@T3P3Tony I'm not feeling temperature difference. Once my current print is complete I'll pull the sensor apart and ensure everything is correct.

Am I correct that there is not way to see filament monitor readings without running a print?

@fractalengineer I saw your post yesterday and the design certainly caught my eye. If the filament monitor doesn't pan out for me I was thinking about doing something similar with an E3D or bondtech hob. Do you think your seeing slip on your printed wheel? Or do you think print variation on your encoder disk could cause distance between pulses to inconsistent?

@I_Jedi

I found that the 5V signal to the BL touch was not instance on, but instead "slowly" ramping up to 5V. The BL touch was not seeing 5V fast enough and going in to error. I added a time relay to create a slight delay before powering the bl touch and it remedied my situation.

@phaedrux

I had thought to do that as well. Just seemed like odd behavior.

I expected the s1 to signify only while printing. If there are retracts and moves it would make no sense to check it on power up.

@dc42

I am not using the M911, due to the bed adhesions issues that will arise as thing cool and the challenges associated with restarting your print. But that may be a viable option to use as an alert. Wasn't sure if there was some other command I was overlooking.

I'll play around with that. Thank you for the quick response.

@Phaedrux

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?

@fcwilt @I_Jedi @oozeBot

I had found that after machine power up the bl touch would immediately run its self test and begin to flash. If I disconnected power to the bl touch then reconnect it would run its self test and complete the test without issue. This worked 100% of the time. This lead me to connect a scope my cheap 24v to 5V power converter and found that the 5V was a gradual increase instead of an instant on.

I tried utilizing the reset command but did not have consistent luck. I believe that reset is only intended for probe up/down failures, not power alarms. Would be great if BL touch offered an up/down/error outputs. Would also be nice if you could actual see the blue indicator light.

@Phaedrux

I will do some additional testing with the same duex2 and advise. I will then reach out to filastruder if needed for a return.

@Phaedrux

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.

bump

I still have not figured out how to utilize the extra end stops on the Duex 2.

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.

@fcwilt

Yes i have a unique trigger file for each.
