Hall Sensor Help

I currently am trying to set up some hall Sensor boards, they say they are rated for 3.3V and 5V and come with a potentiometer. When activated the active light on the endstop goes away and the triggered light on the duet lights up but there is no firmware signal in settings or M119 of the endstop being triggered. In fact when I even try to home it says endstop failed or not recognized, I don't remember. Is there any way to fix this such as a resistor or would it be best to get new sensors? If so which ones would be guaranteed to work?

Looking closer it says that the sensor itself is rated for 5V....

Is there any way to modify them to work or are there any recommendations?

its helpfull to post the actual error message.

post your config.g and a picture of your wiring

koaldesigns

When pulling up the M119 command, this is what shows:

Endstops - X: no endstop, Y: no endstop, Z: no endstop, Z probe: at min stop

When I try homing:

G1 H1 X-20 F100
Error: Failed to enable endstops

And here is my config.g

My wiring is as it states, signal to signal, ground to ground, and Vcc to Vcc

this disables all endstops. so the duet is doing exactly what you are telling it to do.

koaldesigns

So I'm just an idiot, nice....

M350 X128 Y128 Z16 E16:16 I1 ; Set 16x microstepping with interpolation

the duet 2 does not allow interpolation at anything else that x16. so this wont work.

Does this check out?

Veti

if thats your entire config. its missing a lot.

tool, hotend, heater etc..

@Veti No, its just the movement section

Currently I am only trying to get movement and homing to work so the rest doesn't really matter to me right now.

Veti

on a side note.
since you are setting up the printer from scratch, it would be best to start with version 3 of the firmware.

not much point investing time with version 2 and then having to invest time again to update to version 3.

koaldesigns

Yeah probably a good idea, I haven't found any SCARA configs for version 3 yet so I may delve into that later today. I need to compile a custom version of it though due to a non-standard kinematic as I have a 3rd rotational axis on the arm.
