Voron V0.2 R1 Z-Axis Linear Rail Stopper Fix - “Mushroom Mod"

“Mushroom Mod"

My buddy BallisticTech sent me the video linked below that explains an issue with overextrusion on the first few layers, followed by perfect prints. I have been battling this issue for WEEKS on my Fysetc V0.2 R1 kit. I have taken the z-axis apart, aligned, and recalibrated the machine countless times. Just when I almost gave up on having perfect prints on this thing, SmallBatchFactory found the issue! 

So, here is my fix for the Fysetc Linear Rail Endstops in 1, 2, and 3mm options. I have 2mm versions on mine and it has completely fixed this machine.

Issue:

I used this rail profile as the “spacer” between the end stop and the real MGN7 rail so the bearing have no chance of popping out.
