Comments sought on new build: A CNC Router for RC Gliders and Planes

That's the only thing I'm clear on Dean, what I'm struggling to get my head round is which terminals look at which relays. I'm not going to be switching AC now I don't think as I've got a 230V contactor with 24v DC coil coming (3 NO & 1 NC contact) so will switch the AC through there...

Easy neil.

13 & 14 NO Contact
23 & 24 NO
33 & 34 NO
41 & 42 NC

If you want Short circuit across contacts detection then use Dual channel E-stop which means 2 x terminals on each E-stop connected as below.
Contact #1 between S21 & S22
Contact #2 between S31 & S32
Then jump wire between S11 & S12

Reset button Between S13 & S14

Ok so those are the connect through terminals, which are the ones that control them? There's 11 & 12, 21 & 22, 31 & 32.....

Just been laying out and fixing down a few more things, not had much time on this in the last couple of days...



Waiting on my Pilz X3 to arrive before I fix the last few bits down....

Makes you feel like a Kid waiting for Xmas again doesn't it Neil.. . . So close but just not coming quick enough. .

Looking good so far you'll be there soon.

Cheers!!

They laughed at me this morning because I got excited when another delivery from Chalon came which meant I could do the last bit of trunking on the panel!!

Quick hand drawing of power circuit so far. Pilz X3 is switching the contactor to kill power on e-stop.

Christmas morning today...Pilz came so knuckling down to finish the wiring diagrams so I can get it wired up....

Power and Limit switch wiring diagrams...
