Rambo Patch adding capacitor to z-min & zero sense

I came across this today and was wondering what adding 100pf capacitors to the z-min and zero sense circuit does?


This guide was for a very old model of the RAMBo board (From the Taz 1-2) that required these be added to allow it to work with our Z-axis setup. As long as you aren’t working on a board from 5+ years ago this won’t apply and isn’t anything to be worried about. :slight_smile:


Sorry to butt in but i’m wondering if this ‘Rambo patch’ would apply to a RAMBo V1.3 board?
