Duex5 E stop headers not working

Alijambo73

Is it not possible to connect more than 1 runout sensor too the duex 5 e stop headers? If I connect one sensor to any of the headers everything is OK but when I connect 2 the board seems to not boot and wifi does not work.

I am trying to use the E2 AND E3 headers.

Any help would be appreciated.

Do both sensors work individually when connected alone, and on either header?

Alijambo73

@phaedrux yes. Either sensor would work on either header as long as there was only 1 connected at a time.

Phaedrux

What kind of sensor are they?
Can you show the wiring?
How are they configured?
Firmware version?

@phaedrux They are just simple sensors.

; Filament Run-Out
M591 D0 P2 C"e0stop" S1 ; E-0 watcher Filament run-out sensor triggers a pause
M591 D1 P2 C"e1stop" S1 ; E-1 watcher Filament run-out sensor triggers a pause
;M591 D2 P2 C"exp.e2stop" S1 ; E-2 watcher Filament run-out sensor triggers a pause
;M591 D3 P2 C"exp.e3stop" S1 ; E-3 watcher Filament run-out sensor triggers a pause

The duet will not start correctly and does not have any wifi connection when both are connected. If I connect them to the duet board in place of the other 2 everything is ok. So it seems sensors are wired correctly.

I see your endstop voltage select jumper is at 3.3v. I still don't know anything about your sensors, but perhaps 5v would be better?

And your pin names should be duex.e3stop, etc

@phaedrux I didn't change a thing and all of the sudden it all seems to be OK. I have been trying to figure this out for 2 weeks now.

One other question, If any of the sensors do not detect filament it will pause printing even if it is only using 1 extruder. Is there a way to configure it so that only the sensor on the extruder being used will trigger the pause?

I have to disable each sensor or put a piece of filament in each sensor even to print 1 color.

I changed the names for the 3rd and 4th sensors.

; Filament Run-Out
M591 D0 P2 C"e0stop" S1 ; E-0 watcher Filament run-out sensor triggers a pause
M591 D1 P2 C"e1stop" S1 ; E-1 watcher Filament run-out sensor triggers a pause
M591 D2 P2 C"duex.e2stop" S1 ; E-2 watcher Filament run-out sensor triggers a pause
M591 D3 P2 C"duex.e3stop" S1 ; E-3 watcher Filament run-out sensor triggers a pause

If you're using tool changes you can disable the sensor in your tpost and only enable it in tpre. That way only the active tool is monitored.

@phaedrux would I use M591 D0 S1 to enable and M591 D0 S0 to disable and would I need to change S1 to SO disable them in config.g?

Shouldn't it be disabled in tfree rather then tpost?

I haven't used these before so I'm tryting to figure it out now. I should have a tfree, tpre and tpost file for each tool correct? I am using a single nozzle with 4 extruders.

Here is what I have for my tfree0.g, tfree1.g, tfree2.g and

M83 ; relative extruder mode
G1 E-150 F300 ; retract 150mm
G1 E-300 F2500 ; retract 300mm

for tpre0.g,

M591 D0 S1

tpre1.g

M591 D1 S1

tpre2.g

M591 D2 S1

tfree3.g

M591 D3 S1

For tpost0.g, tpost1.g, tpost2.g and tpost3.g

M116 P0 ; wait for tool 0 only to reach operating temperature
M83 ; relative extruder mode
G1 E450 F2500 ; undo retraction

Does this look OK?

Do I need to include a tool change script in my slicer (simplify 3d) to run the macros?

Sorry for all of the questions. Thanks
