Looking for second opinions. part of my rewiring scheme is to go ahead and utilize the "pause" terminals on the board to install a momentary push button. I'm also wanting to put an E-stop in but I recall Derek saying it wasn't a true E-stop. So I was going to install one of those big E-stop buttons between my main power effectively killing power to everything immediately though that would cause me to lose home, current coordinate system, etc. Can anyone clarify how the E-stop on the board functions when it's activated?

Dan,
I've noticed that Fusion 360 also has a tool to insert McMaster-Carr components. I've not used it, but that could be handy!

The E-Stop pin is just a hard reset... The same as hitting that button on the Uno board. It just boots the board up from scratch. In that sense, it's not a true E stop. The disadvantage to a total power-down is that the Z might drop into the work. The spring helps delay/prevent that to an extent, but it's still a consideration. What I would say is an e stop that cuts power to the router that at the same time takes the feed hold pin to ground. That way the motors just stop, locked in their position. I THINK (going purely from memory here) that you can then type ~ in the command line to resume the last feed command if you so chose. You could also restart it with a push switch on the Resume pin. Hopefully that sheds some light.

Hopefully that sheds some light. That does add some clarification thank you. I think I'll just do the pause button and my "kill it all" E-stop. The E-stop is just there in case all hell breaks loose. Fire, stuff flying everywhere, something critical breaking at which point the bit dropping into the work is the least of my worries. lol.

Here's another question, I'm ordering some more material for modifying my machine when I get back. I'm not there to look at it so can someone tell me what gauge the wires are? I'm thinking from recollection 22 but I'm not sure. Sorry for taking space with silliness but I don't wanna wait until I'm home to get materials.
FYI, Here's a fun tip for building CNC and kids... I was talking with my dad explaining the build process and what not and I remembered that I learned something I had not shared. While assembling my son had to M5 washers in his hand. NO big deal. Well, one came up missing. A search was negative. Couple minutes later my son started sneezing. Low and behold there was my missing washer. Shot from his right nostril. So there's your tip. Keep three-year-olds under watchful eyes lol.

Lol. I'm glad the kid dislodged it on his own.
Stepper wires are 22AWG.

Here's a good little tip when milling acrylics. I was milling some scrap acrylic for practice cuts for a project. Now, I don't know if it's cast or extruded but I believe it's the latter. Anyway, a couple times it would gum up so I'd have to pause, power of spindle, scrape off the crud and continue. What I started doing was using a toothpick, just touch the bit while running when I could see it building up. This worked excellent for keeping it clean. It was a 4 flute 3/64 mill so it wanted to gum up pretty quickly especially during boring operations.

Here's a tip for your spoil board. Attach it then, using whatever you wish (I used a 60 degree V-bit) just jog the machine manually to create a grid. As long as this spoil board stays attached the grid will always line up to my x and y axis making lining up material loads easier and faster. It also gives my a visual representation of the cutting limits.

Here's a little something to make your life easier if you decided to download the DXF files from the resources page. There are hundreds and they are really tough to browse through. Check out Jetcam if you're so inclined. Makes rooting through them much more efficient. Attachment Deleted
