z probe on kossel linear plus anycubic

bahnstormer

Good Evening everyone, or rather early morning as I write this.

I just put a Duet wifi onto a stock Anycubic Kossel Linear Plus.

This machine uses a switch for the z probe....

I was following Danal's excellent guide, up until he left the firmware at 2.xxx

Then I moved on to 3.xxx

My sticking point is the configurator for Z probe.

I just don't know what to select

I tried to do normal Z, inverted Z, e0stop, inverted e0stop.

Nothing works though.

There was some talk of rewiring the Z switch but I would prefer to have it work with just config changes at this time.

Can anyone suggest the proper settings for this Anycubic Kossel Linear Plus?

I have the Z probe into the e0 port on the board.

Change the zprobe.in to e0stop if that's the pin you're using.

Or am I missing something?

FIRMWARE_VERSION: 3.1.1

Also a good idea to update to 3.2.2

Thank you very much for replying!

Which combination of drop down choices from the configurator would give me that result?

Or is this a custom code I'd have to enter?

To update the topic -
@Phaedrux suggestion worked. I now show Z probe 0 and when pressed, z probe 1000

However, during auto calibration, the head crashes into the bed
If I press the z stop with my finger early, i see it goes to 1000 in teh webcontrol, but it still tries to crash into the bed, and I have to kill the power. Any thoughts there?

As to why the whole problem started:

It seems like the Configurator, the wiki and the firmware are not quite in sync with each other.

So you can use the configurator, get sort of close by guessing as it doesn't tell you what all the drops downs mean, then you have to manually edit the config file yourself.

Set the input pin to e0stop and the modulation pin to none. Most types of Z probe don't use a modulation pin.

bahnstormer

@dc42 unfortunately not possible from the drop down

here's a screen shot of my options:

only under the modulation pin drop down is the e0stop available. Is this a bug in the configurator?

Phaedrux

Yes that doesn't seem to be intentional. There is a major overhaul to the config tool coming soon. Thanks for bringing that to our attention.

The config tool as it is now is limited to begin with, so the intention has always been that it gets you a starting point for syntax and command layout and then you would go through the customization process for your actually printer and doing the testing and commissioning to get it all working correctly.

bahnstormer

@phaedrux awesome look forward to the new version.

If you can I would write

" the intention has always been that it gets you a starting point for syntax and command layout and then you would go through the customization process"

at the start of the configurator for other new users like me who assume that it is 100% all you need
