How can this be fixed?

Ok, i have a Duex5 also, not used yet.
Is it possible to use the neopixel with this Duex5 board?

I have bought Fysetc neopixel board, there is a problem with it: It works only when i switch on the printer with neopixel disconnected, as soon the paneldue got a successful connection with the duet2wifi board i must attach the neopixel board too: then everything is working nice. But when i start the printer with paneldue and neopixel board already connected, the neopixel board works but the paneldue shows only the dashboard but the paneldue can’t connected with the duet2wifi.
If i only connected the paneldue and powered it on: paneldue works as it should be. Same when i only connect the neopixel board: neopixel board works nice.
Used the latest reprap firmware for the duet2wifi and the paneldue (both original Duet).
Tested many times now: when NEOPIXEL and PANELDUE v3.0 are both connected: only NEOPIXEL works as it should be, the PANELDUE show the interface but can't connect...

Any idea what’s wrong and how to fix this?

Hi!
I have a BTT Smart filament sensor and I am trying to understand how it works.
Seems to be working but still have questions:

when I do a sensor calibration, I get these results:

7-8-2021 19:46:18 M591 D0 ; display filament sensor parameters for extruder drive 0
Pulse-type filament monitor on pin e0stop, disabled, sensitivity 0.500mm/pulse, allowed movement 90% to 110%, check every 3.0mm, measured sensitivity 9.165mm/pulse, measured minimum 0%, maximum 17% over 2089.7mm

7-8-2021 18:30:53 M98 P"0:/macros/Filament/Filament sensor tuning"
Pulse-type filament monitor on pin e0stop, disabled, sensitivity 0.500mm/pulse, allowed movement 90% to 110%, check every 3.0mm, measured sensitivity 12.023mm/pulse, measured minimum 0%, maximum 16% over 96.2mm

So, what is now the best setting for M591 ?
Now, I have this:

M591 D0 P7 C"e0stop" L0.5 R90:110 E3 S0

something else, when I enable the sensor, and start a print and remove the filament after some printing time, the printer is not paused?
this was tested when I had this (not calibrated yet: ;M591 D0 P7 C"e0stop" L7 R50:200 E15 S1 ;configure BTT smart filament sensor

Any help would be nice

Hello,

I build a BLV printer and I have a Duet2 WIFI board, software uptodate.
I have a dual independed Z-motor system, works great!

BUT: I would like to add a 3th Z-Motor (it's a huge printer with a large bead) to improve it.

How can I do this? The Duet2 expansion board is out of stock (obsolete I think)..

@nurgelrot
I have flashed the 7" screen now with PanelDueFirmware-3.3.0-rc2-5.0i-7.0i.bin via USB and Bossa.

After resetting: no working touch.
Again poweroff, resetting: working touchscreen ?!

So, I have connected the PanelDue to my Duet2Wifi again (4 wires), screen comes alive but no working touch screen.
After a while, screen is getting dark: a reset and it's back.

Really don't understand what's wrong...

This is my screen:

Is it damaged ?? Weird, it worked perfect with the old firmware in the Duet2Wifi..

Any help would be great!

@phaedrux can't see that!
this is what the screen shows me:

Will try to update the firmware directly using USB on the DuetScreen board

Hi,
I have a DUET2WIFI and a DUETPANEL 7" : the DUETPANEL shows the interface but when I press the touchscreen nothing happens.

Details: Duet Web Control 3.3.0
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.3 (2021-06-15)
Duet WiFi Server Version: 1.26

Bellow my my config.g.

Checked the wiring, everything looks ok.
Before the firmware update the touchscreen worked..

I hope somebody can tell me how to fix this...

Would be great!

I am testing the IR-sensor, it works but I can't print..

2 issues:

after calibrating (using the method from https://miscsolutions.wordpress.com/mini-height-sensor-board/, I started a testprint. When it starts the bed is raised too high: the melted filament can't get out the hotend and after some time the tube-clamp is pushed out the top of the hotend.
something else: when the hotend is heated up, the hotend FAN is not running: I can start it by moving the fan-slider in the duet browser panel, but that is not what we want ofcourse.

Below my configuration, I have used the webbased configtool but it looks it's not making the right configuration (ofcourse, I loaded the zip-file when it was ready with the configuration..)

Maybe the IR-sensor is not a good idea to use ? (I have the orginal dc24).

I hope somebody can help.

Many thanks in advance!

Regards,

Arthur

I have a DUET WIFI, 1 hotend with fan and a objectblower with 2 fans.

Hotend fan connected to PWM Fan0, objectblower-fans connected (parallel) to PWM Fan1.

I want to have it tempered controlled: hotend above 45 -> fan0 must be activated on 80%.
Object fans only running when needed (depending of the print object.

What I see now in the Duet Screen: a FAN-controller for the hotend which I can move from 0 to max ?? This is only handy for the object-fans, the hotend fan must not be controlled via the duet panel. Tried different things but I can't see whats wrong.

Below what I have in the config.g file for these items.

I hope somebody can se whats wrong and can help me with this.

Would be great !

I want to disable the power as soon as the printing is ended and the hotend and bed has cooled down enough. I have a Duet Wifi.

Best way is to have a total power down, no standbye mode.

I am thinking of usuage of a SSR or better: by sending a MQTT message to a MQTT-server.
I have a Tuya smartpower plug (with tasmota firmware, working with mqtt).

Is this possible with the expensive Duet Wifi board ?
Or any other tricks to do this?

I found this: https://forum.duet3d.com/topic/8310/automatic-power-supply-management/4?_=1610304671322

Maybe you can correct/add it for me, I really don't know how to fix this

The above free* and post* files is a copy of another guy with a multi-extruder setup.
Don't think this is ok for me, but for starters..

Printing with just 1 color is ok now..

But: I want to print a dual-color print.

I have followed the things above but it still doesn't work ok.

First extruder 1 is selected, printer purge the hotend and after that it start printing.
Then the 2nd color is needed, selection of the 2nd extruder goes well but it must purge first before it can continue printing. Same thing as soon as the 1st extruder is needed for printing.

How must this be done ?

Problem with the heater is fixed: replaced thermistor and heater, SliceEngineering tools now installed..

I have a Mellow 450'C thermistor with these RT-table:

According the seller it's thermistor 66 in Marlin, tried that but it gives the wrong temperatures.. Same thing in the BLV (Duet-reprap), other settings..

For RepRap and Marlin we need some parameters like the ADC-values, the beta and more..

Can somebody explain how we can calculate this with this Mellow 450'C thermistor as example ?

(I want to use this thermistor on my Ender5 (Marlin) and on my BLV (Duet-Reprap)).

I have done some tests (without gcode print job): when I just heat up the hotend (tool0 is selected on startup) and I purge some filament it works nice. When I click on tool1 then the filament of tool0 is retracted 25mm, after that, tool1 moves 25mm filament.
When I repeat the selection of both tools a few times, it works but after some time the hotend stops heating.... Active heater setup is changed to 0 also..

I get an error after some attemps too:
"T0 Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault"
But that's logic, the hotend is switched off...

So, I hope somebody can help with this...

Dual-color Print job started: printer starts but the nozzle-heater stops heating after a short moment. No errors...

Any idea?
