Problem with z probe - led light works as expected, but the probe doesn't always change state
I've installed the probe which arrived with the ratrig v minion full kit.
Sometimes it shows as "open", and sometimes as "triggered" but not necessarily in correlation with the proximity to the pei sheet.
I re-crimped the connectors twice but no help there.
Important to mention - the led light on the probe does change color as expected.

I would double check your wiring again. What you are describing sounds like a poor connection somewhere
I agree, but I suspect the poor wiring is on the probe side
Is there a way to check the signal wire?
I would use a multimeter
yes, but what do I need to look for?
And the signal wire is connected alone to a port
So what do I measure it against with?
Sometimes it shows as "open", and sometimes as "triggered" but not necessarily in correlation with the proximity to the pei sheet.The reason for this is usually that the "floating" value (should be high or low) sits around ~3v, that is usually solved with a pullup or pulldown, depending on what the probe does when it's circuit is closed. So yeah try looking at the voltage between gnd and the signal pin Also look closely at the probe and check which type it is
It's the cheap one
Blue head
You have configured a NPN-NC (like super pinda), but if it's the one that shipped with the minion it is not an NPN-NC probe
That's PNP-NO if i remember correctly
Let me check
It should say what it is and what voltage range it expects on the tiny label wrapped around the end
second, I am checking
Need to screw it off
Says npn nc
Something 5v
And something 2mm
I think I’m screwed
It does indeed, this should work with your config
So yeah, you're prolly right to suspect the probe
I haven't seen this type before, i don't know if they changed their supplier
Oh man
I sent an email to Ratrig today about this. I hope they’ll send me a new probe
I have a spare beacon actually but couldn’t find a mount for it for the v minion tool head
I’ll just have to wait and see 😔
they will you have a two year european warranty 😄
Yeah it’s just the waiting that annoys
needs EVA 3 (which needs a different X endstop, but i believe there are mods ready to go on printables)
I’ll try to sort out the smart filament sensor 2 in the meanwhile
Yes totally get it, doesn't help that they're in full v-core 4 production ramp up mode
They are doing good stuff
It's been a hell of a ride getting this thing ready. I've had 2 full time jobs the last 6 months.
But it's totally worth it, i'm proud of the work we've done!
You should be 🙏🏻
Thanks for trying with me!
I’ll get it sorted out
