Really dumb question ahead...

In the past I have run my machine with soft limits and have not had a problem.
I have a home switch for the X and Y only,

How does on go about having a homing set of switches and limit switches.? apparently if I put the same pin info for both a home and limit switch the machine e-stops and will not move after and will not let me reset it.
or do you do a home switch on one end, and the limit of the other end?

Then something is not configured correctly. If you look at the Diagnostics screen, are the Limit LED's on?

You can put the switches anywhere you want. At one end only, or one at each end. It doesn't matter.

Lets talk about the X axis. On the Zero side (home) I have a switch that is configured as "Home". on the far side I currently have nothing and I am using soft-limits to control how far the spindle (on the X) moves. I am thinking of adding another sensor to that end and configure it as a Limit +.

Now I can set my home switch to also be a limit switch by just replicating the pin and port info into the Limit field. okay fine. until I hit the switch.
The machine goes into E-stop mode and whenever I hit the reset button, since the physical switch in pushed in, it tell me:

"The reset logic of the software is active!, remove the reset condition with pressing the blinking reset button on the screen. If the reset condition cannot be removed can be due to an external e-stop button is pressed in or a limit switch on the machine is active. Please check the diagnostics page for the input signals condition"

So what I end up having to do in the case to get the machine moving again, is to clear the pin information on the pressed limit/home switch and reset the software e-stop.
not sure if this is how its supposed to work.

Click the "Override Limits" button next to the Reset button, and you'll be able to jog off of the switch.

Thank you ger21. that worked well. In your opinion, what is best, physical or soft limits?

[OlfCNC]

Both.

[FoxCNC1]

exactly my thoughts, and I was thinking physical switches a little farther than the soft maybe?

Yes, because if you're using softlimits, you don't want to be hitting the switches except as a last resort.

my opinion this is none , in a mass production scenario (I use a cycling G-Code) it gives me problems specially if it`s already contaminated with saw dust, oil residues etc. once it does it can halt the nesting process then I need to go back again to zero to restart the process.

But it could give you more problems if you accidentally crashing the machine into the hardware limit with full speed damaging the machine, the ballscrews etc.
Then you can't do mass production even for days until you repair the machine.
Rehoming and repositioning is a much smaller problem IMO.

on a jig scenario, I program CAMs on that particular area of the table, it doesnt go anywhere within that area, it will just keep on cycling on that area all over again then park on it`s programmed parking space after 1 cycle, reload materials and start all over again, with a limit switch installed specially if it`s faulty already it can make the whole nesting process go offset and hit my metal jigs, it gives me more problems with the switches installed
