Since you were running all day without problems could it be you bar length is too long? I note the barfeeder can cut a set amount of material in the settings and if it is exceeded I have noticed it wants a adjustment. I would review what it was doing when it was working verses now. Something has changed and you may be surprised by what you find by just stepping back sometimes and saying MMM. Machines can behave like children sometimes. Oh it did what I told it do do right. Good luck to you and there are some experts on this barfeeder who post regularly on this site. Haas has a good product demonstrated in the barfeeder 300. I do not use ours often but would like to and recieving orders that would need it is the only holdup. Good luck.
