I am installing the XYZ probe on a Millwright machine that we drive using Openbuilds Control. When I connect the probe and ground lines, it works properly with the probe and z-probe macros, so we are using it. If I connect the 5V line, it just lights up and indicates "touched" immediately when the magnet is put on the collet. For now I'm leaving this unconnected. I am going to try swapping the probe plate with one I have at home to see if there is a problem with it. Any thoughts?
Does it work fine without V+? If so, then thats what your 3rd party controller needs. As per docs:xyzprobe:wiringgeneric [OpenBuilds Documentation] V+ is optional. Otherwise, it sounds like a short between DC GND and AC Earth perhaps: XYZ Probe Plus with VFDs and other ground-loop inducing components
Thanks Peter.. Its comforting to see you are still here responding to our questions. We are using a dewalt 618 on this one rather than the 611, via the iorelay. Do you think that router is not similar in grounding? It is working, but I'm getting a little OCD hoping to get the leds functioning.
Router is double insulated, so not the issue then also if it works, not ground loop As for why adding the pull-up power triggers your controller - could ask your controller's manufacturer, or consider replacing that controller with a BlackBox X32? docs:blackbox-x32:start [OpenBuilds Documentation]
ha ha.. I was thinking the same thing on the black box. Its a makerspace, so we are eventually going to move up to a 4' x 4' unit. Im going to try swapping out the plate to be sure its not a short in there. then decide if it really matters and Im just too OCD right now
Interesting. I thought the signal input had a pullup, and closing the connection caused a level change to ground. Is it the opposite?
Correct, thats what the probe does. SIG to GND normally for probe contact, V+ adds 10K pullup on signal line, and positive side of LEDs through resistor, so when negative of LED (sig) touches GND via contact, LEDs light - pretty simple
