Includes 2 GT2 belt clamps (notched half of DGC3)

Limit switches send an all important signal to "stop moving now!". Best practice for limit switches is to permit overtravel detection without collision. The FirePick switches are crude in comparison with industry standards that have evolved to the ideal of optical detectors. However, the FirePick switches also serve as cheap mechanical stops and prevent greater damage to the rest of the machine. M5 screw can be tightened with pushbutton in bracket.

NOTE: A carriage moving at full tilt can really smash into a limit switch, so hand tighten the M5 screw just enough to hold the switch in place for gentle, calibration impact but loose enough to slide on harsh impact. A severe, sharp impact can crack an acrylic stage. Tighten gently and you will get more bang for your buck.

@Sources:

• version 4: UNTESTED http://shpws.me/pKVV 6 stops and 6 clamps (1/12)
• version 3: TESTED http://shpws.me/nRgl GT2 clamp now has M3 nut recess for ease of assembly
• version 2: TESTED http://shpws.me/nxWE also includes DGC3 GT2 belt clamp (top only) (2 brackets/2 clamps)
• version 1: FAIL http://shpws.me/n8vK 2 limit switch brackets. Functional but cannot be adjusted with pushbutton in place.

@Requires:

• Pushbutton
• M5 10mm screw
• M5 extrusion nut

In the following, order does matter:

1. Attach bracket to extrusion using M5 screw and nut.
2. Gently tighten M5 screw per note, above
3. Solder wires to pushbutton
4. Attach button to bracket

TIP: If you want to save time and money, omit the pushbutton on the maximum range limit switch bracket. The bracket will act as a simple mechanical stop.
