Hi, all!
Just got my refurbished Robo-3D R1+ this week, and I'm quite happy with it (as an upgrade from my Printrbot Simple Metal). It worked right out of the box, with the exception of one of the screws on the filament holder on the extruder (the ones with the screws) popping off. I screwed it back on and the printer has worked fine, however...
While I've been dialing in the settings, I've discovered that my prints are all experiencing strange gaps on some levels and I'm not sure what setting to tweak. I've tried varying temperature (starting at 210 and down to 195) and changing some retraction settings, but it hasn't really gone away.
Basically, on some slices, you can see that it has some gaps when extruding. I've seen this behavior in both MatterControl and Simplify3D. The attachepicture should illustrate it.
Any suggestions as to what would cause this sort of behavior? I've tried the filament that came with the printer and some Boots Super Premium with the same result.
Thanks!
