Is there something I should or shouldn't be doing when I use the machine in order to avoid this from happening in the future?? Understand the stress that caused the failure,? but not sure what I did to have caused this stress.?
As far as design is concerned, yes, I was happy that is was that simple to take apart,? but why does the shaft have to go through the center of that large piston in the first place, narrowing down at the point of entry? Why isn't the vertical, spiral drive shaft and gear simply on the same side as the motor??
I hope I will be able to reassemble to the same tight tolerances. After all, it is supposed to be repeatable to 0.1mm up/down.
