Estlcam recommends starting with a 100nf capacitor and adding a 1k pull-up (v11 help, v12 has no pull-up option/help) if random input triggering persists. While I have had no issues using just a 10nf capacitor for some years now, I’ve just switched to optocouplers on all inputs (motivated by the addition of an inductive Z limit switch)… Added a momentary start/pause switch (to drawing and machine),
