The Z axis is the feeder and the A axis is the saw head.

The down and up feed of the saw head is controlled by an electric cylinder controlled by Mach3.

When the feeder go back to Zero(home) the feeder pneumatic cylinder is open and , feeder hit Z home switch, reset Z DRO to zero and then the feeder pneumatic cylinder close to continue feeding material.

That's when the feeder cylinder close that sometime the Z limit switch is triggered and got into Estop.

Jeff

did you take a look at the video when the material feeder goto zero and the cylinder close?

Thanks again, Jeff

Thanks, I wanted to try with the relay but wanted to know if there was other ways to do it,

Thanks again for your time, Jeff

BTW, I have one home switch for homing the saw and another for the saw over travel if it want to go too low when cutting so if they are deactivated, this would not be a problem.

Thanks a lot for the reply.

It's a limit switch on a feeder that's use for a CNC cold saw.

When I send the feeder back to +0.125, I have a G28.1 Z0.000 and then a G92 Z0.0.

After that, the pneumatic cylinder close to start feeding the material again.

Sometime, when the cylinder close, this activate the Z home switch (Feeder home) and I get an emergency stop.

I would like to deactivate the Z home switch just before the cylinder close and the feeder move from the Z limit switch, after the feeder has moved from thre switch, I would reactivate the Z limit switch.

Here's a video of my modified manual to CNC cold saw, hope this is enough info.

I'm using an ESS with PMDX-126 BOB.

Would like to use port 3.

Do I need another BOB in order to do this?
