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

**njhussey** · 01-04-2015

Started on some wiring of the power circuit....

Those cable markers are a right bugger to get on, that's what's taking most time...

Looking good!

The CS Labs controller was such a pleasure to work with I have to say :) so well laid out. Definitely a good choice on that one.

The whole build is coming together nicely look forward to seeing it move soon!

I see you have the right tool at the ready.

My mate locked away all my hammers after my last keyboard smashing hissy Fit.! .

What size box are you using there. I am being dense today and can't find it in the thread earlier (I know it is most likely there but just being thick today) Nice set up by the way and may borrow some of your design set up with the rebuild I am in the process of (If you don't mind).

PS yes when the hammer looks like a solution that is bothering me; it is time to go for a walk or have a cuppa in the house and not touch anything that can break.

I might not have put the size here Michael so it's probably not you. It's 600 x 600 x 300, feel free to copy anything as most of my inspiration has come from seeing others builds, it's only what I think is a good layout for the control cabinet as I've tried to keep all power items to the left with noisy ones (power supply) to the bottom right as far away from the drives as possible as suggested by Dean.

Cheers Francis...I'm doing the connections between the drivers and the IP-M tomorrow and then I'll start on the safety side of things...cant wait for it to move either it's been about 5 years in the making!!

Today I was checking the wiring and powering up the relay to make sure that it bought the power on and that the door safety switch worked etc. and on measuring the voltage found that our single phase power supply is 242V which I think will mean that my PSU (25V+25V) will be putting out too high a voltage, or at least be too near the 80V limit of the AM882s for comfort....will dig out my calculations and have a look tomorrow :(

Neil chances are your mains power will most likely fluctuate up and down depending on time of day and demand around. My varies wildly upto 257v.!! . . . The drives will handle some over voltage without damage if just a slightly up but obviously not good running all the time above Max.!

It's down to 236V today, powered it up and geting a nice 71V at the drives. The drives drain it down to next to nothing in about 20 seconds (not timed but it's a short time) I'll still at a later date put a 240V relay in and put a resistor across it to drain it quicker in case someone goes in the panel within that time.

Now on to the various safety circuits....time for some head spinning!!
