Z Gantry Hangup
Posted: Thu Aug 01, 2013 2:34 pm
I have an issue with my Z-axis that when it goes to home bringing the gantry down quickly, it'll often hangup somewhere. My first thought was the threaded rod catching somewhere. I've also been thinking about getting new v-wheels as I believe I may have flattened them when I was first assembling. Maybe it's getting stuck in those grooves. A simple tap on the top will get it to settle back down, but if I don't catch it quick enough it sends the parts it floats on down to the stepper and seizes them making nasty noises.
Usually it happens just before the min endstop. I have seen it happen once or twice closer to the top, but I haven't printed many tall things at this point.
Is this a common problem with a known solution or do you have some other suggestions what I should check?
