No.. you typed 50x50 cm.. sounds big my friend ;)
50x50mm sounds more like regular tube!

And by bench do you mean the base of the machine?

I've read several times that 80x80 with 3mm thickness is good for reducing flex and resonance. I think it was Boyan that typed that it was the perfect size and he seems to know what he's doing :)

What do you need them for? ;)

Are you thinking about steppers or maybe switches?
Plan ahead and order with one pin more than you need. I have similar connectors that doesn't have continuity in the shells so I need an extra pin to connect the wire shield. That's assuming that you will use shielded wire?

In theory you could have a big 20-25 connector for plugging everything in with one socket and then route it in connectorboxes on the machine itself.. :D

Hi Robert,thanks for the fast reply!
I am thinking to use them on the housing box to connect the cables that comes and goes from the electronic housing box.
Something like that:

Okey.. but do you want one for each motor and separate for switches or do you want only one big cable?

If bundling several signals in the same cable you loose the screen protection between them..

The normal that I see people using is one for limits and a one each for each motor

And of course if you want e-stop on the machine or probe or something like that.

Steppers are usually 4 signals + shield so 5 pins.

A switch depends on type of switch! But could be +, gnd, signal, shield so total 4 pins.
But it could also be + and gnd without shield for a simple mechanical switch with simpler wire for a total of 2 pins. But greater risk of interference.

So it all depends on your equipment :)

I just score that today for 80 euros, it is 540x600x20 mm,I am planning to cut it and make the z axis plate out of it.I will use my bandsaw and then my router to make the templates out of plywood and after that I will use the same tools to cut this Ali,as Joe Harris has already done very successfully I must say!!!.

Nice Nick!
You are brave to route that with a handheld router :D
Real action video is a must! ;)
