Building platform/linear guide “jumps” 1mm to 2mm around 17mm point (height).
I wonder what the problem can be here. when the platform goes up out of the VAT, it goes up smoothly and steadily, yet around the 17mm point up until 19mm, every time the platform needs to come down, it “jumps” a mm down, kind of squashing a few micron layers of the freshly cured resin on the model.
At this point, a heavier model may come off the platform because of the violent shock or the model gets a “glitch” in its appearance, a clear line of about a mm that shows something went wrong there.
I will post sample pictures of failed prints soon.
Can we have some sort of build plan/technical plan of the print platform and its connection to the screw? Is this an issue that has already occurred during test phases?
If so, what is the possible solution, do I simply need to bolt it loose and put it together again for smooth operation? Do I need to replace the screw/cylinder itself or the platform attachment?
Any support is welcome! (If I need to reorder a part I would gladly do so if it would cure the issue at hand. Thanks for some advice)
