Dewalt 5-Amp E-Stop

Post by Undecaffeinated » Wed Sep 27, 2017 7:47 pm

My Shapeoko3 XL is arriving on Monday and I'm planning to add an E-Stop.

I ordered this:
https://www.amazon.com/uxcell-Mushroom- ... B00548585A

I had seen someone using it here:
http://community.carbide3d.com/t/how-to ... op/3020/21

However after ordering I noticed the product page contradicts itself and says it's actually only 5 amps rather than the 10 in the title.
I assume it is because it is 5A for the NC and 5A for the NO sides for a total of 10A.
Is anyone currently using this with the Dewalt (supposedly draws 7A max) and are you using a relay?

I burnt one of these style of Estops up on my 3D printer (not the exact one you linked to ....but similar). It only took a few weeks to die. So When I added one to my Shapeoko2 I ran it to a Solid state relay. I put the Relay and a outlet in a metal gang box (grounded , and I'm using the box as the relay heat sink). That was a few years ago, and it's still running fine.
The Extra cost of the relay is worth it in not having to replace the estop every few weeks.

Thanks for the info, I think I'll definitely add relay into the mix.
Thinking about it, I could also use the relay to turn the spindle on/off via the shapeoko (assuming it has an output for it).

If you want to use a relay to control the spindle, check out https://www.shapeoko.com/wiki/index.php ... Y_Solution
