Ok thanks- I'll keep an eye out for that when I order!

[GrahamWhite]

So I've learned another lesson on ordering from the USA- again the metric /imperial beast raises it's head again in the form of spur gears on the reduction drives!
And with a local company wanting nearly £100 each to machine up the appropriate MOD 1.0 spur replacement, I'm having to go for an off the shelf spur, have it bored out and get a collar turned up to fit it instead!

So decided it was time to start laying out the control box

I'm gathering you try to keep the mains power stuff away from signal stuff as best as possible.
Want to try and keep VFD in there as well as I seem to have enough space ....unless I'm missing some bits! nothing big I hope!
Been looking at control cable and wondered how expensive you need to go?
4 core 0.75mm screened Flexible cable £4.13 per meter https://www.rapidonline.com/lappkabe...0-75mm-63-4774
or cheaper 809 cy flex at £2.98 per meter https://www.rapidonline.com/lappkabe...0-75mm-63-4331
Do I run the home/limit switches(magnetic PNP) in 3 core- screened also?

At 1.20 euros a meter was that for chain flex? I've seen prices for cy shielded from £0.60p per m but it doesn't suggest constant bending i.e for chain drive
I found this company at £1.94 per m for chain flex https://www.tme.eu/gb/details/cf881....shielded/igus/
or is the chain flex over the top?? and standard CY shielded fine?

I bought this. 1 size fits all 1mm2

I believe it says class 5 flex 20x OD bending property.

Non moving bending property 6x OD

So I finally got my Z axis done

Will probably swap out the MDF that the spindle is mounted on for some Ali plate at some point.

Added end supports to the x axis mount points for added stability.
