I’ve been using the RoBo 3D R1 3D printer for a few weeks now, printing out over a dozen models — some which came with the printer, and others created by my students using free SketchUp CAD software.
In this video, I give a brief evaluation of the printer use and quality, and a few of the (relatively minor) issues we have encountered.
UPDATE: The issues/problems shown in this video no longer exist! There are two issues that have historically caused problems on the RoBo:
(1) the Robo originally used imperial-measurement threaded rods for moving up the Z-axis… this caused improper sizing and banding/ribbing issues because there had to be a conversion to metric, which results in rounding errors; the Robo now uses metric rods, which solves the problem… BUT they hadn’t updated the firmware to reflect this change! When I updated my firware, the banding/ribbing issue disappeared.
(2) Hotend issues: the older J-head hotend would overheat, melting plastic components inside of it. They had replaced this with the newer all-metal Hexagon hotend; this one has an issue which caused the leaking I showed in this video — if you do not tighten the heating block/nozzle tight against the coldend/heat-sink while heated, it can become loose and spring a leak.
Updated review / follow-up video to come soon…
