Thanks Craig, I didn't realise you were on the other side of the world :-)
I take your point about the overvolting the inputs!
Also I would not need the 12v supply that is feeding the Proximity sensors.
Roll overs are much easier to set up so I'll consider it.

So am I correct in assuming that X +++ and X--- can be wired in series and use the same input pin on the C10 ?? (Same for y & Z of course) but then again if all 5 switched are wired in series and are set normally closed, then any one of the switches being triggered will cause a stop ??
In this configuration do I need a home switch ?? or do I set this as the same as x+++ etc ??

Thanks,

George

So, I would use 2 limit switches for for each of the X & Y movement but only one for Z (Fully raised)
Can I double up on the Positive limit for the Home switch ? Or dont' I need the Home with this configuration ?
I have several of the limits switches so why not use them, any idea on the wiring ??

George

Hi,

Can I use the same switch for home and Limit for each of my axis or do I really need separate switches

Yes you can but I always recommend separate home and limit switches.

do I really need X+ and X- limit switches.

If you are going to have limit switches then yes....you need two switches per axis, one at the positive limit and another at the negative
limit. You could use 'soft limits' instead of limit switches. Genuine limit switches are safer but if you have good home switches
and homing procedures then soft limits are a reasonable proposition. If you  don't have good home switches and homing
procedures then you better have limits or you will crash badly and repeatedly.

Craig

Craig, I have several of these Proximity sensor, If you would like a couple I'll happily post them out to you.

10K resistor in place as shown and now working, thanks for the help.

With the sensor wired this way I get 'Cant Jog to x Limit. Input state LED is Lit.
If I cover the sensor then jogging is OK, The input state LED goes out!
Looks like I may have too much or too little Voltage at the input pin,.
The sensor is working backwards ??

I have just Migrated to MAch 4 with an ESS Smoothstepper+C11+C10s breakout boards.

I have a 3 axis Gantry router and want to place my limit and home switches,
Can I use the same switch for home and Limit for each of my axis or do I really need separate switches, do I really need X+ and X- limit switches.

I'm using the sensor shown but I 'm having trouble wiring it in. I'm applying 12v to sensors +ve & -ve with a 2K external resistor across the Black and Brown terminals.  Black terminal then is fed to the Input of the BOB.   Is this correct

 I've been an idiot. I had one of my jumpers incorrectly set. How I missed it I'll never know.
Thanks for your help it has been very much appreciated.
ESS + C11 now have movement.

Craig, you've been very patient, but for now I will carry on with the new configuration.

I have purchased a C10+ Laser from Endurance Lasers so now to get it working.

I hope you'll forgive the bother I have given you and maybe I can still raise questions..

Yep, done that. That's how my machine has been configured and operating for a number of years (Mach3 no ESS)

Drives are MSD542
Step and dir LED's light up correctly.
