Enable endstops on a Duex5
-
Currently there isn't a faciliary to reassign endstop connections. This is on the firmware wish list.
-
Ohh, can I use the drivers on Duex as XYZ and get around the problem in that way?
-
Okay, I have pulled 5v from Duex5 and moved the signal to Duet, it lights up but there is no reaction when doing a home… The way I tested it was by doing a safe distance Z home and then putting a screw driver on the sensor. It lights up but does not stop the Z from moving...
Am I missing something?

What commands are you using to home Z?
-
Just the home buttons on the web interface and or Paneldue.

Sorry, mapping drivers does not map endstops.
-
So how can I get past this.. whats the workaround?

Use M119 or the Settings->Machine Properties tab of DWC to test the endstops.
Can you post a link to the datasheet of the endstops, and tell us how you have connected them to the Duet? Does the endstop LEDs on the Duet show the correct endstop state?
-
I took voltage from Duex endstop + & - then I took signal from Duet endstop Z.
When Z is moving I get a led from Sunx when I put a screwdriver on it on Duet Zendstop the led comes on with red light. Z continues to move though.Sunx link http://www.clrwtr.com/PDF/SUNX/SUNX-GL-8U-Proximity-Sensors.pdf
With m119 I get a popup
Endstops - X at min stop. Y at min stop. Z at min stop. Z probe not stopped. -
These end stops are rated 12-24 but works with 5v as they are originals in my printer and runs well with 5 v.
-
any ideas? Some more to test?
-
Which particular model of the GL8 series are they?
-
Hi,
Its a Gl8h top sensing 3 wire model "normally open" -
Have you set up your M574 command and your homez.g and homeall.g files to tell the firmware that you are using an endstop for Z homing? See https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer. Your files may be set up for Z homing using a Z probe instead, depending on where they came from.
-
Well I used the configurator to set it but I will go through it again.
Just to be on the safe side.. I connected black signal cable to the outer pin closest to usb port on Duet. Looking at schematics for Duet it looks like it should be the other way around.. but if I do that I get no led light on Duet.On Duet I have + brown cable and - blue cable.
-
Can confirm the wrong in the schematics now, just measured it and power is wrong in the Duet schematic.

I have M574 X1 Y1 Z1 S0
Had a M558 line active and put a rem in the front now, is that correct to rem that line and use the above for open and low homing?
If so I will test this now. -

Okay I have X homing as it should!
Y is homing in the wrong direction even though I did set it to low. Tried o change it to high incase there was a bug or something but it didnt work… It however stops if I put a screwdriver on the sensor so the sensor is communicating to the board correctly.. Its just the motor homing in the wrong direction despite being configurated as below.
