Ok so this review covers two transactions; the print head most recently ordered, all is well, pretty standard exchange... and the previous one wherein I acquired an entire Lulzbot Workhorse setup. I didn't follow through at the time with a review as life went...sideways for a while, so this gives me an opportunity to pick that ball back up again. The PYM3D team went well and truly above and beyond with that printer purchase, straightening out payment for me, watching out for me when I assumed the Taz6 enclosure would fit and correcting on my behalf to the not-yet-at-the-time-released Workhorse enclosure. I appreciate it greatly despite not mentioning it at the time.
The gear itself, of course, is top notch. All Lulzbot equipment I've used has proven to be well worth the investment, if not more so.
All-in-all: Thanks very much!

I have recently received Lulzbot new M175 Tool Head which I purchased from Printyourmind3D. First,all the purchases I have made through them has been without problems. They are more then ready to help you at almost any time of day. Purchasing from Printyourmind3D is so straight forward.They take care of everything. One price covers everything.
The new Lulzbot M175 Tool Head replaces the original 285 head on my Taz Workhorse. The installation was a breeze and the firmware update does everything automatically. No need to worry about esteps/mm. I now print everything using the more popular 175 filament. 2 days of printing at recommended setting using PLA and not one failures. Also no stringing which is great.
