Finally, along comes the Lulzbot TAZ4.
-After just a few days it may be a bit much to say “Lulzbot rescued 3D printing for us”, but that’s about what it feels like right now.

-It has a large print area and is capable of very fine and precise prints. It follows all best-practices I’ve ever read about making 3D printers. E.g. it has a heated glass-surface which is perfect for PLA. Beyond that, you might even accuse Lulzbot of over-engineering. Looking at the industrial grade cable connectors, screws, bearings and shaft couplings, you know they didn’t skimp on the parts. Next to that is ships with a bag of quality tools which even includes a jar for mixing ABS and Acetone.<figure style="width: 414px;" class="wp-caption alignright">

All in all, the printer gives manages be at once a highly professional machine as well as a matured hackable open source project.
-Of course, it would not be bitchy us, if we didn’t find anything that could be improved. Most of that can be traced to the firmware: The sampling of the rotary encoder for once feels sluggish and imprecise even though the encoder itself is high-quality. We also wonder if the forces reset on sd-card change and usb-cable plugin is really necessary. Finally, it’s OK that the printer does not print from SDcard when still connected by USB, but it could display a warning instead of just plainly doing nothing after one selects “start”. Also the resonance frequencies of the printer could have been measured and the firmware modified so it would then avoid certain of those speeds and direction changes. Since it’s all just software, we may actually do something about that in the future <img class="icon" src="//realraum.at/wiki/lib/images/smileys/icon_smile.gif" alt=":-)" />On the hardware side, we noticed that the power supply’s cooling fan would still run long (hours) after the printer had been switched off. (Note: the only big off switch is on the DC voltage side of the printer). Not sure if that fan actually ever stops.

-All that (and on the bitchy side: the fact that it’s just that) really really shows just how much experience and know-how (hard won over the years of DIY 3D printing I’m sure) went into making the TAZ 3D Printer. Thanks #LuzlBot !!<figure style="width: 445px;" class="wp-caption alignleft">
