@knutselsmurf there is no easy fix, because you need two separate UARTs to drive the PanelDue and the Neopixel board, and the only user-accessible UART on Duet WiFi is the one connected to the PanelDue port.

@knutselsmurf said in BTT Smart filament sensor:

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

E15 means that it would take 15mm of filament going through before it takes a single reading which could take some time. Hence the need for calibration.

The calibration will be the same as the Duet magnet sensor AFAIK

@knutselsmurf You can add an external driver board to any of the driver pins on the expansion header (up to 5 additional drivers) or CONN_LCD (2 more). See https://duet3d.dozuki.com/Wiki/Using_external_stepper_motor_drivers#Section_Connecting_Pololu_style_drivers

I recently bought one of these style of boards for a project, which works with stepstick-style drivers (usually A4988 or DRV8825, but you can get TMC drivers that match the stepstick pinout):

If you connect a driver this way, note that all three Z drivers need the same microstepping, acceleration, jerk etc settings, so it may be better to move Z connections onto the Duet, and connect the extruder or other axis to the external driver.

The Duex5 is still current, not obsolete, but may be out of stock where you are looking. It may also be overkill to add 5 drivers when you only need one! Contact info@duet3d.com if you still want one and can't find it anywhere else.

@knutselsmurf said in duetpanel works but touch interface not responding:

PanelDueFirmware-3.3.0-rc2-5.0i-7.0i.bin

I think you may have used the wrong bin file. It looks like you have a 7inch V3 non-integrated.

https://duet3d.dozuki.com/Wiki/PanelDue_Firmware_update#Section_Choosing_the_correct_firmware_binary

Based on that your correct bin file name would be PanelDue-v3-7.0.bin and at this point I would avoid using a release candidate firmware until we get things sorted out.

So the file you would want is this: https://github.com/Duet3D/PanelDueFirmware/releases/download/3.2.11/PanelDueFirmware-v3-7.0.zip

@knutselsmurf said in IR sensor troubles, hotend fan not running too:

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.

adjust with babystepping until its fine. then apply the babystepping to the offset.

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.

what firmware version are you running?
also you dont have a part fan configured. all your fans are Thermostatic control

@knutselsmurf said in Hotend FAN issue:

; Tools
M563 P0 S"Extruder0" D1 H1 F1:0 ; define tool 0

You've assigned fans 1 and 0 as part cooling fans for both tools, but your fans are configured as thermostatically controlled.

It's best to have fan0 as the part cooling fan and fan1 as the hotend fan. fan2 can be whatever you want.

Here's an example.

; Fans M950 F0 C"out3" Q500 ; create fan 0 on pin out3 and set its frequency M106 P0 C"PartCool" S0 H-1 ; set fan 0 name and value. Thermostatic control is turned off M950 F1 C"out4" Q500 ; create fan 1 on pin out4 and set its frequency M106 P1 C"HotEnd" S1 H1:0 T45 ; set fan 1 name and value. Thermostatic control is turned on M950 F2 C"out5" Q500 ; create fan 2 on pin out5 and set its frequency M106 P2 C"CaseFan" S1 H1:0 T45 ; set fan 2 name and value. Thermostatic control is turned on M950 F3 C"out6" Q500 ; create fan 3 on pin out6 and set its frequency M106 P3 C"LEDs" S1 H-1 ; set fan 3 name and value. Thermostatic control is turned off ; Tools M563 P0 S"HotEnd" D0 H1 F0 ; 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

yes see

@Veti yes. I understood that high impendance will not work and there must be 1M resistor in parallel. But I have already switched to regular 100K Epcos and do not want to play with thermistors again without any success that others achieved. Just curious.

But you're saying it already does a purge for the first tool. What exactly is it doing and when is it doing it? Slicer start gcode? If it's already doing what you want at some point you just need to find where that gcode is so it can be reused/adapted to your other tool and probably moved into the tool change files since it would need to happen when going between t0 and t1 and t1 and t0 again and not just once at the start of a the print.

Reduce the P value in your G31 statement so that it is closer to the resting z-probe value (491).

You may need to experiment with how tight the four assembly screws are, if they're too tight the probe will be less sensitive.

To avoid false triggers reduce acceleration and jerk during probing.

the semitec values are B4725 C7.06e-8

@knutselsmurf You can get an idea of what the maximum speed for your motors should be by using the EMF calculator here: https://www.reprapfirmware.org/

Which Duet board do you have? What is the supply voltage? Microstepping should be set to x16 with interpolation, at least to start with. Steps per mm will depend on your belts. Motor current should be set, at maximum, to 85% of rated motor current (if you have 2A motors, 1.6A will be fine). This should give you a maximum speed and step rate from the calculator, and make sure you do not exceed back EMF limits.

Acceleration is more difficult, as it will depend on the weight of the axes, friction and so on, before acceleration causes missed steps. Once everything else is set, start will low acceleration, and increase it until either the motor misses steps, or you are happy. Be aware that very high acceleration will cause backlash/ringing even if the motors can cope with it, due to other limitations in the physical build.

Fixed, the new config file was not uploaded to the sdcard 😀

Hi Arthur,

I'm sorry to hear that your Duet WiFi has a fault. We ship a lot of Duet WiFis and unfortunately a small number of them pass all our tests (including of course the stepper driver tests) but subsequently suffer an infant mortality failure of a stepper driver chip. This is not completely surprising, because we ship boards using several thousands of these chips every month.

If it is a genuine UK-manufactured Duet, it is covered by the warranty that we provide; in which case, please contact your supplier and refer them to this response for authorisation to replace your Duet under warranty.
