Limits switches or 'end stops' as they are known to the 3D printing community can be troublesome for Hobby CNC and 3D print setups. Many forums have discussion on how to stop the false triggers and most of it doesn't seem to work 100%.
This tutorial guides you through the process of adding X, Y, and Z-axis end stops/limit switches. This allows you to protect your machine from violent crashes, damage, and other unfortunate incidents.Wiring Limit Switches This tutorial guides you through the process of adding X, Y, and Z-axis end stops/limit switches. This allows you to protect your machine from violent crashes, damage, and other unfortunate incidents. I have all three of my home switches on a single digital input: they’re all wired NC so it runs an axis until a switch goes open. (That way, if the wiring breaks, it’ll register that it’s against a limit switch and stop, and I won’t run off an axis.)end switch cnc Wiring Limit Switches In its original design, the 3018 “Woodpecker” CNC Router, a cheap entry-level unit found on eBay and AliExpress, will happily tell the stepper motors to keep moving along the axis, even if the work bed or spindle carrier is bumping against the end of its range of movement.
Remove the linear rods from the carriage assembly for now. This is the easiest axis to add endstops. Print the x_positive and x_negative switch mounts. Solder wires to two of the limit switches on the common (C) and normally open (NO) terminals. Properly wiring a CNC shield V3 optical end stop is important to ensure its efficiency and accuracy. To do this, start by connecting the two terminals of the switch to the "NO" (normally open) pins of the end stop. Then, connect the positive terminal of the light sensor to the "COM" (common) pin. There are 4 main components for the Z-Axis: an upper and lower end limit clip, and a 2-part switch mount. All attach to the motor mount with snap-on, press-fit. The first part is this lower limit clip:end switch cnc There are two types of end switches wiring: Normally Opened end switches (NO) - switches are connected in parallel, if the head hits one of the switches the resistance becomes low (<10 Ohm). The wiring is simple but there is no indication if one of the switches is disconnected (broken wire).
