 2016. The printer was unboxed and I ran the test print which came out just fine. I then started printing different items for the next 6 weeks without any issues. Then the other night an awful sound starting coming from the Z-Axis and the printer would not calibrate. I thought it may be a fluke, so tried again and the printer started right up. I went to check on my print after a few minutes and saw the Z-Axis failed and drove the extruder into the heat bed. This caused a huge bubble right in the center of the heat bed. I contacted Lulzbot customer service via phone and spoke to a very rude gentleman. He informed me that the Z-Axis just need manually adjusted and it would be just fine and hung up. He could have cared less about the issue. I then sent pics and videos to the Lulzbot tech email and after communicating back and forth they came to the conclusion that the heat sink has failed on the Z-Axis. Here is the exact text from his email stating that the heatsinks are faulty. Text from service rep "The reason being is that we've tested the cooling properties of the heatsink and found that it does not provide adequate cooling in the larger control box on the TAZ 6 (it was required in previous models but the TAZ 6 has much better cooling inside the control box) and actually traps heat, and secondly we've had a recent run of heatsinks with faulty adhesive making it a double-edged sword. We actually no longer install them in production of TAZ 6 for these reasons" Since the heatsink failed this is causing the driver to go bad and let's not forget this printer in only 6 weeks old. Now, I have to ship the printer back. I bought this printer to start a business and things need to be printed for customers this week. I would have thought Lulzbot would have their act together since this is there 6th rendition of the printer. Plus, at a price tag of $2,500 you would expect a higher standard of quality, not the quality of a cheap cloned knockoff. Lastly, this is not a one-off incident. Other people have written reviews of the heatsink failing on the Z axis. I know my recommendation probably means nothing to anybody but I would strongly advise not to purchase from Lulzbot.
