I’ve owned an Ultimaker 2+ Extended for about a year. When business got busy enough to necessitate a second printer I decided to try a Taz 6 based on it’s overwhelmingly positive reviews and larger X/Y print area dimensions. I’ve owned it for 4 months now and it has been a near constant disappointment despite all troubleshooting and diagnostic checks indicating it is functioning properly in every way. In my experience (and perhaps specific to the kind of work I do) there has been nothing the Taz has done better than the Ultimaker and surprisingly few things it has even done as well. I have relied on the knowledge base within this forum to troubleshoot through some of the issues I’ve had (thank you all) and I’ve made some of the common modifications that help to enable the printer to do what it should have been engineered to do out of the box. Sadly it is still infinitely finicky and unreliable as compared to the bone stock Ultimaker.
As I said, I understand this may be specific to the kind of work I am doing with the two printers and I’m not here to hate on the Taz 6 but at this point I am thoroughly fed up with it and wish very badly I had two Ultimakers instead.
