    • RE: Strange Printing Defect! Please Help,

      Jammed some paper in between the looser end on the worm gear and the bearing and it seems to have helped. I have ordered a new nimble (as they have a slightly improved version now) so maybe I need to get a replacement worm gear? I will have to measure it first and see if it was manufactured incorrectly.

      Little bit better

      @damianm reducing the extruder acceleration to 1000 did wonders to be honest. I will have to check a few other slicer settings and esteps to see if I can improve on the finish I am currently getting.

      It's good but now as good as I got from it on my previous printer.

    • RE: Strange Printing Defect! Please Help,

      Spoke quickly to Brian from Zesty Tech over email. He suggested a few things which have improved the quality but still not quite there 100%. May be having a call with him tomorrow.

      One thing I have mentioned to him though, the worm gear seems much looser in the bearing on one end, I am not sure if this is intentional but may be an issue?

      If anyone can suggest anything to improve this result further I am all ears....

      Improved

      @phaedrux diagonals, yes, circles no.

      With the nimble what could actually cause that eccentricity?

      @phaedrux extruder eccentricity? Never heard that term before? Could you give me a quick run down on it?

      Yes, I have. It's all nice and smooth it just seems a bit inconsistent when extruding. Apparently from some digging in several forums you can add 15k diff fluid as a lubricant on the nimble which apparently helps?

    • Strange Printing Defect! Please Help,

      I have built a corexy printer based on the hypercube. All gates idlers, pulleys and belts.
      I cannot get rid of this weird texture!

      I have tried upping and lowering currents, rebuilding and cleaning the hotend (v6) and liner rails, printing faster, printing slower, adjusting jerk, acceleration and max speed, calibrated the esteps a few times, changing filament, PID tuning, praying to the beard of Zues, however no luck.

    • RE: CoreXY - X-Axis Vibration Issues

      @deckingman Without a massive change to the placement of pulleys and such it's unfortunately not possible.

    • RE: CoreXY - X-Axis Vibration Issues

      @fcwilt Having a think about it, the E3D design uses the fabtotum style corexy which places the belts in front and behind the x carriage. It is technically possible to move them both behind the carriage, would that help?
