I start the bot and he doesn't pay the blast furnace man, instead, he just tries to put the money in the coffer.
EDIT:
Actually, there are a few things wrong with this bot. I'm not gonna write a review as I can see it working extremely well and if you fix the bugs then that's even better, but I could only ever get a max run time of ~7 mins. Anyways I'm not trying to be mean in points below I am just trying to convey the problems I have had. Best of luck fixing them (i will upload the logs in a sec).
First off, the bot doesn't check the player's smithing level when the bot is started, thus it doesn't pay the foreman straight away if the smithing level is below 60. It will start instead by either trying to place money in the coffer, failing that sometimes it will then pay the foreman, else if there is money in the coffer, it will just run to the conveyor belt realize it can't use it then pay the foreman.
Second, the bot needs the player to have bought loads of buckets of water as it won't refill them (this happened to me twice). when it gets to the bank it will dump the empty bucket and bars in the bank then stop as there are no "buckets of water" in the bank. I personally would check to see if the player had either an empty or full bucket and proceed in a direction depending on the output.
Thirdly, I often see the bot clicking on the conveyor belt then clicking on the bar dispenser too fast, giving no time for the player to actually deposit the ore's on the belt. This is usually resolved after running it for 5+ minutes.
The fourth and final point, the bot will sometimes take ages to realize that the stamina pot effect as running out which drains your stamina very fast. I guess the check for whether the stamina effect has run out only occurs when the play is at the bank instead of everytime he stops to do something. This point is much more minor like the last point, as it will sometimes resolve itself over time.
