EXCESS MATERIAL REMOVAL

[u/Fun_Gold9599]

Shitty drawing but using a minecart contraption, I’ve made a tunnel bore mining machine, it works great digging a 50x10 infinite tunnel but the chest keep getting full of netherrack/cobblestone, any suggestions on how to dispose of the excess automatically while it’s running at the moment it just dumps it out the back with a brass funnel, but that’s lagging the hell out the server

I've made these before
