Hi,
I'm using 20x20 aluminium extrusions for my build and since it is a 3d printer, bearings won't have to support a large effort.
I was wondering how would my printer work if I use ball bearings directly in extrusion slots.
Are there any drawbacks like steel/aluminium contact reducing extrusions life span ?

I tried, berings fits perfectly, it moves quite smoothly, but in the long term ? What about effiiency ?
I need your experience
Thanks !!
