Birdhouse endstop (Hall endstop)

thingiverse

I have settled with mechanical endstops for a long time, but I recently started questioning their accuracy and didn't like how carriers were crushing against them. To address this issue, I decided to use hall sensors, which are more precise and don't require any physical contact between the carriage and the endstop switch. I purchased my Hall sensors from Aliexpress for approximately 3€. Note that you will need magnets to trigger Hall sensors; I had some 12mm disc magnets on hand. My Delta printer is now pretty silent due to the hall endstops, which home much more quietly than mechanical switches. The accuracy also seems spot on. Printer Settings: Kossel Mini Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2 Infill: 100% Notes: I noticed that the hall sensors had nice red LED lights, which is why I made the housing pretty thin so they could glow through the plastic. This makes your printer 5% cooler. Post-Printing: Putting everything together Print out 3x Hall sensor housings and magnet holders (if you decide to use 12mm disc magnets). Modify your hall sensor's sensor so it would be at a 90-degree angle from the electronics board. Place the hall sensor in its housing and use regular M4 screws to mount it to the printer. I managed to use the same bolts that kept the mechanical endstops in place. Note: Hall sensors use three-wire setup (5V, GND, signal). If you have used passive endstops (only two wires - GND, signal) then you will need to provide an additional 5V wire also. Put magnets into the magnet holder and secure the holder to the carriages using superglue.
