My 2-axis setup uses a KFlop and SnapAmp system and will be run under KMotionCNC.
I will be using inductive proximity switches as limit switches and my plan is to use the 12V from the SnapAmp to power them. Is it best to route the signal through the KFlop or the SnapAmp? I was planning to use the 50pin cable into the SnapAmp, but thought I should check with you first.
Thank you,
David.

Hi David,
The best choice would be the 8 opto isolated inputs on SnapAmp. But there is not 12V coming out of SnapAmp. You will need to add an isolated 12V supply for that purpose.

Hi
Tom,
I am
supplying 12V from the power supply to KFlop, which I believe simply passes
through the board. Is that suitable to use and feed back to the
SnapAmp?
Thanks,
David.

Hi David,
A PC Power supply has +5V and +12V with a common ground. As you stated KFLOP passes the +12V through the board to several of the KFLOP Connectors (but not SnapAmp connectors). You could use that to power your sensors if you wish. Your Limit Switch wiring would then not be electrically isolated from KFLOP's ground or the PC's ground. If your system doesn't have a lot of noise this shouldn't be a problem.
