This is my first post here. I assembled the MPCNC during the winter and just started working on it again but I’m having an issue I cannot figure out.
During a cut while the MPCNC is raising and lowering the z-axis, the T8 brass nut is not staying in place. When the z-axis lowers, the T8 brass nut raises and pushes the screws up which prevents the MPCNC from cutting at the right depth. I’m not sure why it’s doing this and would appreciate in help in figuring it out.
Should I epoxy the T8 brass nut down to the plastic piece so it cannot move up and down?
Here are a couple videos showing the problem (Caution videos are LOUD):
