Belts or Ball Screws???

Hello everyone

I Am sure this as been asked before but i could not really find anything

I have built a bunch of cnc mills, routers, lathes etc..
I am pretty sure i have enough junk to make my self a
3D printer, I looked around for ideas and i see pretty much
Everyone uses a belt for X and Y axes

Is there is special reason for that ???

Is it for speed ??? I have no problem getting 400 500 inch per minute
(10160 12700 millimetres / minute ) With a ball screws
I know them little stepper drivers probably won't cut it at them speeds
I have some gecko drives i can use, i have a couple Of ramps boards
With marlin, i did not really get a chance to really play with it yet
Is it marlin that would be the problem????

Thanks
Biggs

... low forces/masses and higher max. speed with belts ... much higher forces/masses, but much slower too then, with ball screws ...

Hi thanks Viktor

Thats what I figured, but I imagine a extruder and hot end would not be able
To keep up with 400 500 inch per minute??

... I was experimenting with FDM-printing on my old CNC-mill with even higer speeds (30mm/s), what's pretty slow, compared to good adjusted common printers, which are capable of printing speeds with up to 200mm/s! (my own tests without printing were wit up to 400mm/s and have two old Janome dispensers which were run with up to 800mm/s!!).

So ball-screws, compared to belts, are very, very (boring) slow
