Grbl and the Grblshield support limit switches. Many of the people on this forum (including me) are using Grblshields with limit switches.

i'm discovering that! Ever since i hit submit on that post... although I'm guessing I will need to solder onto the grblShield somewhere to get access to those Arduino pins?

Also, I've seen folks talking about pogo pins... and folks using hall-effect sensors... and folks using optical interrupters... and folks using mechanical switches... what's the community consensus when it comes to accuracy? Certainly Caleb's hall effects sensors are pretty awesome... i mean, the light up! Any pros/cons to different methods? Also, any advice on the cleanest way to hook up to the latest grblShield is appreciated.

I plan on using a screw shield, I found one that fits between the grblShield and arduino uno.

Here is the link to the one I have

I am in the process of making my control box now, and I am debating using grblShield with a Arduino UNO or grblShield with a breakout board and Mach3 / LinuxCNC, or somehow wire up both and figure out a way to switch between them, I had got the Screw-Shield to make it easier to wire.

I think Rule #9 applies to this video. In fact, I'm starting to worry myself about all of the large and small upgrades I want to make to my machine. Oh well, I suppose I will just except my fate.

nice video... i just bought one of those from inventables... but I think i'm a little bummed that the crank doesn't spin allowing you to rotate without it needing to slip in your hand.

But, on second thought, with your thoughts about vibrations and things (and noise now that I think about it), I might not want the crank on there at all.

Yeah, it's a bummer that the crank doesn't spin, but it's still very nice.

As far as vibration goes, I really can't tell a difference, and that's when I'm running it at my max jog speed. So, I would say even if it does introduce a little bit of vibration when it spins as fast as it does in my video, It's probably not going to be much of a problem at the much slower feed rate speeds when running a job.

Hi Caleb,
I would like to follow your approach in electronics. As time permits, could you please draw a rough schematic for connections from C10 board to each driver and related components?
Just a feedback on your videos, they are great and please keep them coming!
Thank you
J.

Sure thing, I should be able to put something together by tomorrow.

Alright, so here's a rough diagram of my wiring setup. Below is a fairly high resolution image of the diagram, and also a link to the Visio file of the diagram itself.

Credit for the images of the C10 breakout board and DRV 8825 boards should go to CNC4PC.com and pololu.com
