Isolating probe body from 5v

One tricky thing took me a while to figure out. The Langmuir touch probe exposes it’s 5V input to the shaft, which will short out to ground through the spindle encoder ground. Langmuir seems to handle this by fully isolating the 24V power supply from the rest of the DC using a B0524S-2WR2 (isolated 24V from 5V). I solved it by disassembling the probe and making a small delrin insert that fits between the spring (which is 5V) and the top/shaft of the probe, isolating the probe. [image]
