Hi all,
I’m getting a weird stepping-like anomaly in my prints, but only at the end (around the 80% mark). Otherwise, my Taz Pro prints beautifully. I’ve included a picture of two different prints that are printed with a 90 degree difference. It seems to be something related to the Y-axis?
Everything seems to be calibrated correctly. The tension on both the X and Y axes seems good, and the pulleys driving the belts seem fine. The plate isn’t hitting anything during printing. Any ideas?
At that height, there’s a good chance the motion of the bed is causing the model to tip slightly, which is catching the nozzle, preventing movement of the bed or toolhead, and causing a layer shift.
This is especially noticeable when you’re using grid infill, which causes the nozzle to cross extruded filament on the same layer. And when it’s a large, heavier print, the extra strain on the Y axis motor from weight, plus snagging grid infill, and a little sway in the part, and this is what you get.
I would recommend using aligned rectilinear as your default infill. If your parts are functional parts that need strength, gyroid is great as well.
I can’t thank you enough, Wrathernaut! I switched from Grid to aligned rectilinear (line), and there are no more stepping issues in my print at the very end! I also noticed that the small screw tightening the front Y axis bearings needed a little adjustment, which was probably contributing to the issue you mentioned. My last print came out perfect! I’ve gone through so much plastic trying to get this one part to work, so the planet thanks you too! : )
