I am a new Taz 5 owner (previously owned a Robo 3D R1) and am working through some initial issues but one issue I cannot seem to figure out is z ribbing / waviness on taller prints - this seems to occur at fairly consistent intervals or layers once I start to get higher than 5-6 inches.
Everything is stock on the machine, I am using Cura with the Lulzbot HIPS filament and Lulzbot HIPS Medium quality print profile.
Layer Height - 0.25
Shell Thickness - 1.0
Print speed - 50 mm / s
Bottom/Top Thickness - 0.8
Nozzle - 240 C
Bed - 110 C
Nozzle size - 0.5
As you can see on the attached pictures the quality toward the bottom of the parts are great but then start to really worsen. The fact that it happens at these intervals is what is curious. These 2 posts were printed side by side, with 1 of the 2 having significantly worse ribbing / waviness. The table that the printer sits on has a slight wobble but I didn’t think the consistent layer issue would to contributed to the table, am I wrong in assuming that?
I have also attached the STL and gcode but like I said its not just happening with this one model, it tends to happen with everything I have tried that exceeds that 5-6 inch height threshold.
I have spent some time searching the forums and I am not sure if I have seen this or am not searching for the right criteria, so I apologize if this is covered elsewhere.
Any insight is much appreciated!
