Hi all,
I am making a CNC like project and I am at the stage of connecting the end stop switches. I have an Arduino with a motor shield (controls 2 step motors) and an Intel Edison that has a heap of sensors connected to it. My question is where do the end stop switches connect to?
FYI I am following this guide: http://www.instructables.com/id/Indoor-CNC-Garden/ but cannot seem to find where they connect to in the guide.
Thanks in advance,
Probably in the PDF they want you to upgrade so you can download it.

No......
This is the Destructibles wiring diagram.
Another case of I know how I did it, this is what it does, these are the parts, but I'm not going to give you the vital info on connecting it all.
Note the "wiring diagram" does show lots of wires connected to the shield, but not what is on the other end.
Tom...... :o :o :o :o
Where would the end stops usually connect to on an Arduino controlled CNC?
I am using this code here to code the CNC: GcodeCNCDemo/GcodeCNCDemo2Axis at master · MarginallyClever/GcodeCNCDemo · GitHub
That's a V1 motorshield, with ancient L293 chips.
Totally unsuitable for anything else than two tiny 6volt brushed toy motors.
Forget about the stepper motors pictured.

also look up the AccelStepper library
A GRBL shield or a RAMPS shield is what is required for working with stepper motors - provided the stepper motors do not draw more than about 1.5 amps each. For motors that use more current you will need larger drivers that can't be accommodated on a shield.
