Here's the limit switch circuit I'm using. One end of the limit switches goes to 12V (24V is also ok). The other ends go through current limiting resistors (a 1.0 kOhm resistor might work a little better) to the anodes. The cathodes are connected to ground. grbl already initializes the D9, D10 and D...

Another option is Sorbothane. You can get 4 half-spheres 3/4 inch in diameter on ebay for less than $10. They should fit nicely on the bottom of the 20mm extrusions.

Not to mention that socket head screws are much easier to hand tighten. I'm upgrading from a v1 to a v2 mechanical kit and keeping the socket head screws for the parts I am more likely to need to take apart and put back together but going with the button heads for stuff like attaching wheels and idl...

Not sure if this will help, but I used this article as the basis for my SSR remote switch: Tom Benedict Builds a Relay Box for His Taig CNC Mill.

Roy, what multiplier should we use for Vref when setting current limits? Or asked another way, what is the value of the current sense resistor? Is it the same as for the SureStepr (Current Limit = Vref x 2.5)?
