New board install on old LRv3

Hi all,

Well i got my board, pri ted the extended case (credit to whom ever it was that did it, thanks!) And havebit mostly installed.

I powered it up and i think i have a all the endstops in the right locations, except i saw that the instructions say they should be “normally closed” and when triggered they breack the connection and light goes off.

I can see the logic behind this, but for what ever reason PAST CHRIS (damm that dude is questionable) has wired all the endstops as “NORMALLY OPEN”.

I fished around in the web interface hopping for a “invert endstop section” but no joy, or at least i can find.

Please tell me there is a way i can invert endstops!

If you change all these in the Yaml from high, to low

“limit_neg_pin: gpio.25:high”

To

“limit_neg_pin: gpio.25:low”

it should work. Pretty sure you can even do it in the settings in the GUI but mine is running right now and I can;t check it for you.

Ok,

Yaml, i know what it means and its a text file, but where do i edit it?

I wont be anywhere near the machine for another 5 hours or so, so if you gmcould have a look for it in the gui that would much preferred to diving into text files, lol

Yeah do that first. Mine is still running and as soon as it is done I am leaving for dinner.

Ok,
i found the config files
config yaml

and i found the “limit_neg_pin: gpio.25:low” you mention to change it too.
But some of the instances were actually set on the positive pin. I changed them all to “limit_neg_pin: gpio.25:low” saved in and then uploaded it back to the jackpot.

I tried to use the reboot command but nothing changed, so I power cycled the board and it still did not change the endstop activation.

Do i need to write this to firmware or something (I tried to reload the files, but that didnt seem to do anything)

Right,

Not sure what changed (and that shits me) but everything is running now

I had one of the y motors was reveresed, so i pysically reversed the plug and that fixed that.

All the endstops seem to be working too, not sure what changed.

The only thing that doesnt work is the probe and aftwr a bit of diagnostics i found the wie soldered on to the probe was brokenbut touching so moving t
It around still had connection cos it was still touching.
So new touch probe is conning next!
