Mine does the dismount, drop slayer in pack beetle, remount thing.
I run it in a loop. I craft "last item" so you have to make one before starting macro (and smelt it). After its crafted I use an If statement looking for "You have successfully". If I made a slayer, I dismount, place slayer in pack beetle (using an organizer) then remount. If I don't make a slayer, I smelt weapon and move ingots to a trapped box (using a different organizer) to prevent theft. Then it loops. I had to ad in a few waits to make it work right but seems to be running well nowdo you start the macro after if says youve created a slayer? or do you have it running nonstop to check whenever a slayer is created?
