Thats funny, i got that one and it keeps clicing the bars on the furnace 1 by one which takes it 8times longer. It should press x and enter the amount to smelt. Whats wrong with mine? This is for cannonballs btw.
EDIT:sorry i dont got that one, some stupid mistake, i got autosmelter CS, it doesnt do most other bars very well either. The bot has difficulty switching to banking script after it has molten the amount of bars. Also it cant detect the furnace most of the time so it keeps walking a few tiles up and down and then it logs off after 2 minutes because the green button turned red. So simply, it failed. Also it pisses me it only supports al kharid and falador. Are there scripts that support port pasmathys, cause i would really prefer a bot that works over there. Very less people there also. Almost the summit point of low crowded places and certainly no mods there.
