    • RE: heatsink for watercooled hotend, dimensions?

      Sorry for answering to this old post. And this is only for info:
      I have finished the work on my prototype watercooled hotend. Now it's ready to make first tests...
      The heating block and heatbreak is from a DTO hotend.

      Here are some images

    • RE: Part cooling fan not strong enough

      @andreic I think your ducts produces to much back pressure. You should test the fan in "free air" for comparison...

    • RE: Small UI BUG

      @tinchus I think you can solve the problem with putting an ";E" after the comment semi-colon, like this:
      G1 Z400 ;E drop the print bed (E to exclude from layer count)

      (Obviously, you need to be in absolute positioning mode for this to work)

    • RE: is a delayed triggering of the filament sensor possible?

      @cr3d I don't know which macro is called when the filament out sensor triggers...
      But in that macro you can "store" the actual Extruder Value in a variable, make your math, and call another macro after 50cm of extruding.
      Eventually is daemon.g also a good option to put the code in...

    • RE: Thermostatically-controlled fan

      @agusano Which FW Version are you using?

      Eventually you can invert it with a leading "!" in the M950 command

      M950 F2 C"!Fan2" Q25000

    • RE: Precision Piezo Orion what material its better for clamp?

      @peirof @engikeneer ASA is more or less like ABS. It's really good for outdoor usage, because of very good uv-stability. The max temp is approx. 90-95°C
      Small parts are no problem to print without warping. For big objects a (heated) chamber will help.

    • RE: DWC Custom Configuration

      @dr_ju_ju said in DWC Custom Configuration:

      As I said, I want an EASY way to modify the pages, without reverting to code bashing !!

      Perhaps the BtnCmd PlugIn is something for you?
      https://forum.duet3d.com/topic/22776/btncmd-dwc-plugin-create-custom-layouts-action-buttons
      An easy way to create individual tabs inside DWC. All object based, with very less coding. At the moment i use 3 tabs:
      One tab for preheating, homing/leveling, important infos:
      cosmoTAB.png

      the second for endstop status, spezial functions, links
      setupTAB.png

      the third tab will soon be used for FW retract tuning:

      @mikeabuilder said in Bainbridge BARN Mark4:

      but we're thinking of moving it to a location under the printing zone

      try to install the electronics with good accessibility... it's much easier to make changes or checking some things.

    • RE: How to run a gcode loop X times

      @code7 where would you like to do the loop?
      in a print file or in a macro?

      EDIT:
      If it is in a macro then something like this:

      while iterations < X
          your gcode

    • Duet2, controlling more fans

      I'd like to ask if it is possible to connect a pwm mosfet module to a free heater pin on the expansion connector for controlling more fans?
      The pwm module looks like this and it is for 3.3VDC input:

      Do i need some "special wiring" like a fuse or diode somewhere to protect the duet?

    • RE: Mushrooming print - What could cause this?

      @leav
      Are you shure that your delta is built correctly?
      bed in right angle to the towers, rod length, radius, ...

      I think, some wrong parameters/dimensions can cause this "mushrooming".

      EDIT: can it be that the effector is tilting?

      @ratrig0331 if you define your output with a M106, you can set the max. speed with the X parameter.

    • RE: heatsink for watercooled hotend, dimensions?

      @norder Yes. You're right. It would be better to place the in/outlet on opposite sides. But i haven't the space for that.
      I don't have "bridge" between the ports. But i'm sure, the cooling will be sufficient.

    • RE: heatsink for watercooled hotend, dimensions?

      @mandragora said in heatsink for watercooled hotend, dimensions?:

      Are those brass barbs custom or off the shelf?

      They are more like custom. They were used as gearbox ventilation fitting in an old f1 car.
      I have glued them in a carbon tube. They're from nitrated titanium, very light.
      I try to reduce wheight on my effector (Delta).

    • RE: What's wrong with my code?

      @owend
      I've found the error in my start.g, where i set the variable to 0.
      Sorry for that!

    • What's wrong with my code?

      I have the following definition of variables in config.g:

      ; AutoFanOff Feature 
      global EnableAutoFanOff = false	; create variable for enable/disable automatic fan shut off
      global StartTimeAutoFanOff = state.upTime	; create variable for cache the fan start time
      global DurationAutoFanOff = 240		; create variable for AutoFanOff duration
      
      
      

      Then in daemon.g i have:

      ; daemon.g  
      ; frequently called routine (0.1 Hz)
      ; used for checking AutoFanOff Feature
      
      ; AutoFanOff (some routines switch the layer fan on for faster cooldown. this code checks if it is time to shut down the fan)
      if global.EnableAutoFanOff = true	; check if automatic fan shut down is activated
      	if state.upTime > {global.StartTimeAutoFanOff + global.DurationAutoFanOff}  ; check if the fan was running for the desired time
      		M106 P0 S0		; LayerFan off
      		M291 P"AutoFanOff has stopped fan!" R"daemon.g" S0 T5    ; message
      		set global.EnableAutoFanOff = false	; disable automatic fan shut off
      

      When i run this config i get the following error:

      Error: in file macro line 6 column 46: meta command: cannot convert operands to same type
      

      Is it possible, that the variable set in config.g (global EnableAutoFanOff = false) is not a boolean?

    • Z-seam for PA tuning

      I use Cura4.8 and i'd like to print a 100mm cube for PA tuning.
      But i struggle to positioning the z-seam to the front!?

      I have positioned the z-seam and also layer start point in front. But cura does it always in the corner!?
      Does somebody know why?

      Thanks in advance
