Finally. The Fed-Ex guy brought my ROBO today and upon opening it, the boro/heated bed was in pieces. It is completely split across the rear two mounting studs and renders the printer unusable at the moment. One corner is shattered so I would guess it got some rough treatment along the way. Further, the Z axis rods were free floating out of their sockets. Having replaced them where they apparently belong, the whole z-axis assembly is still remarkably wobbly. Achieving repeatable results would shock me with this sort of play. However, I am a NOOB - should this assembly have a vast amount of play? Also, the screw provided for the filament holder dowel is a very nice stainless unit.. a couple of sizes too large for the insert in the dowel. I have submitted an e-mail to the ROBO guys and hope to hear back soon. It is exceptionally frustrating to have waited for so long, get it, and still not be able to use it. I shall be disassembling things later today and at least take the opportunity to check, lube, tighten and cry.
