Z probe type?

norwestie

I have an Anycubic Kossel LP w/Mini 5+ with the stock Z probe. RRF guide lists 10 different types of probes. Which is the Kossel's?

@norwestie I chose type 5 but I get Z probe already triggered. It is wired to io3.out on out+gnd (tried in+gnd also). This is how it is set up in config.g: M558 P5 C"^temp2" H5 F120 T6000

That's a good question. What is the stock Kossel probe? what does it look like? What wires does it have? Photo?

@phaedrux

It is a 2 wire connection and feels like a microswitch

Phaedrux

Yes that looks like a microswitch.

Try P8 instead of P5.

If it's showing triggered all the time, invert the signal by adding ! to the front of the pin name in M558.

M558 P8 C"^!zprobe.in" H5 F120 T6000

Are you really wanting to use temp2 pin? Why not the zprobe.in pin?

"Are you really wanting to use temp2 pin? Why not the zprobe.in pin?"
I scoured the wiring diagram many times but don't see probe.in. I found it on the Maestro but where is it on the Mini 5+?
I added the ! and changed the probe type but a G30 command does not move the carriage and the message is Z probe not triggered

@norwestie said in Z probe type?:

w/Mini 5+

Sorry, my bad. For some reason I thought you had a Duet2, but you mentioned you had a mini5 + which means you have more generalized io pins.

But still, why temp2 instead of an io port? Choosing an io port as shown in the bottom left of the board in this image would make more sense. Same as you'd use for an endstop.

@phaedrux That is my problem (at least one of them). It is plugged into io3.out but the config says temp2. I must have selected something wrong in the RRF tool.
I changed the M558 line and saved then issued a G30 but the carriage doesn't drop. I can manually command it down with DWC. Where should I look for that fix?

Phaedrux

If you're using io_3 your M558 line should look something like this..

M558 P8 C"^io3.in" H5 F120 T6000

Also ensure that you are connecting your switch to the io3.in and gnd pins on the connector. It doesn't matter which goes to which.

I am using a similar probe. You can't tell if it is a SPST or SPDT snap action swtich unless you tested to see if the switch is NC or NO. That will make a difference too. NC is prefered. Hook up a test light or DMM and check. The config is different if it active low or hgh.

What is your M574 config line look like?
