The SmoothStepper is good at picking up any noise that is about so a lot of people need to use the filtering. On my Mill I occasionally had problems with the E-Stop triggering when I switched on the motor or the air brake was switched off, this was during the Beta testing when there was no filtering. Greg added it to the plugin and I found that I only needed 1.43 in the E-Stop box. The next thing was the MPG was implemented and this again gave me noise problems so again I entered 1.43 and that solved my problems.
The lathe I dont need any filtering at all.
It will just depend on each individual machine and how noisy the environment is, I have always taken good care with regards shielding and also I try to keep the 5v signal wires as short as possible, I have 24v working all my I/O on the lathe and convert to 5v just prior to it entering the BOB.
50µs will be fine, just means the SS will ignore any signals that are that or shorter in time but as its such a minimal time anyway its not going to cause you problems.
