【Application and Function】Suitable for GRBL control board and Mach3 systems etc. By connecting the CNC signal input port (tool setting port),it can achieve quickly finding the mind, looking for edges, looking for a round heart, measuring workbench and other functions.effectively avoid the secondary clamping of the workpiece during processing.( Tips: it's developed for DIY application, not recommended for industrial use) 【 Specification】 power: DC5-24V, repeatability accuracy: 0.01 mm/ 0.0004 in, feedrate: 50-200 mm/min, over travel protection distance: X- ±4mm/0.16 in, Y- ±4mm/ 0.16 in, Z- 2mm/ 0.08in, XY axis trigger force: 0.5-0.82N, Z axis trigger force: 2.7N. (Note: ensure the sensitivity of the tool setter is higher than this edge finder/trigger force less than 2.7N if working with a tool setter) 【3 wires】①Red-VCC (DC5-24V power);Yelow: IO/ Signal Output;Black- GND(DCM); ②NPN-NO Indicator light: green light when power on, red light after triggering; ③NPN-NC Indicator light: green light when power on, red light after triggering; ( Low-level IO signal output when powered and turns to High-level signal output when Triggered) 【Material 】 Shell is made of fine frosted black oxidized aluminum alloy with a flat surface anti-roll design;3D touch probe is machined from stainless steel up and down, the ball head is made of tungsten steel ball, which has the advantage of wear resistance(Note:the concentricity is fine-tuned to within 0.05 before delivery.Please measure and adjust it by yourself after receiving the goods.Be sure to use ER11 spring chuck of AAA or above,otherwise concentricity of probe tip will be affected) 【Package Include】1PC 3D touch probe+1PC Stainless steel probe tip+1PC cable+1PC Storage box for storing probe YIDOFENG CNC 3D Touch Probe Edge Finder,XYZ Coordinate Measuring Sensor with 2M Cable and 6 MM Shank Compatible with Mach3 and GRBL,for GRBL CNC Router
