Hi All

I'm really bringing this post back from the dead!
Was there any progression on the use of your non-contact sensor through the Duet system? I am wanting to implement something similar for myself.

Thanks

Hello Droftarts and DC42

Apologies for the long reply. I was not receiving notifications from these posts as I used to and did not see your replies.

; Filament Sensor
; M591 D0 P3 C4 S1 R80:120 L26.32 E3.0                   ; filament sensor for extruder 0, enabled, sensitivity 26.32mm.rev, 80% to 120% tolerance, 3mm detection length

I have not had time to play with the setup any further but from the looks of things, the filament is nicely held in the hobbed groove. I may re-print the housing with our Form 2 SLA printer and see if that helps with the alignment of the idle wheel.

Kind Regards
Benjamin Norton

Is anyone able to weigh in on this issue?

Hi All

I am trying to set up the sensor-less homing on my Duet 2/Duex5 controlled printer and am so far have had some issues in that the bed drives into the ends of the Z-Axis assemblies and skips steps but does not sense them.

I am wanting to use the sensor-less homing to do a 'gross' homing of the ball-screw driven Z-Axis actuators which are prone to falling under the weight of the bed when the motors are idled which leaves the bed on a bad angle. This does not cause any damage as the bed is mounted with ball and socket joints. After this gross homing is completed, the printer will then use the BL-Touch probe and the independently driven Z-Axis actuators to to the more accurate bed levelling (G32).

I have setup a testing macro that is essentially a modified 'homeall' sequence. The G32 would be added in later.

Hi All

Hardware:

Duet 2 Wifi
Titan Aero w/ 1.0mm E3D Nozzle X
Rolling Sensor Rev 1.7 - Mounted to filament pressure lever (picture below)

We have recently purchased a Duet Rolling Magnet Sensor for the intention to use it with 2.85mm filament, mostly 85A Ninjaflex. We have successfully reverse engineered the 1.75mm housing and adapted it to fit the larger filament.
After successfully connecting the sensor to our Duet 2, we have began to receive readings while running test prints which are less than ideal, min 87%, max 113% over 581.2mm, and are hoping to improve upon this. My thinking is that the sensor is trying to measure filament retractions which isn't read accurately with the flexible filament(?). I have calibrated the sensor as accurately as possible.
Has anyone successfully adapted the 1.75mm sensor to fit 2.85mm filament?

Thanks for all of help.

Hi Pheadrux
Yes, it does work from the always on fans and I have tried to adjust the Signal Inversion.
I am starting to think that it is the fan that I am trying to use. It is a Cera Dyna ATX Radial fan.
I will try come different fans and hopefully they will work.
Thanks for the help!

Hi All
Once again, there is another person struggling to configure their Print Cooling Nozzle Fan. I have read all of the other posts regarding this issue but still have not succeeded. I have my nozzle fan connected to Fan0 on my Duet 2 Wifi (2.02 Firmware) and Heatsink fan on Fan1.
So far, I have tried adjusting the blip time, changing the frequency, tried different Fan connections, re configuring tool settings and just about everything else.
I understand that Fan0 is set for PWM on the nozzle fan by default and tried to run the fan with no config settings for it, but I figure it wouldn't hurt to put it back in (whether its a good idea or not).

My Config.g is below:

*; Fans
M106 P0 S1 I0 F500 H-1 B1 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P1 S1 I0 F500 H4 T30:55 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
M106 P6 S1 F500 ; configure fan 6 as always on
M106 P7 S1 F500 ; configure fan 7 as always on

; Tools
M563 P0 S"Nozzle 1" D0 H1 ; Define tool 0
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C*

Thank you all for the help.

Hi Guys
I am wanting to run a Rolling Magnet Filament Monitor with 2.85mm clear TPU filament but I have seen that it is only available for 1.75mm filament. Is there a way this can be done? Is it possible to alter the housing to allow for the larger diameter?

Thanks for all the help

@deckingman
That makes sense now. I just figured each endstop input would pair up with the corresponding motor output and I didn't look too much into it! Thanks for all of the help.

@dc42
I did have the second Y Axis endstop connected to the E4 Endstop input on the Duex Board and not E0. I swapped them over and It seemed to do the job! Why would that be necessary? Wouldn't the endstops be married to their stepper output?
Thank you for all of the help

I still have not been able to solve this one! I have tried a few new things but still no luck
Any help would be appreciated!

@dc42 Thank you for the reply. When I home the Y, only the one motor (Left Side, Y1) spins and it triggered by its own endstop, the Right motor (U7) doesn't spin. It does however rotate about 5deg instantaneously when the left endstop is triggered... Very strange.

Should the motor mapping line look like this:
M584 X0 Y1:7 U7 Z2:5:6 E3:4 P3 ;

Or this?:
M584 X0 Y1:7 U9 Z2:5:6 E3:4 P3 ;

Hi All
My current setup is a Duet 2 Wifi and a Duex5 Board all with the latest firmware. I am running 3 Z-Axis motors, two Y-Axis motors and 1 X-Axis motor.
I am wanting to setup a limit switch for each of the two Y-Axis motors to that they are able to realign the X Gantry during their homing process. I am having troubles and have looked at plenty of pages and forums.

I have managed to get the Y-Axis to home on one of the limit switches so far.
I have setup a dummy axis (U) which is used to separate the two Y-Axis motors during the homey.g process.

My config.g currently is:
