Wiring Limit switches to Leadshine MX3660

[Clive S]

I believe you can wire all your limit switches in series (if you're using mechanical) and just use one input for limits. Then use one home switch for each axis.

Yes but you can do it with sensors as well but mechanical are mush easier to deal with I thought it showed you how to connect them in the manual.

It does,



I just though I'd specify mechanical to stop people chiming in that you couldn't do it with sensors....you can it just adds a few ms on to the time it takes to sense the limit.

I didn't see anything in the manual about wiring up in series. I'll have another look tho because I often do miss things!

Thanks for the image Neil, however what does NPN and PNP mean?

Am I right in thinking then, that input 1 can be X home, input 2 is Y home, and input 3 is Z home. Then use input 4 for all the other limit switches in series?

Thanks everyone

If you are using Mach3 you can wire every homing switch in series, as Mach3 moves the axis until the switch is tripped and then back it to the untripped status. It Homes each axis separately in the order Z, Y, X (Z first to get the tool high and out of the way). Other CNC software may do similar, but I have only used Mach3.

Have a look at this article http://www.learningaboutelectronics....PNP-transistor . I presume that you are asking about limit switches, which can be regarded as transistor switches, although I am being a bit simplistic about it.

Cheers,

I am using LinuxCNC but I've only just started out with it so I am unsure yet as to how it homes itself etc... It's all new to me tbh.

Ok start with the basics are you using mechanical switches? Tell us in as much details where you are at and if you are using a mill or a router ..Clive

I'm using mechanical switches, it's a small router that I'm using them on. Only a small working envelope (approx 250mm x 250mm x 75mm).
