Is there any reason to not cover the top of the limit switches ? They look a little unfinished to me but maybe there is good reason for it? I’ve printed some covers which look far nicer than bare PCB. Maybe arcdroid will answer this?
Do you have pictures installed, hard to say without seeing what you have done
If you are using the “ArcDroid Sensor Covers” from Makerworld, they work great. I’ve been using them on my ‘droid for several months now.
