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

[njhussey]

Just one thing done in lunch today, the second cable tray/bracket/energy chain on the X axis...

[njhussey]

Ok so managed a bit more this afternoon....cut the Y axis back plate, only 2 M6 bolts in at the moment...don't worry Clive ill be putting lots more in soon!!!





Put one bit of energy chain on the Z axis to get the cable tray bracket mounting height....



Slowly slowly catchy monkey....

Just wondering why you need two X chains!!

Just wondering why you need two X chains!!

One for power and one for signals and water of course....

Looking good Neil. I also went for 2 chains with power down one side and signals down the other. Even with this setup I had a few false e-stops but I'm pretty sure it was because of the long limit switch cables to the Z axis straight into the breakout board. Hopefully with my new 24V limits through the relay it should sort that one -when I get round to wiring them up!

This is the way I have done it because I wanted the chain out of the way. All of the signals and motor power, water etc run through it without any problems. Although I am thinking of removing the water tube and fitting a small rad. with a fan on it on to the Z axis.
.
Dean has done this and it works very well ( Just a small sealed system about 1 pint of water).

Clive, my router is going vertical so that's not really an option for me, looks a great solution though! I'm going to build a frame/enclosure to put it in which will eventually be fully enclosed with interlocked doors (safety because it's at work) which will also stop the chips from being flung all around the shop floor!



I like the idea of keeping the water cooling on the Z axis, might look at small PC radiators and fans....

That's the badger Clive!!....

I'm torn between mounting it on the Z axis or on the enclosure frame. I'm sure that the small volume will be OK but I'm erring on the side of caution and thinking of mounting it on the frame, that way there is a bit more water in the system. I've got a 240V small 200 l/hr pond pump, but it's a submersible one so I might just go with that in a bucket with a lid for the time being and then adapt the water circuit later....decisions decisions!

Hi Neil,

Good progress recently....

If you want to go down the PC rad and pump route let me know, as I may have a spare 120mm rad (possibly 2), fans and possibly a pump/res unit I can let you have, as I've recently upgraded to 240/280/360/420mm in most of my watercooled PCs.
