I have a Tevo Black widow which I just converted over from the MKS Gen V1.4 board to a duet Wifi. Im having all sorts of issues but lets just focus on the endstops. I have gone through the configuration tool a few times and tried different settings but nothing seems to work. I am 99.9% sure that I have the wiring hooked up correctly. When I hit the m119 command I get this: Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stoppedok

The endstops do not seem to light up at any point whether I put something metallic in front of them or not. I would very much appreciate any help someone can offer.
P.S. If you see anything else in the files that looks out of place I would really like the advice.

As this endstop LEDs are never lit, this suggests two possibilities:

1. A wiring error. Note that the order of the 3 endstop pins on the Duet is not the same as on most 8-bit boards.

2. You are supplying the proximity sensors with 3.3V from the endstop connector, but they need 5V to operate.

PS - I suggest you search for "tevo black widow" at [www.duet3d.com] because other people seem to have done this conversion successfully.

Thanks DC42, for the super quick response. I believe I have taken into account the different order of the pins on the duet in comparison to the MKS. ( I will double check to make sure) Is there somewhere else on the Duet that I could connect to in order to get the 5v. I did look at the site you pointed out and researched the TEVO BLACK WIDOW. It talks about connecting a diode? this is getting into some unfamiliar ground for me. I will definitely have to do some more reading. Thanks. P.S. When the Duet is powered up, what lights should all bit lit up on it. I will attach a pic of mine

The red 5V and green 3.3V LEDs should be lit, also the red 5V USB light if it is receiving USB power and the blue LED if it is receiving VIN power. The Diag LED may or may not be lit depending on configuration.

May I suggest that you request an account on the duet3d forum and ask questions there. That forum is a lot more active than this one and has other Duet+Tevo users.

Hi DC42 i tried to register for an account on that site but it stated not accepting any new registrations.

Never mind I see where I can Email to try and get set up.

If you look at the welcome message in the heading, it says to send an email to request an account. Unfortunately we were getting too much automated spam on the forum, so we had to suspend self-registration. We'll be moving to different forum software soon.
