K40 DSP upgrade layout
Posted: Sat Aug 06, 2016 1:34 pm
So, completely new to laser-cutting, but I've got all my bits from Marco, and I'm starting to upgrade the K40 I bought a few weeks back. This is all in the nature of trying things out at a relatively cheap price before going whole-hog and DIY'ing (well, semi-DIY'ing, Marco'll be getting more business 
I'm an embedded s/w engineer, so not afraid to get my hands dirty
Anyway, I've removed all the things in the side-compartment, and my plan is to put a piece of wood on the base, screw that down in the existing holes, and then I can position things easily by just screwing into the wood rather than having to go through metal. The basic plan looks something like:
But I have a question - this pushes the high-tension supply wire that goes to the laser tube up against the metal side of the case. Now it's the standard red insulated cable, so I'm assuming it's designed for this, and is ok, but "trust, but verify" makes me ask: could it arc ? Is there anything else I ought to be aware of before doing this ?
The layout will ultimately looks something like one of the below:
I've see tell of a K40 upgrade-to-the-DSP guide, but it's not obvious from looking around the site, and Marco didn't email me the URL along with the instructions / software etc, so does anyone know where that is ?
Cheers. I get the feeling there'll be more questions later, sorry guys [grin].

... so things will just about fit...
It did occur to me that there's space for a 'double-decker' approach, which would actually mean I could put the K40 PSU close to where it originally was, but it's more effort to do that, and it'd be harder to change anything out, not to mention harder to wire, so unless there's a good reason not to, the single-level approach seems better.
