N/O Probe issue was created by natholego11
Im not sure what happened as of late. but I recently have been getting an error with my probe when probing. I keep getting the error "probe is already tripped when starting G38.2 or G38.3 move" blah blah blah.

with the probe plugged in the HALmeter is showing that its "TRUE" and when I actuate the probe it goes to "FALSE"


and here is a link to the probe I have.



here is my HAL code.

Net probe-in ....... _not
Remove _not at the end of the pin name.

ive tried with both _not and without the not, and I still get the same message.

You may have more than one issue.

First the polarity needs to be correct
( set it so the Halshow dot goes yellow when the probe is activated)

In addition, it's possible you have a noise issue. This may be fixable
by de-bouncing the pin, either in hal of by installing firmware with input
filtering (7i96_inmd.bit) and using the inm pin instead of the GPIO pin.

and here is a link to the probe I have.
 

I don't have a solution, but I have the same probe that I will soon be integrating into LinuxCNC, however mine is NC, not NO. I also have the toolsetter accessory that goes with an identical second probe, which comes with a slightly weaker spring, so you can set the spindle probe length with the toolsetter. There's even a magnet on the bottom.

If it helps, here is an electrical breakdown of the board on the probe. The reverse is just contacts to the pogo pins. The important part - and the point of this reply - is the pinout of the type-c port, so you can make your own cable . I will use shielded microphone cable. The solution could be that simple.

A5-CC1 & B5-CC2, are tied on the probe PCB. The little plug PCB's larger pads are +24v & gnd, and while there are passives on the little plug PCB, I don't know one way or the other if they affect the signal. It seems easy enough to remove them and bridge their pads if it comes to that.

I just measured the capacitance and resistance between the conductors, comparing the original cable the probe came with and the solderable PCB. They are identical.
