Duex2 Enstops
-
I am trying to utilize end stop E2-E5 on a Duex2 V1.0 for external switches. I have this paired with a duet wifi running firmware 2.05.1. E2 and E3 work as expected but I am unable to get E4 and E5 to function. Indicator lights and voltages are as expected, but the firmware appears to be ignoring them. In the rev notes it mentions that Duex2 V0.8a and later can accommodate 5 additional enstops.
Is there an additional lines I need in my config file to assign a trigger to E4-E6?

Hi,
Post the gcode you are using to connect the endstops to the triggers.
You can use the </> icon for entering code.

I have the following triggers set up. Everything works as expected except E4. If I switch the sensors plugged into E3 and E4, E4 continues to not trigger.

Do you have trigger files for each of those numbers?

Yes i have a unique trigger file for each.

Replaced the Duex 2 with a Duex 5 and it apears to now work correctly.
Maybe some one with more knowledge of the firmware can confirm but i suspect that the Duex2 does not have the E4-E6 configured out of the box.

I still have not figured out how to utilize the extra end stops on the Duex 2.
-
Hi,
I cannot help you because I only have Duex5 boards.
If the Duex2 boards actually have 5 functioning end stop inputs they ought to work just like the Duex5.

Hi, can you send M122 with the Duex2 connected?
When you say indicated lights and voltages are as expected, what do you mean exactly?
Do the endstop lights change when the switches are triggered?
How is the Duex wired to the Duet?
Also post your entire config.g.
Are these new boards?
-
Sorry for the delay in responding.
The indicator lights change as expected when triggered. I measured the voltage in each trigger circuit and they measure as expected.
The Duex is connected to the Duet with the supplied 50 pin ribbon cable.
As mentioned I installed a Duex 5 without making changes and everything worked as expected.

@Eduma There doesn't seem to be any configuration reason why the Duex5 would work, and not the Duex2. Therefore if this is a genuine Duet board purchased from an authorized reseller within the last 6 months, I authorize a warranty exchange. Please contact your seller and initiate a warranty claim. Include a link to this forum thread.

Curious if the Duex 2 endstops function as actual endstops for an axis.
-
I will do some additional testing with the same duex2 and advise. I will then reach out to filastruder if needed for a return.
-
I tried to trigger E4-E6 on a separate Duex2 in a different machine and it will not trigger. I suspect that the firmware is not looking at the input since there is no stepper drive at these postions.
Am I correct that in firmware 2.x you can not remap a home sensor to a different axis?
-
Thanks for testing. It would then appear that it's not a hardware issue at all.

Kind of, but I don't think it affects their usage as triggers.
Using M584 to map drivers to axes does not affect endstop inputs. In RRF2, endstop inputs XYZ are pre-allocated, after that they are allocated in the order in which axes are created. So if you create just one extra axes (e.g. U), it will use the E0 endstop input. If more than one axis is created in a single M584 command, endstop inputs are allocated to the new axes in axis creation order (see previous item). For example, M584 C5 U6 would allocate endstop input E0 to the U axis and E1 to the C axis.
RRF3 does have more flexibility in how things are mapped, so if you wanted to test, you could create a very basic config using the online configurator for RRF3, update your firmware to 3.0 and then 3.1.1 and test your triggers. If it works, then you could migrate over, if it doesn't work, then you can reflash to 2.05.1 and use your previous config if you wish.
I'll ask DC42 again about the Duex2 endstops being used as triggers.
