New start

[Desertboy]

I know that if I start running with this it will never get changed :D
Limits will go through relays but I've read that homes should get connected without relays or logic circuits to get the best repeatability? :)

I feel so close now!!

I think if you use Solid state relays it's not an issue as they switch a lot quicker.

But just buy new switches is the proper solution and obviously what you're thinking, you can still play without home switches.

Aren't these the same switches but NC?

I guess you are right!
Im so sick of soldering and shrinktubes and that crap.. hoped I was done :D
Swedish post has introduced a new fee for packages that come from outside of eu.. so ordering from China will get expensive from now on.
Except for VAT there will be an extra charge for every package. Think the smallest charge was around 7£.. This takes away the freedom of just shopping cheap stuff.

Anyway :D
Will have a play tomorrow and try to make sense of pulses/mm.
Had it at 160 at the moment but didn't seem quite right.

Relays would work - but if you are worried about broken wires, loose connections, etc, then you need a separate relay at every location where there is a switch. Not a practical way forwards, even more wiring needed, and will cost more than replacing the switches! The only real answer is NC switches, wired in series. This is particularly important for limit switches as you really do want these to function reliably, but I'm not sure if you are using combined home/limit switches. If these are just for homing and you have separate limit switches (NC, I hope), then the home switches are not safety-critical and you probably won't actually break anything if something in the home switch circuits fails.

Thanks!
Not using combined home/limits!
Went with mechanical switches for limits and they are no/nc.. so it might be ok :)

.... and there is no reason to make it more complicated than it has to be.

So true :)

I have been curious for some time now.. where in Sweden are you from?
And do you make money from your cnc endeavours or is it only hobby usage?
Have found alot of inspiration from your YouTube channel!
