    Seeking instructions from people using Creality Print 5.1 slicer

    I have been trying the Creality Print 5.1 slicer on my Ender 3 V3 KE printer. So far, I am unable to use "Tree (manual)" option under Support. I can't find a way to "manually" apply Tree support on the area I select. Any input is appreciated. Thank you.

    Why gps drones do not do 360 degree flips?

    My personal preferences of a drone are as follow...... 1. Being able to do 360 degree flips. ( No fun if a drone cannot flip.) 2. Being able to stay put in mid air steadily when I'm "hands off " from the controller. I can have a drone with both optical flow positioning that allows the drone to...

    Maybe I shall get to know how to fly fpv after all..... maybe

    A few years ago I tried to fly fpv and failed miserably. I crashed one to pieces and lost another one to nether land. And I quit. Conceding that at my senior years, my reflex and hands-eyes-coordination are no longer reliable. 3 months ago, I came across an info about a Cetus drone equipped with...

    Can a $25 CAD indoor mini drone be that much fun?

    You bet!! I have more fun flying it indoor than flying one of those powerful brushless drones outdoor. Tiny but packs with lots of fun. It costs only $25 Cad ($29.99 less $5 coupon). It flies with REAL Altitude Hold. I mean it really does Altitude Hold. It does 3D flips. My favorite among drone...

    A crazy thought from an 81 yrs. old man

    I have had a 5 in x 6 in calculator for over 5 years, at least. It is solar powered. No need to plug in for charging. Never out of "juice". Always performs correctly. Now, why can't we have solar power computer keyboard? That way, we never have to worry about replacing batteries or plugging...

    fpv goggle for toy drones?

    Hobby drones have the luxury of having goggles to enhance the pleasures of drone flight. Toy drones do not appear to have such privilege. My question : Is there any goggle available for toy drones? Or do we, the toy drone users, have to settle for VR goggle?
