I’m wondering if someone could model this part
You might notice how off-center my Z-screws are. They’re not bent. It’s that the glue all shifted to one side before curing. The bambu A1 uses a linear guide rail to keep the Z-axis screw on target. The issue is that the weight of the gantry pulled my rail and my screw forward. Like so,
The glue is holding too strongly, there is no way I can get the AB glue off without running the risk of galling, gouging or bending the linear rod. Likewise, I can’t get the cap off without destroying it.
If I could print my own replacement cap, I can melt away the old cap and glue with acetone and then AB glue the new printed one into place properly. No risk of damaging the guide rail this way. I can put a few pieces of high density foam in there to center the rods properly until the epoxy cures.
I verified it is the way the rods set up by swapping the two rods around, it goes from making the gantry lean forwards, to making the gantry lean backwards.
