Endstops not stopping external drivers on the expansion header
-
I have started with a blank sd card and re did all the files from scratch and still the end stops don't work with the external drives. I tried firmware 1.19.2 and now have 1.20RC4 neither worked. If I plug a standard stepper into the integrated driver it stops when the endstop is triggered. but it will not stop any of the drives on the breakout. does the breakout not support STOP? I am using the ethernet but I have a WIFI laying around and also a DUEX5 but not sure how to run 5 external drivers from them. It is just frustrating because everything moves just as it should it just wont stop… I cleaned up the config file when I wrote the new one with some of the suggestions I found in the other forum posts. It just seems like the end stop is not communicating to the breakout board. Is there a way to test this? I have included the new config file. I have not set final size, thermocouples, fans, and all that stuff yet but that should not matter. All the movement; and end stop info is correct. I did see a rather rude guy posting on here about the same issue but he uploaded new firmware and that solved his problem or so he said ( not quite sure if he was truly all there, if you know what I mean).

I am puzzled by your report. The endstops work independently of whether you are using internal or external drivers, so there should be no difference between the two.
The first step in debugging endstop issues is to test the endstops and their configuration. Go to the Settings -> Machine Properties page or Duet Web Control. In the "Endstop hit" column, the first, second and third rows show the state of the X, Y and Z endstops. Ignore the fact that column to the left says "Drive", because the "Endstop hit" column is unrelated to drives. Check that the X, Y and Z endstop states displayed there follow the state of the switches themselves.

They all register fine, 0,1,2 all say no and when triped they say yes. X,Y,Z all still move even when it says yes in that column.

sure why not? It is only when you home that they will serve…
-
So you are saying the only time an endstop works is when you are executing a home command?

Yes
-
Ok i will write all the home files and give it a shot, thank you.
-
yes the firmware will take hard limits coded into the config.g to take care of the print limits once homed
-
No dice I ended up with two broken sendstops LOL. As i said earlier if I plug a standard stepper into the the integrated stepper drivers it functions just fine. It is just the expansion that is is not communicating with. Everything move is the correct direction to home just does not trigger the external drives to stop. I am going to swap the Ethernet board with a Wifi I have laying around and see what happens. maybe there is a short in the 50 pin connector. I am going to use the same sd card so everything is equal. Will see what happens.
-
Problem solved!!!!!! not sure what is wrong with the ethernet board but wifi works beautifully.Guess I will just hang on to the ethernet board for my sons delta that will use the integrated drivers. Thanks guys for all the help….
-
So is it just a faulty board or other people have similar problems with endstops when using expansion breakout board?
-
I am guessing just a faulty expansion header. The rest of the board operates just fine but the 50 pin plug has something going on with it. Usually the problem is the endstop or the wiring so I was going nuts trying to figure out what was going on. This has been my first real issue that was not of my doing and I have built 4 printers all with duet electronics.
-
Is there anywhere I can send this Ethernet board to have it repaired?
-
Bear in mind that when you map axis drivers using M584, that does not map endstops. You must still use the XYZ endstop inputs on the Duet.
-
It was, I know it is a board issue. I swapped to my wifi board that I was saving for a different printer and it works fine. The only thing I changed was the board, I even swapped the sdcard so it was running identical settings and firmware. I don't want a free repair I will gladly pay to have it done, but just don't know of anyone qualified to send it to.
-
I don't see how it can be a hardware problem. Please can you try the latest release (1.20.1RC2) and if that has the same problem, share your config.g and homing files.
-
Sure give me a day or two to switch the boards around. in advance these are my config.g and home files.

also the firmware is 1.20.1RC2

I don't know if this might be relevant but when I changed my CoreXY to XYUV, after mapping the drives I had to move the axes maxima to a position in the gcode file that was after the M584 command. I see in the config.g that your M208 is before the M584.
Also this from the Wiki might be relevant.
"Assigning a drive using M584 does not remove its old assignment. Therefore, if you assign a drive that defaults to being an extruder drive, you should also assign the extruder drives explicitly as in the above example. Failure to do so may result in unexpected behaviour".
Edit. That's big printer BTW!
-
Ok so I switched back to the Ethernet and used the same SD card and verified that the firmware is the undated one and when homing the endstops do not trigger the motors to stop. I even swapped the min and max codes so the max comes first and still the same. Not sure what the deal is.
