Hi Andy,
My cabinet is about 790 x 790 x 275 deep. As I said in previous posts, please take this circuit diagram as a guide as to how I have wired my machine - it is from research on here and other places and is not an expert guide and may not be best practice, correct or even safe!? It may also have mistakes in it. I found it useful looking at other peoples diagrams and that is why i'm uploading it, but please do your own and be sure in your own mind that everything is correct before you wire things up. I don't want to be blamed for that infamous magic smoke!!
Cheers
Joe

Thanks Joe, that's extremely helpful.
Don't worry, I'll be sure to place a sticker on the inside of my cabinet that ensures any faults or issues are referred back to you! Any magic smoke captured will be posted directly to you - refunds are expected :)
On a serious note though - you're very correct to point that out :) I'll be cross referencing every connection to the manual, and redrawing from scratch for a different breakout board and axis layout.

Hi Joe,
Currently puzzling over the implementation of the PNOZ X1.
My understanding of your diagram is, if the coil in the PNOZ has +24V (i.e. E-Stop not pushed), we get:
- The coil contactor closed for the drive PSU
- A +24V E Stop signal to the IP-M
- A lit up E-Stop reset switch light (?!)
- The 24V pilot light is off
With the E-Stop pressed, all the above reverse.
Am I reading that correctly? I would have expected the two lights to be the other way around.
Thanks,
Andy

I’m talking about hand routing the side plates for my machine out of tooling plate which is why I was concerned over using 1/4” bits - seems a bit fragile for my heavy hands. In his video Joe says he used a 10mm bit in a 1/2” collect which sounded less likely to snap.

Oh ok. Fair point. Put it this way. I'd rather use a cheap 6mm bit and have it snap when something happens, than trying to hold on to a router with a 10mm bit when it catches on something and doesn't snap. My vote is for the 6mm bit all day.

As for flute count, yes single flute would be best, but you can also go two or even three flutes. Three flutes have a thicker core so they'll be the sturdiest, but they will gum up the easiest. If you can strap an air line to the router and point it at the bit, then that will help immensely. Also with three flute you'll need to move quickly to keep your chip load the same. Too slow and you'll be rubbing, not cutting. Which leads to heat, which leads to gumming up.
Try stepping down in increments of 0.5mm at a time to start with.Last edited by Nealieboyee; 31-08-2019 at 09:55 AM.

0.5mm was my plan - gonna take a while as the plates are 25mm thick!!!

Make sure your end mill has flutes long enough. I'm using 6mm bits and the flute length is only 15mm.
