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

[paulus.v]

I'm just starting to do the things I should have done before using the machine (Sorry Dean!!) and one thing is a touch plate (limit switches are also going to be dome ASAP) as I want to use Ger's 2010 screenset. Now I'm a bit thick when it comes to electrickery so I wanted to check I was doing this right before even cutting a wire.....

My limited understanding is that I can connect the -VE 24V DC to the tool via a croc clip (or can I permanently connect it to the spindle or frame?), the touch plate is wired to the -VE input (15 in my case)of the CSMIO IPM input and then I put +24V DC to the +VE (1 in my case) input?

Is there a better (correct) way to do it? Sorry for my stupidity

If you have the tool grounded via spindle/frame, you may permanently connect the 0V of your 24V PSU to ground. Then you have only the touch plate wired as you already did (but not pin 1 and 15, eventually 1-14 or 2-15 ).

I find very useful the "Probe Active" green led on the 2010 screenset that I also use. I made a habit touching the tool with the plate every time I use it to make sure it is working as expected.

The easiest and rapid way to find the corner of your workpiece (nonmetal) is by using a "triple edge finder" (or a double edge finder that is easier to make yourself). To find the center of the touchplate hole that corresponds to the corner of the workpiece you have to use the excelent '2010 X-Y Probing Wizard'.

Oooops....you are correct, luckily I've got it wired 2 & 15...... Yes got the 0V wired to the frames earth so I just had the one wire to thread through the cable chains....

I don't fully trust it at the moment so like you I check the connection every now and again. I must admit that it's been a complete revelation this screenset and the touch plate, it's spurring me on to do the home and limit switches ASAP now...

I was thinking of making a corner touch plate, now I think I will....got some Ali plate somewhere to play with

Well last weekend I flew my plane that I made with my router....so this is a look what I've made on my machine post :)

Pity it wasn't a glider - must have been some good thermals under those clouds!

Well done - great sense of satisfaction in building something using a machine you built yourself. Nice landing, too!

Cheers Neale, the wing loading is such that it can thermal, it's a real floater. It was satisfying telling everyone who asked about the plane that I made it from scratch on my CNC router I also made myself!

The landing was a good one, second had one hop skip and a jump

Neil Beautiful job. You obviously can fly as well. Brill.

Brilliant job!
The sky was very cinematic too, you couldn't have picked a better backdrop for filming,
