    Nice mike! Do you plan to share the files for your new upper and lower supports?

    Yeah once I figure out why it keeps torque stalling I'll release them. Until then it's too buggy for someone else to struggle with.

    Where there's torque stalling, there's binding. I was thinking about using top pieces to join the rods on each side, then squaring them with a tiny turnbuckle which would also serve as a filament oiler/guide. I also want to try the self-centering z couplers I have printed out. Because they are joined with nuts, once tight they could be inset into lower z rod stabilizers like yours for a very direct connection and mechanical loctite. But I have much to do before that point.

    Replaced the warped helical couplers with some new ones. Took out the bearings.

    All seems well except some extrusion concerns.

    Started with a PLA whistle. The ball came undone and didn't whistle:

    Then I did some work on my filament storage and distribution box. Has an oil soaked sponge the filament passes through

    Then it passes through a ptfe tube to my ez struders

    Finally starting to print something for my first nephew that showed up on Saturday.

    Checked tower instead of ooze guard, woops:

    Managed to fit 2 30mm fans. Didn't think it was possible. Took some creativity and a little bit of snipping and sanding.

    Excellent!
    By the way, why do you think it needs 2 fans? Is air flow not enough?
    I upgraded my Robo to dual extruder with two E3d v6, but I can't stand the noise of the two fans.
    Therefore, I'm considering change it to 1x 40mm.

    Thank you very much!
    I'll try some idea while measuring temperature of the heatsink .

    these were fun. The ball thrower was a real pain to get inside with any sort of dual extrusion extra. I don't know why they try and place the wipe and prime tower outside the build volume.

    Mike, what if you used two of the larger fans and placed them in a push/pull configuration, similar to p/p configs for watercooling radiators.

    Yup it's a counterweight. Mostly did it at @donhuevo 's suggestion.

    There's a couple ideas at play here. The first is to see if it's possible to get my carriage autolevel working at all, though that's a small part as I doubt it will.

    Another is to improve the idler side autolevel switch and to keep the Z carriage in more of a balance. Right now the center of inertia is biased to the stepper side quite seriously.

    The final one is to act as a damper for motion. The weight will theoretically mitigate most resonance effects you'd see.

    Anyone considered liquid-cooled heat-sinks? ....6mm silicone tubing, 12V windshield-washer type pump, etc.?

    @Ziggy What pins did you plug the servo into? Did you build a FET circuit for providing the necessary power? Or would just adding a 5v supply to the line be sufficient?

    @SteveC or @Les Hall maybe you could chime in?
