Công Tắc Giới Hạn Kết Nối V1.2 Cho Reprap Ramps 1.4

Giới thiệu Công Tắc Giới Hạn Kết Nối V1.2 Cho Reprap Ramps 1.4

Item Type: Switch
Application: 3D Printing
Customized with high quality wire, it can be resistant to 2A and 300V voltage. Insulation is very wide temperature range(it can reach 80 degrees), which is much better than the ordinary thin copper wires.
Not easy to pull off, while plug is convenient.
Mechanical limit switch Schematic
Analytical principle
1 end: power supply (VCC)
2 end: ground (GND)
3 end: connect with 2
4 end: Signal
When touching no obstacles, signal terminal connects VCC, take the value of the high level, namely 1.
When touching obstacle, the signal terminal connect GND by mechanical switch, take the value of low, namely 0.
Based on the above logic, you can set to the low level when trigger, the microcontroller receives a low level (1), to control the motor stops.
If you use Marlin firmware, Configuration.h not need to ify the appropriate configuration files, keep the default:
const bool X_ENDSTOPS_INVERTING = true ;.
const bool Y_ENDSTOPS_INVERTING = true;
const bool Z_ENDSTOPS_INVERTING = true;
Tip: Genarally, the system need at least three mechanical switches.
colour: Picture color
Material: PC
Mechanical switch Size: 42mm * 18mm
Package Contents:
1 * 3D Printer Endstop Switch
Only the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
