Biesse Rover 346 Retrofit

Sleep ???? What is this "sleep" you talk about???
It is 6:24 AM here and i have yet to catch some zzzzzzzzzz .............in an hour or two.
It is nice to see the progress you are making.

OK, so The machines limit switches go directly to the servo drives I imagine to shutoff the motion.
I want them to go to Linuxcnc also, so Is there an issue with energizing a relay for each limit switch and sending one contact into Linuxcnc and the other into the drive or should I leave it the way it is? I would obviously leave the switches N/C so the relay is on all the time in case of wire breakage it will trip.

Is this done this way normally or leave it directly attached to the servo drives?

I don't see any reason to bother with a relay, if it is a voltage-level signal can simply connect to both LinuxCNC and the drive.

It is different power supplies from different sources and I dont know if there is a voltage differential between the two. I would rather keep them seperate.

I could just bring in the nput to the 7i77 as Limit switch, and fire an output to go to the drive.

Using 7i77 general-purpose outputs to the drive is likely to have the same problem with not-common GND, and has no advantage over just having the existing software-controlled amp-enable controlling the drive with the limit switch input to the drive hard-wired (or left open, depending on logic). The amp-enable outputs (ENA- / ENA+) on the 7i77 act as switches, so common-GND is not required.

That would make my day if I could find schematics......

I sent you a email through this forum. I have a schematic and manual for you, just need your address and they will send it to you.
