    Look at the inverse of the square root function, f(x)=x² (https://www.desmos.com/calculator/2v5gzbhru8)

    You can get the sqrt of a given y by looking at the x axis. E.g. the value of y=4 has two solutions, x=2 and x=-2. This however does not mean that the sqrt of -4 is also 2! If you look at graph you can see that there are no solutions for y less than 0.

    sqrt(-1) , sqrt(-2) (i ill omit imaginary numbers here) and so on do not have a solution. There is nothing you can replace with such that x × x is < 0 because multiplying two negatives always nets a positive.














  • I just got a Bambu A1 this Tuesday and have been printing non-stop during the workday.

    Made some Planters, Box for the Hotends, Poop Chute… No issues so far.

    And setup was pretty easy. No need to tinker around. It just works. WiFi Setup was a bit finicky (it wants 2.4GHz and the length of the SSID seems to be restricted?)

    But yeah… friend of mine summarised it perfects:

    if your hobby is printing, get a Bambu A1; if it’s printers, get something like an Ender
