Help me I think my endstops stopped
-
So, I have converted my Ender V2 to Duet and added a Hemera and a budget BLtouch. Everything worked fine except when I went to create my mesh(assuming I know the right way) I click Mesh Bed Compensation it goes off the front of the bed. so I catch the off switch prior to crash. And so I made some adjustment to my offset and tried again and this time when I hit homeall it crashed into the X axis endstop for about 2 seconds until I could stop it.
Now neither my X or Y endstops work; M119 shows not stopped for both positions. if I change it over to S0 the show no-endstop. so its not recognizing them.
Ive tried:
- reverting to last config.g/homex/y/z/all
*completely re config.json-ing like deleted all my settings and reconfigured and got back to no adjustments.
*reflashing the firmware
Nothing is working to get this thing back to those endstops being working and it really seems like something has stop electrically working in there. This is redick. im a EE and I literally have done nothing incredible tortuous enough to fry a switch contact.
So if anyone knowing the power routing or how that bus works that could hlep me out I would be eternally grateful to you. I am so sad that I spent a ton of money and havent even got a single print.
Could the endstops circuitry just have went bad from a single small and not long X endstop crash? I literally have not touched it and now both y and X are toast it seems.
Like could it be dust or metal shvings that are particle size that floated in or something? im freakin out. like this is the first issue that ive had with this board and I literall just got it and got it to the point of alllllmost being able to print.

@adalton5683 post your current config. Setting them to S0 turns them off...

yeah I know it turns them off but I tried it. and yeah it only turned the bit to 0 so I swapped it back. Main thing is I think the bus they run on is no longer working. but I dont know how it could have shorted.
Is there any kind of selector that I may have accidentally set in Gcode that turns them off? or removes the power from them?
updated the last post with my full config

@adalton5683 that looks fine, nothing I can see as being wrong.
So are you saying that testing with M119 that they don't change from not stopped to stopped when triggered?
You may want to install the endstops plugin to make it easier to test them https://github.com/Duet3D/DSF-Plugins/releases -
@jay_s_uk
yeah they show not stopped set to S0 and they show no-endstop when set to S1 -
@adalton5683 Installed the plugin
when I hit the X or Y endstop the plugin shows no change. Both columns say no for all axes.

@adalton5683![ ]

@adalton5683 @adalton5683 and it stays like that when either are activated.
-
@adalton5683 I would go through and check your wiring. If you have a multimeter, check that the endstop resistance changes when triggered. There's very little you can do to break the endstop inputs of the board
-
Does the board you are using have LEDs on the endstop inputs like the Duet2?
If so, make sure they switch from lit to unlit when you click the endswitches.
-
@alankilian said in Help me I think my endstops stopped:
If so, make sure they switch from lit to unlit when you click the endswitches.
they won't always go lit to unlit if normally open (will go unlit to lit when pressed)
-
Yeah, I just meant sometimes they are lit and sometimes they are unlit.
Sorry, I should have said "toggle" instead of "click"
It's hard to get it right.Also, @adalton5683 HERE is a page where someone did something similar.
It's a long page, and the endstops are at the end. -
@alankilian
Yeah I had already looked at this page when I had trouble setting up my bl touch but I found that issue.The reason I think it is hardware is I have base from the confit tool setup on normal end stops from my ender. So the setup and settings should not mess with it. I
So unless there is somehow a jumper or something that can auto change its spot or something code wise that I could have put in that changes and output bus then I think I have fried my output 5 and 6.
One thing I am thinking is maybe a piece of the stranded wires got in somewhere from making the valve terms. But I can’t find any.I’m an electrical engineer but I’m not super electronics heavy in specialty so I get uncomfortable when it’s needed to probe into a board with metal. I’ve got the grounding and anti static equipment thought and I think that’s what it’s going to come to.
Does anyone know anything about what I should be seeing on those two inputs and how they should behave electrically? When I get off work today I’m going to meter all the pins and see what they do on actuation.
-
Is it possible to swap my end stops to other connectors and then reassign? I did just a basic setup so I have some free pins, just don’t know which will work.
-
First thing is to test your switches.
Can you post images of the wires on the switch and the wires in the connector on the Duet board?
It looks like the Duet Mini 5+ does not have endstop LEDs, so that's no help to you.
If we know what kind of endstop switch you are using and how they are wired into your board that will help.
-
-
OK, are those are regular normally-closed or normally-open switches or are they optical-interruptor type switches?
Do you have a Volt/Ohm meter you can use to test them?
-
@alankilian theyre the basic 1923 switch. The switch is able to be wired to NO or NC so what I have it on rn is the outside rails which is C and NC so im setup normally closed. Do you know what voltage im supposed to be seeing cross the two leads of the switch if its operating right with setting S1?
-
also since its a mechanical switch idk how possible it is to fry it that easy. id say the board is probably more easily broke than a mechanical switch. theres literally just traces and the lil box spring switch.
for giggle and shts im gonna go ahead and order a few new switches. but have them be inductive switches.
