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

[njhussey]

No probs and cheers Lee....

I'm just reading up on safety strategys so I can see how many relay connections I need etc. Struggling to get my head round it, think I need to lock myself away from all distractions to get my head round it

OK another question, I presume the proxy switches to get are PNP NC ones (sods law as I have a good selection of used and new NPN NO ones that somehow didn't get left behind at my previous job!!)

If you haven't purchased your cable yet you might look at IGUS. They are a bit more but the difference in ease of flex and movement makes wiring up and setting up cable trays and runs so much easier. That is just my experience in helping a few folks rebuild older machines. I am seriously tempted to redo mine do to how much it makes getting a good clean cable run done. I don't own stock nor get a discount or anything just very happy with the product.

Hi Michael, I've already got the cable ta (which does seem quite flexible, but I've nothing to compare it with!) but if I have any problems with the cable runs I'll give IGUS a look cheers.

OK so once again work got in the way of progress.....however I managed to get an hour on it this afternoon just. I've made a "rough" X Axis stepper support plate and put it on the frame. Don't worry there will be plenty more bolts holding it on than are currently there!! One thing I've found is that my frame is not as square as I'd like, comes of rushing it to get it done before I lost the workshop at my old firm.

I've also added a couple of skate bearing idlers, these are temporary until I make proper shiney aluminium brackets as they're quite bendy! The plate will also eventually be either replaced or tidied up to make it look nicer as it looks really rough and ready and spoils the look of the build. However for the purpose of getting the mechanical build finished it'll do temporarily.

Been thinking about where to put the router and will be putting it an 80° angle mounted in a frame. As it's in a work environment I'll be building a frame that can be sheeted and have interlocked doors on it......something along the lines of the below:





This will have the added bonus of stopping the chips being flung everywhere, there will be a bin under the router to collect the swarf which will be slid out the front to empty it. I'll mount the router on the frame using epoxy putty pads where it's going to be bolted so the bolting doesn't induce any twisting in the router frame.

Have you thought about mounting it the other way so the X screws would be hanging down with the gantry horizontal.
It just seems to me quite high to reach and all the chip will fall on to the bottom screw. It is not going to need a big box to hold the chips. ..Clive

Yeah that's how I was originally going to have it but I thought with space now not being an issue I could have it round the other way which means that it's easier to load the work (top of bed is 1.75m, eye height, from floor, bottom is 1m from floor), not so much bending. I'll put a deflector on the bottom beam (and top) to deflect the chips away from the rail and ballscrew.

Ok so I got my spindle mount today....



20 mins later...



Just need to drill and tap the front plate this afternoon. Spindle should be delivered tomorrow or Thursday...

Had my cable markers delivered, should have enough here for a few control panels! Got 0 to 9 and E, N, L, X, Y & Z.

Neil you'll need much more deflection than that.!! . . . . I had my old machine vertical in both positions and the other way is much better for access and chip clearing.

The way you have it will need much more protection for the screws, both lower and upper. Just remember chips go up then back down again so they will settel on the top rail and screw.

I'd also urge you to cover the Z axis, to be honest I do this on all my machines now as it keeps a lot of crap out the works, but it's Esp important on vertical machine either way up as the dust settles either on the backside or onto rails etc.

Which way is best.? . . . .Well let me just say my new machine is going on wall when get chance and it will be other way to what you have.!!

Where did you get those markers.?

According the name on the real you should be able to get them http://www.edmundson-electrical.co.uk/
