Filament sensor switch in 4 axis Delta

Can you send M115 to confirm what firmware version you have? It should be 3.1.1, if not, you should update.

Here are your endstop pin name options to use in M591 for the filament sensor:

Endstop inputs

xstop
ystop
zstop
e0stop
e1stop
exp.e2stop, exp.4
exp.e3stop, exp.9, duex.cs6
exp.e4stop, exp.14, duex.cs7
exp.e5stop, exp.19, duex.cs8
exp.e6stop, exp.24
duex.e2stop
duex.e3stop
duex.e4stop
duex.e5stop
duex.e6stop

https://duet3d.dozuki.com/Wiki/Gcode#Section_M591_Configure_filament_sensing

In your config.g you have this: M591 D5 C3 P1 E6.0 but that's not going to work in RRF3. C needs to be the pin name you're using.

Can you send M98 P"config.g"? I think you'll see a few error messages pop up.

Thanks for the help.
Yes, my firmware was 3.0 and i uploaded to 3.1.1 but i had some trouble after doing so.
now the screen shows "connecting" the whole time and it doesn´t work .
from the duet web control it works normal.
this is what popped out when i send the comand you asked me to send:

this is what shows now sending m115:

i don´t know why but an error pops out when i try to update duetwificonbined.bin
i updated duet2and3firmware3.1.1.zip and worked.

For the PanelDue you'll need to add M575 P1 B57600 S1 to your config.g

@ander said in Filament sensor switch in 4 axis Delta:

Error: Z axis maximum must be greater than minimum

; Axis Limits
M208 Z-2 U1000 S0 ; set minimum Z

M208 S0 sets the maximum. So Z max of -2 makes no sense.

I guess it doesn't like your D value, which is for the extruder number. And you don't have 5 of them, so should probably change that to 0.

Warning: Macro file config-override.g not found

That just means you haven't used M500 yet to create the config-override.g file, but you do have M501 at the end of config.g to load it if you did. If you do a PID tuning of your heaters and send M500 it will save the results to config-override.g and then M501 will load them at boot.

Uploading the complete zip file as is without extracting it is the correct way to do it.

Thanks for the help.
The screen now works thanks to your advice
the filament sensor value is changed to 0 and is not giving any error but i don´t know yet if works properly (how can i check that?)
the macro error....you were right, i didn´t send the m500 yet because i just put a new duet and i´m trying to put it to work.
I changed the z -2 to z0 and i still have the same error.
this is what i see now after sending M98 P"config.g"

you have no maximum defined for all axis

you have no minimum defined for x and y

your thermistor config is wrong. find the correct beta value in your thermistor documentation.

M591 D0 CE2_STOP P1 E6.0 ; filament monitor connected to E2 endstop

that command seems wrong the pin definition is wrong and does not exist

That's normal when the printer is a delta.

M591 D0 CE2_STOP P1 E6.0 ; filament monitor connected to E2 endstop

that command seems wrong the pin definition is wrong and does not exist

yes indeed, the pin name needs to be enclosed in quotes like this:

M591 D0 C"E2_STOP" P1 E6.0 ; filament monitor connected to E2 endstop

missed that part. thx

but whats the error then?

Error: Z axis maximum must be greater than minimum

He's still using M208 S0, which is the maximum, but he went from -2 as the max height to 0 as the max height. Still makes no sense.

@ander Use M208 S1 Z-2 That sets the low point of the z axis to -2mm below the surface. You'll need a separate line for M208 S0 U1000 to set the max travel for your U axis

Thanks for the help, i tried what you (phaedrux) sayd and worked, i don´t have this error anymore.
Now, the filament sensor switch (it is a regular endstop switch)is connected to pin 4 (E2_stop)in the expansion board.
and is giving me an error:

M98 P"config.g"

How can i make it work?
here is my last config.g
thanks

thats the wrong name. phaedrux posted a list of the pin names that are valid in this thread

Phaedrux · 20 Oct 2020, 17:23

@ander said in Filament sensor switch in 4 axis Delta:

Error: Unknown pin name 'e2stop'

Try exp.e2stop as the pin name.

ander · 3 Nov 2020, 17:26

Hi there
i put exp.e2stop, and my endswitch´s signal wire goes to pin 4 on the expansion side, i see no error for now when i reset the duet. then i tested printing something and pushing and releasing the switch of the filament....the printing continues as normal....so it doesn´t work.
Also, something weird happens with the extruder that i realised. If i set manually for example 200 degrees for the extruder, seems to reach and mantain it very well. but when printing....first reaches 200 degres and then starts autoleveling...and when does it, temperature varies quite a bit, and sometimes gives me temp error due to those oscilations (i´m using a E3D)
thanks

Anyone can help me please?

Phaedrux · 3 Nov 2020, 17:25

Sorry I missed your last reply there.

M591 D0 C"exp.e2_stop" P1 E6.0

The underscore shouldn't matter, but try remove the _ between e2 and stop.

The E6 parameter would only be used with the laser monitor. This is a simple switch is it not? So remove the E6 entirely.

You're also missing S1 to enable filament monitoring.

Try this corrected line

M591 D0 C"exp.e2stop" P1 S1

The other alternative is to try enabling pullup resistor by adding a ^ in front of the pin name.

M591 D0 C"^exp.e2stop" P1 S1

If that doesn't work, you can also try P2 instead of P1. I'm not sure what type of switch you have, so try both.

Have you done a PID tuning of the hotend yet? Do you have a silicone sock on the nozzle? Does the part cooling fan blow on the heater block?

ander · 5 Nov 2020, 08:38

Hi there
Yes, i already did the PID tunning, i have an E3D with a sock, but the weird thing is that the malfunction happens only while autoleveling, if there is no temp error after autoleveling the printing goes perfect, the temperature is very stable.
referring to the filament monitoring, i tried like you said and looks like works
