Optical Endstops

Adamfilip

Using Duet2Wifi and Duex5 expansion

I have Dual Optical Endtops on Y axis (Dual motor Y)
and Single Optical Endstop on X axis

; Endstops
M574 X2 S1 P"xstop" ; X max active high endstop switch
M574 Y2 S1 P"ystop+e6stop" ; Dual Y Optical endstops

Motor Map
M584 X0 Y1:9 Z5:6:7:8 E3 ; MOTOR MAPPING WITH 4 Z STEPPERS dual y

I keep getting failed to enable endstops
lights stays on all the time. except when triggered.

I am not sure if the optical switches are 3.3 or 5v.. cant tell
is there a specific model of 3.3v optical endstop i should use. just using some i found on amazon

@Adamfilip

Can you link the exact end stops you have wired up? Also a picture or diagram of you wiring would help.

Here is my first guess. You may be using the wrong type of end stop or need to enable a pull up resistor to get them to work properly. The end stop input pins need to be pulled to ground in order to trigger.

@Alex-cr these are the ones
6PCS Optical Endstop Light Control Limit Switch for RAMPS 1.4 Board 3D Printers Parts with 3 Pin Cable Accessories https://a.co/d/123OLTb

I will draw up a wiring diagram tomorrow

Please post your full config.g and your homing files.
Also the output of sending M122 and M98 P"config.g"

dc42

@Adamfilip if they are compatible with RAMPS then they are designed for 5V. You can convert them to 3.3V if you identify the LED series resistor and solder a lower value resistor on top of it. See https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_endstops#h-33v-compatible-optical-endstop.

Adamfilip

@dc42 the resistors on the sensor are so small and my skills with a soldering iron arent great. I dont think I would be able. to do. thats why I wondering where I can buy a 3.3v one ready to go. wish Duet made one TBH that was plug and play.

@Adamfilip here is my crude wiring diagram lol

@Adamfilip it is the resistor marked 181 that is too high a value for 3.3V. The good news is that you don't need to remove it (which is tricky), you can solder a 180 or 220 ohm resistor of the same size (probably 0603) on top of it, so that the two resistors are in parallel and make about 100 ohms.

Alternatively, if your Duet 2 is a sufficiently recent version, you can provide 5V power to those endstops as explained in the link that I posted.

5V endstops sometimes do work on 3.3V, so it's worth using M119 or the Object Model Viewer in DWC to test whether they are working.

Adamfilip

@Herve_Smith 6 for $13 in US or 1 for $28 in Canada lol

Adamfilip

@dc42 So if i manage to solder on a 220ohm resister like this. it should work.

Adamfilip

@dc42 I can pickup some of these. but cant tell if they will work 3.3

@Adamfilip said in Optical Endstops:

Error: Unknown pin name 'e6stop'

Where is it actually connected?

Adamfilip

@Phaedrux duex5 e6stop

Phaedrux

Change your pin name to duex.e6stop

https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/DueX2_and_DueX5#pin-names

Adamfilip

@Phaedrux Amazing thank you! that fixed it all. its all homing properly now. im shocked to be honest.

I am curious why you need to add duex before e6stop but not when declaring the drive number on duex with M584
