Homeing does not work - fadeing x Endstop



  • Hi Community,

    I just bought myself a Duet 2 Ethernet to upgrade my Ender 3 Pro however I was not able to get it working so far.
    I followed the installation guides and documentation and got the firmware from: https://configtool.reprapfirmware.org - choosed the ender 3 pro presets and let most settings on the recommended settings - the only special is that I want to use a BL-Touch, see the screenshot in the appendix. After logging in the web interface and homing my machine every axis only moves some milimeters and then stops and the x endstop LED starts to fade.
    The X and Y axis move away from the endstop side (i guess thats normal but i dont remember how it was before)
    When I want to home x it always moves first a little bit the Z axis and after that the x starts to move.

    So I started to test some stuff, this is what I noticed:

    No matter what I home, it is always the X endstop that fades, even if I home Y and have no x endstop wired it still fades.
    If i push again on homeing it repeates the same process - axis move a littel then stops, but i am always able to repeate over and over again until the end of the machine is reached.
    The BL Touch sensor is always in the print mode / drawn in and shineing red.
    When I home for example the x axis, it only moves as said a little bit and then it fades, how ever if i then push the x endstop the light goes from fade to bright light until i let the endstop again it returns to fade. After it fades once i can only get it off again by restarting the mainboard.
    I dont get any error masseges from the web interface.

    Thank you for your time and effort for helping me!IMG_1694.jpg

  • Hi,

    Well you posted a picture of the stepper motor connections and I can see from them the connections may not properly crimped.

    Each little metal connector has a section to crimp on the bare ware and another section to crimp on the insulation.

    It doesn't look like you have any crimp on the insulation.

    Perhaps you have crimp issues on your endstop connections.

  • Hi fcwilt,

    thanks for your fast answer.
    I know that you usualy crimp with one of the -lets call them metal noses/ feet- on the bare copper cable and one on the isolation rubber. To my knowladge that is only for protection, that the cable dont have a chance to contact and create a short circuit, and it also ensures that the crimped connectort on the copper cable will not fall off easily when you pull on the cable, because the force will also spread to the rubber. -> maybe I am wrong about this, feel free to correct me 🙂

    I did not crimp the cables correct because they have a higher diameter (2x0.75²) and wont fit in the connectors. But I can ensure that I tested and there are 100% no short circuits between any cable.



  • You understanding of crimping is correct. The crimp on the insulation usually has a tighter hold than the crimp on the wire and provides protection against pulling the wire out of the contact.

    You remark about the endstop and fading has me confused as you did not show a picture of your endstop connections.

    When you say "fading" you mean the LED gets dimmer? If so that is caused by a loss of power either do to a poor connection or perhaps the power source is having some issue.

    Could you clarify a bit what is going on and when?

    Thanks.

  • what I do: power on printer -> log in via web-page -> home any axis f.ex. Y axis. (does not matter - all behave the same)

    what the printer does: z axis moves some mm down, y axis moves some mm front direction. (both maybe 3-5mm)
    then the machine stops and the X -endstop LED is glimming like seen in my first picture.
    ! In the picture i also pressed my Y - Stop just for comparison! when not pushed x and also y LEDs are not lid. when i push one by hand it glows normal. when i release it again the LED turns off again.
    I dont get any more informations like error messeges. In the Web Page the Homeing buttons turn blue like it did homed successful even though it didnt. However if I want to move any axis to a direction nothing happens.

    The switshes (x&y) are the normal Ender 3 Pro ones. Connection on board the two outher pins (Sign. and GND) and on Switch side also Sign and GND, both sides 3v3 not connected. No Z Switch connected because i want to use my bltouch.



  • Hi,

    OK execute from the web interface a M564 H0 S1 command.

    This will allow you to move on X,Y or Z via the jog buttons on the interface even though homing is not done.

    DWC Jog Buttons.jpg

    Verify that all axis move in the correct direction and from min to max without any problems.

    Frederick



  • Thanks for this tipp. Every Axis moved from min to max. (z was in wrong direction but i fixed that in the settings\config.g\M569 P2 S0 (before it was S1).

    While testing the X Endstop LED did not start to glimm.

    -> what can I do next 🙂



  • Now that you know the movements are in the right directions and you can cover the entire range from min to max try homing each axis separately.

    Frederick



  • Same behavior as before. When I click on the jog buttons (f.ex. Home X) the Z axis moves positiv direction for lets say 5mm, then the X axis moves 5mm positiv after that the z moves negative 5mm again and then the machine stops without any feedback however the X Endstop LED starts glimming.

    I now tried to use the M564 H0 S1 command again and tested after homeing to move any axis. The "homed" once didnt worked - the other ones did. [just for information - but i assume that is how it should behave - I am not experienced with reprap firmware since I just started so I test much with the hope that it can give you any information witch might help you to find out my problem 🙂 ]

    Behavior is simular to the Y axis.
    When trying to home Z it only moves up 5mm and then stops.

    It is only the X Endstop LED that starts glimming. Disconnecting the X Endstop Switch from the mainboard had no effect in this behavior (was just a frustration test ^^)

    M918 P1 E4 F2000000

    Direct connect display (eg 12864) is not supported on Duet 2 Wifi, only Maestro. Well, it sort-of is, but you need an adapter board and a special version of the firmware. If you've connected a screen, disconnect it.

    FIRMWARE_VERSION: 2.03

    That is an old version of the firmware, ideally update to the latest v2 firmware, which is 2.05.1. But your config.g should work with it.

    Generally, I can't see much wrong with your config.g. Please check your X endstop is wired correctly, as I think it's most likely that's what's causing the problem. See https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Connecting_different_types_of_endstop_switch

    You could try swapping the X and Y endstop connection, and see if the behaviour swaps to the Y axis.

    Finally, at the moment your homing files are not set up to use the BLTouch for homing Z; they're using a Z endstop. Replace these lines in homeall.g and homez.g:

    G1 H1 Z-265 F240        ; move Z down stopping at the endstop
    G90                     ; absolute positioning
    G92 Z0                  ; set Z position to axis minimum (you may want to adjust this)
    

    with

    G90                     ; absolute positioning
    G1 X15 Y15 F6000        ; go to first bed probe point and home Z
    G30                     ; home Z by probing the bed

    Is that correct 🙂 ?

    And the endstop is wired like this: on the duet mainboard only the two outer pins, (GND, 3v3, X Stop). on the ender 3 side i have the following pinout: (Signal, Ground, 3v3). So I wired GND -> GND, X Stop -> Signal and both 3v3 are not used.

    Thx for the help.
    Joe



  • So I now changed the X Endstop with the Z Endswitch because I dont use it anymore. It still doesnt work.
    After changing the lines shown in the last 2 posts I tryed to only home Z.
    The Z axis only moved some milimeters positive direction and then stopped and the webpage gave me this error.

    5afd6735-e434-4913-b58d-32c1bf894cb6-grafik.png

    If I press home all the x axis moves some mm, the y as well (both x and y home buttons then switch to homed) and then the Z axis starts moveing down and never stops, the BL Touch also dont work correct, it was always closed / triggered - like it behaves while printing.
    So i had to emergency stop just before the print had reached the bed - cause it would not have stopped.
    This error came after restart
    98c9f5c4-cc7f-438a-a5c5-d18cf65a26c3-grafik.png .

    FYI: When I power on the printer the BL Touch does this start process where it tests that it can trigger correct and that works every time.

    -> can someone tell me what the F is wrong with my setup? Before I switched from the Creality Mainboard v. 1.1.5 everything worked fine so I would guess all this behaviour must be from mistakes in wireing or firmware.
    however I feel like the wiring is as it is shown in the wiki.

    Where do you have the BLtouch wired up to? H4 is certainly incorrect. It should either be heater pin 3 or 7. Without that being correct you can't deploy or retract the pin.

    You are correct, it is H3/ Pin 8. I connected the BL Touch the recommended way from the wiki:

    Thx for this hint - this was an user error ^^.

    I will fix this after work and also review the rest of my code configurations before I waste your time 🙂



  • so here is an Update:
    after getting the BL Touch right and fixing the following files:

    retractprobe.g

    M280 P3 S90 I1
    

    Here is what happens:
    When I home X and Y axis, the printhead moves z positive, some mm (less then 5) into x/y positive direction (my endstops are low end/ so other direction and will never get triggered) and then z negative and stops there.-> he thinks the home was a success!
    The Z homeing works now (or at least it tests it once, the second / faster test doesnt work).

    After homeing all axis (doesnt matter if allhome/ or to home 1 by 1) the printer thinks that the point he is at the moment is his home (even if it is in the middle of the build plate because he never drives to the endstops). So i can move the X and Y axis only in more positive direction but not nevative (as long as I dont move positive first. then I am able to drive as much negative as I did positive before.)

    Edit:
    One other thing about the endstops. at the moment I used normaly open switches because i was not able to use normaly closed once - changeing the 1 to 0 and 0 to 1 in the config.g made no diffrence

    Endstops
    M574 X1 Y1 Z1 S1 
    

    same behavior as

    Endstops
    M574 X0 Y1 Z1 S1 
    

    How can this be?
    Any tipps what I can do next 🙂



  • Hi,

    So when you home X or Y the result is some small movement on X or Y in the positive direction.

    Correct?

    If so that is because your end stops are already triggered when the home begins.

    • The 1st move in the negative direction never happens because the end stop is triggered
    • The 2nd move in the positive direction happens as expected giving the 5 mm of movement in the positive direction
    • The 3rd move in the negative direction never happens because the end stop is triggered

    Try changing the M574 command to specify active low if it is now active high (or vice versa).

  • Hi,

    well thx for this hint. I directly homed again while holding the x endstop and it works as it should until I let it again.
    So now my question is why is it that my machine thinks he is always triggered even when the Endstop LEDs are not shineing. -> why doesnt it work when i change the M574 command from X0 to X1 or other direction or die S1 to S0?

    Greetings
    Joe

    Edit:

    I use NO Switches with 2 wires. So I wired only the 2 outer pins as said in this wiki: https://duet3d.dozuki.com/Guide/2.)+Wiring+your+Duet+2+WiFi-Ethernet/9?lang=en
    And I have the config.g as posted above. what would be the correct commands for my ender 3 with this setup? can anybody tell me I will test it then 🙂



  • Hi,

    In the M574 the number after the X,Y,Z specifies if the end stop is at the low or high end of the axis range.

    S1 specifies an active high input, S0 specifies active low.

    You need to use S0 since your switches, when closed, connect the input to ground.

    Frederick



  • Ok, then I have understood that correctly. So here is my endstop config from config.g

    Endstops
    M574 X1 Y1 Z1 S0
    

    and this is how i wired the x and y endstops on the duet:
    IMG_1700.jpg

    this is how both endstops (normaly closed) are connected:
    IMG_1701.jpg

    but they behave weird. When I interrupt the connection (pushing the trigger or just disconnect the switch) the red LED goes off and i am able to home correct. -> so the FW works as NO Switches.
    Here I have the x-endstop just connected and the board thinks it is triggered when it is not, but the disconnected y is not "triggered".

    IMG_1702.jpg

    In my understanding it shouldnt behave like this - might there be an overwrite file where I also have to change something because inverting the config.g to S0 or S1 makes both no diffrence in behaviour.

    But when I change thw wires on the switch side to NO it works fine. How ever I want to use them in NC mode.

    BTW can i scale the images down in this view ? that i dont spam pages ?

    Where are your endstops actually located? Left/right front/back?

    Low end of travel is to the left, high end to the right.
    Low end to the front, high end to the back.
    -x to the left, +x to the right.
    -y to the front, +y to the back.

    Your homeall file is setup for the switches to be at the low ends of travel. Is that still the case?

    What does your M574 line look like now?

    For the Ender 3 pro in RRF2 it should be M574 X1 Y1 Z1 S1



  • Hi,

    I havent changed anything on the positioning of the ender 3 pro switches. So when I look at my printer the x is on left side and the y on the back.

    In the config.g file the M574 command is

    ; Endstops
    M574 X1 Y1 Z1 S1
    

    Ok for reasons that I dont understand the homeing process now works as intended. exept for one little detail. it trys to home the z axis with the BL Touch on spot near the x endstop so out of the heated bed. How do I fix this :)?

    The x & y endstop LED is always on when not triggered. I asume that is fine?!
    When Y triggered the LED goes off how ever when X is triggered the LED goes from bright shine to low dimmed but not off. -> is that a problem / do you guys have that behavior as well?
