Euclid Probe / Railcore frustration. Any advice?

@arnold_r_clark
Thank you very much! The conditional code is what I'm struggling with. I'm concerned about it crashing if it doesn't get stowed before it gets turned off, or if a print fails, and I re-start it remotely, or whatever.
Your code is basically how I started off.... Just a series of movements.
Then everyone started telling me that I was going to destroy my machine, and I had to set it up to detect the presence of the probe.
I think at 48 years old, considering that I've never stepped in front of a moving train, or fallen off a building, or anything like that, It's probably safe to say that I'm capable of checking the head before I start a print..
It would just be nice to have the safety of the code.

@steve-lynch, this is how I check after the probe was supposed to drop.
M400 G4 P250 ; Wait 250ms if {sensors.probes[0].value[0]} < 750 echo "Error: Clickey not dropped. Value: " ^ {sensors.probes[0].value[0]} M112 ; Emergency stop. -

@steve-lynch the conditional gcode checks in the Euclid examples ARE safety checks. You don't need extra devices or sensors or anything. The change in probe state is reliable.
If you dont want conditional gcode checks then use the Euclid RRF2 macro examples. Those are tried and true. The developement of Euclid was done under RRF2.
Where have you been soliciting advice from? I do not see any questions or requests for help either at the Euclid discord channel, or in the Railcore discord. The Euclid discord is primary support venue.
As to the answers to some of your questions- which are hard because of the deleted posts along the way-
-
You can probe more than 3 points to calculate 3 point leveling.
-
If your LED's are on with the probe half disconnected then you have mis-wired the device.
-
condiotnal gcode documentation- I am not a coder either but the documentation here in the conditional gcode forum and the dozuki are where I learned what I needed to know and implement.
https://duet3d.dozuki.com/Wiki/GCode_Meta_Commands -
As to whether or not the checks are required- I think that they are worth having. As all things mechanical, nothing is foolproof, only small probablilities. You'd be surprised how quick an errant screw or nozzle clearing needle will find its way to the magnets and complete the circuit.
If you need more specific help, come join us at the Discord channel linked in the docs.

I'm not a discord user, I mean, I occasionally log in if I have to, but I can't stand the platform. I have been seeking help in the railcore group, and a couple other 3d printing groups. I didn't know there was an official support discord.
My probe is behaving as it should. Probe value is zero if it's connected, and 1000 if button is depressed, or probe is removed.
I actually want to use the conditional code, I just don't understand it. I have the example .g files you provide, but I don't know what to uncomment, or any of that.
I build CNC tool changers, I'm quite aware that errant debris can cause huge problems in devices. I realize a probe will probably just break, or fall off, but I'm used to a 3 LB razor blade going 25,000 rpm.... one of those gets away from you, and it's a real shit show. So I'm a big fan of safety checks.
I'll follow your link for the meta commands.
If I can't sort it out, I'll bite the bullet, and hop on discord I guess.

@steve-lynch I watch the Euclid channel and some of the other printer channels there. It the least of the evils...
To confirm, what is the issue you are trying to wrangle?
I assume that you are using fixed dock setup.
To confirm, you are using the examples from either the euclidprobe.com or git.io/euclid repo. They should be the same.
As far as the echo statements, and which need to or are are commented out, you should not have to touch them. There are really debug statements to aid users in tracking what is going on. you can comment them all out if you want.
I put them in and left them because of all the effort to figure out the proper syntax. I felt it was easier to keep in and comment it out in case someone down the road needed them.
For example in the deployprobe.g, the "Probe Value =" is the token that is displayed on the DWC interface.
; *********************************************************** ; Euclid Probe Fixed Dock M401 Deploy Probe Macro ; RRF3.X Firmware Example ; saveas system/deployprobe.g ; comments and echo statements throughout are provided for convenience ; *********************************************************** ; echo "Running deployprobe.g" ; if !move.axes[0].homed || !move.axes[1].homed ; If the printer hasn't been homed, home it ; M98 P"0:/sys/homexy.g" ; uncomment next line to echo the probe deploy state echo "Object Model Deployuser token =" ^sensors.probes[0].deployedByUser M564 H1 S0 ; Allow movement BEYOND axes boundaries (for Y to reach probe dock) G91 ; relative positioning echo "Lift Z in advance of deploy" G1 H2 Z15 F3000 ; move Z 15 for clearance above dock. ; ; need to figure out some safety check on this G90 ; absolute positioning ; uncomment next line to echo the probe value ; echo "Probe Value =" ^sensors.probes[0].value[0] if sensors.probes[0].value[0]!=1000 ; if sensor is value other than 1000 do this ; uncomment next line to echo the probe deploy state ; echo "deployuser token = " ^sensors.probes[0].deployedByUser ; echo "Probe State = " ^sensors.probes[0].value[0] abort "deployprobe start value Probe already picked up.

@arnold_r_clark said in Euclid Probe / Railcore frustration. Any advice?:
conditional g code is NOT required for that to process to occur.
This practice is called 'defensive programming'. That's having a gracefully handling also for conditions that 'can never occur'.

@steve-lynch Here are all my files for my RailCore, running a Duet3 Mini and 1LC toolboard.
sinned helped me as I was having an issue also.
download.zip.txt
Hope they help you. -
Hey Man,
I just noticed I had never responded to thank you for sending me these files. I wanted to apologize.
I know you probably don't Remember, but either way, it bothered me that I had not acknowledged you...So again Thanks so much!
Being able to see how you had it set up really helped me to understand how the different instruction sets interacted.
Take care!

@steve-lynch I have removed you from my Rude User and Hit lists.
Its cool, glad it helped you.
Laters,
Paul
