It was in Xnaron's first post. Did I see it? Sure I did. Did I listen. No I did not. There isn't that much heat radiating off the hot end to melt the effector plate, I thought to myself. I ended up popping two of my balls off my effector plate (the second within a half hour of replacing the first) and chalked it up to not curing the screw/ball assemblies in an oven as suggested.. Maybe my basement was too cold. Whatever.xnaron wrote:The stock seemecnc hot end will work in this but don't use the standoffs. You want to keep the hotend away from the printed effector.
So I was printing the part blower http://repables.com/r/212/" onclick="window.open(this.href);return false; (because my last/first one was made out of PLA and was sagging pretty bad. New one is ABS) and as it's printing I'm thinking 'Huh... I don't remember it looking quite like that...'
That's when the ball broke and I stopped the print (for the second time). So then the printer sat dead. I got a new ball/screw the next day and removed the effector to install the new one when I saw it. The heat from the hot end might not be enough to MELT the effector... but it IS enough to make it nice and soft.
It was really hard to take pictures of, but the effector is bent and warped all to hell. No wonder the balls broke. They were getting pretty hot themselves, and with the added pressure of a bent effector, they ended up letting go. I now have my hot end mounted well below the effector and it's nice and cool. I'm just sure glad I had made a second effector for another hot end before all this happened or I would have had to put the stock arms back in to print a new one. It would not have been fun. And now that it's working properly, the first thing I'm making is another effector (currently printing).
