Last try. CR-10 v2 help



  • I have the stock board out of my cr-10 v2 and have a couple of questions as I begin to re-plug everything in. There are two main cable bundles going to the board…one with a large multi plug end and the other a bit smaller. Here is how the bundles are laid out…

    Small end:
    Y Motor (4 wires)
    Z Motor (4 wires)
    Z Motor (4 wires)
    Z Limit (2 wires)
    Y Limit (2 wires)

    Large end:
    E Motor (4 wires)
    X Motor (4 wires)
    X Limit (3 wires)
    X Limit (2 wires)
    Z Limit (3 wires)
    Thermistor (2 wires)
    Fan (2 wires)
    K-Fan (1 wire (in two wire plug)
    D11 (1 wire (in one wire plug)
    A power plug with red and black conductors

    I am assuming the two limit switches for each axis represents a high and low stop. Which plug (2 or 3 pin) is the high and which is the low? Do I have to plug both into the DW2 or just one set? If so, which ones (2pin or 3 pin)? I am assuming that the BL Touch plugs in exactly like it did for the Ender 3. There is only one thermistor plug. I’m assuming it is a hot end. Not sure what to do with the “K-Fan” with one wire in a two wire plug as well as not knowing what to do with the D11.

    I appreciate any help someone could give. I’ve searched through the archives and couldn’t find anything that makes sense to me. If there is something there, I am using the wrong words.

    Thanks again for any help!

    There is no set standard to answer from. A multimeter to measure and manually actuating the end stops might be the fastest way to determine.

    If the wires are colour coded maybe some up close pictures will allow someone to make an educated guess.



  • Thanks! They are just standard Creality black. Regarding the multitester, would I just use the continuity setting with opening and closing the circuit with the end stop?

    Thanks again!

    yeah, that will work on normal mechanical endstops, (ideally it'll beep when the switch is not triggered and stop beeping when you trigger it)

    (pictures may facilitate some educated guesswork in any case ; especially with respect to any reason to prefer one over the other end stop as you will (and can) only use one)

    The CR10 is almost identical to the Ender 3, so maybe this guide will help? The Maestro is a bit different than the Wifi as well, but might get you on the right track.

    Multimeter is your friend. Pictures help if you have specific questions.



  • @bearer

    The 2pin limit switches (x&y) should be the endstops as I put the tester on them and they stop beeping when I trigger the physical endstop switch. I am assuming that I don't use the 3 pin plugs. Thanks @bearer!



  • Sounds reasonable; should wire the switches to the two outer most pins on the Duet and set it up as normally closed / active high / S1; and choose low or high end according to where they're placed relative to the coordinate system.

    (Btw I'm guessing D11 is a PWM enabled pin that gets used for BL touch / lasers / etc if fitted to the other end of the bundle.)



  • @bearer

    I actually had some spare Duet ends to rewire the end stops and I bet you are right on the D11.

    Thanks again!
