  • My fleet of ender 3’s have upgraded themselves all to direct drive linear rail dual z, etc. but they’ve also been instrumental in creating dummy and temp parts to build multiple CNC machines, which then are used to make their own final parts. It’s wild what you can do!

    I’m currently rebuilding a brand new AnyCubic Kobra2 max, since the factory controller hardware is trash. I bought it for the frame and hotbed. It’s getting all new motion control, klipper, direct drive, bl touch, and a input shaping among other things.








  • If this is new, think you have a wheel adjusted too tight. When this happens, during rest it develops a small flat spot which translates to mechanical ringing in the print. If you let the machine sit for a while, then slowly move that axis, do you feel a bump where it was at rest? All of the axes should be smooth with no felt noise. If you feel noise, you’ll see it in prints.

    If not, I would inspect your axis rails for any contaminants or damage, I used one of my printers so much I wore out the actual aluminum extrusion on the y axis and the bed was developing mechanical slop, which was actually difficult to find until I checked the bearing races.
