    • Displaying current extrusion volume possible?

      Hi guys,
      I'm playing with my new extruder and would like to know how much it extrudes in a real print.
      Is it possible to display extrusion volume in DWC? Printspeed, layerheight and layerwidth? should be available for calculations.
      I extruded in free air to get ballpark numbers, but real life is different.

    • RE: Music skipping beats after firmware update (3.4.0beta6)

      @gtaman
      It's actually the same:

      • create a global variable blockDaemon
      • set global.blockDaemon = true at the start of the M300 file
      • set global.blockDaemon = false at the end

      Then anyone using Daemon.g for real can add these lines

      while global.blockDaemon = true

      • positive Y goes to the back
      • positive Z goes up

    • RE: External stepper drivers (TB6600) on duet 2 wifi

      @m0ck1nj
      Check the TB6600 datasheet. If it is OK with 3.3V signals on step, dir, enable you can wire it directly.
      If it needs differential signals or 5V you can use the much cheaper expansion breakout board

    • RE: Smart Effector including toolboard-capabilities?

      @dc42 said in Smart Effector including toolboard-capabilities?:

      It's clear to me that the Orbiter could not be used with a Smart Effector made to the current dimensions. We would need to increase the rod spacing to at least 80mm in order to accommodate the various parts of the extruder. We are looking into this, however it would make it unsuitable for the smaller delta printers.

      2020-12-04 14.07.55.jpg

      Hi dc42,
      I just stumbled across this thread and wanted to guide you back to 2016 , when we discussed the cycloidal direct drive. (I still have it laying around)
      I've made an 45 degree adapter for it, that suited the smart effector pretty well.

      Another way to mount it, was the split motor/gearbox idea.

      I could try to reuse my motor and design a BMG-drive for the Smart effector?

      @seventhwhiskey
      With M563 you shouldn't use the real driver numbers for the extruders, but their logical order as they appear in the M584 drive mapping.
      Tool 0 is D0; Tool1 is D1

    • Display current back EMF for tuning

      Hi devs,
      based on the "extrusion volume" thread, I also think a back EMF calculator as DWC plugin would be helpful for tuning.
      The required parameters are almost completely known for the calculation. It only misses coil resistance and inductivity (AFAIK)

      Since my Duet boards run on their own network, I don't have access to the EMF calculator at reprapfirmware.org

      If we could integrate it as plugin and use 'live' values from the current object model/gcode file, we'd have a nice tuning tool

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

      @cr3d
      ...what cosmowave said.
      You can trigger your own filament-out macro with the filament sensor, which in the end toggles a different I/O pin. This pin is the 'official' filament-out pin defined in config.g

    • RE: Software version 3.4.2 now available

      @mikeabuilder said in Software version 3.4.2 now available:

      it's not like Duet3D is getting ripped off by the clone makers. It's one strategy for building market-share

      You are partly right. But there are cloners, who try to cut cost by using less copper or noname headers. Those clones can destroy Duet3Ds reputation and thereby reduce market share.

      My way of supporting Duet3D is to test FW and report/share my findings/ideas regarding new/future usecases.

    • RE: SLS 3D printer

      @SLS-3D This guy {external link} has done it and also links to his sources about error correction.
      He's using a 600Mhz teensy4.0 for it, fed with gcode by an RPi? So the bottleneck doesn't seem to be the stepper speed??

      My impression is, that the stepper might be fast enough, but lacks true resolution. Microstepping isn't as accurate as we wish.
      That's OK for a laser-show, but your SLS printed parts might show some imperfections.

      @Poul-Erik Increase the 'H' parameter in the Z-probe definition until the problem is fixed.

    • RE: Invert Z Controls

      @CthulhuLabs
      See it as distance from bed to nozzle instead. It works in any case.

      Once you've rammed the nozzle into the bed surface (cracking some glass sheet), because you allowed negative Z-range, you'll learn this lesson fast. (I did 😉 )

    • RE: Direction/Velocity Vector of Printhead movement

      @deme said in Direction/Velocity Vector of Printhead movement:

      it would be better to be able to read the queue directly to enable directional in-situ control.

      IMHO to get ahead of the queue, you need to simulate gcode in real time on the Pi and send data to Duet simultaneously.
      IIRC, the simulator plugin currently runs on the Duet, so there is a pile of work to do.
      Using only the accelerometer will fail in the long run, you'd need a 6DOF or even 9DOF sensor fusion ( accel, position, earth-magnet field) like it's used for multicopter heading and mission control (path control)

    • RE: How well does the RPi Zero 2W work with the Duet3 mini5+?

      @0nn0
      I only benchmarked the Z2W and it was on par with RPi3b.
      Without GUI the available memory is suitable for SBC use, I guess.
      Everytime I wanted to test SBC setup for Duets, some threads here told me, it's not worth the extra hassle (yet)
      You'd need a PC to connect remotely to the SBC; no advantage here either.

      It's Q1 that fell off, but C1 is also written close to the pads and can easily lead to confusion.

      @CCS86
      Interesting thread.
      Isn't IS only avoiding acceleration around the resonance frequence, but can accelerate faster than that?
      IMHO it should work smoothly above resonance frequency until you hit double/quad frequency again.

      Maybe define it as a spindle? That way you don't need a temp sensor and can set RPM directly. (as percentage of max RPM)

    • RE: Issue using a button to enable a macro

      @samlogan87 ```

      Any trigger number # greater than 1 causes the macro file sys/trigger#.g to be executed. 
      

      This line quoted from Wiki tells two things:
      The minimum trigger number is 1
      The macros have to be stored in /sys folder.
      I guess you've put yours in the /macro folder, which would be logical for me. (but not for everyone in the RRF dev-team?)

    • RE: Capable of running 14 motors for motion?

      @sotpurk said in Capable of running 14 motors for motion?:

      It's 3 extruders running simultaneously to print the same object thrice.

      IMHO it would be easier to build 3 independent printers, but you have your reasons to build it that way....
      If that's the main reason to build this machine, I'd like to introduce my hashPrinter.
      It only needs 11 steppers and can print four parts simultaneously in mirror mode.
      The mirror mode is quite nice, since the inertias from moving four toolheads eliminate themselfes.
      The problem with z-levelling four tools is my printers biggest issue. You can't use mesh levelling.

    • RE: Bed slinger, core XY or other. What should I build?

      @philn
      We had this discussion a short while ago and the answers are probably the same.
      If you have several printers at hand, why not build the next one with features the others don't have? (toolchanger, heated chamber, special extruder for high temp filament a.s.o.)
      Setting the goals to achieve makes it easier to pick the right kinematics.
      Eg. Bed slinger = big footprint => not the best choice for heated chamber
      Delta printer => not easy to aim for tool changing

    • RE: #- (hash) printer with super simple gantry

      Just for the record, I have configured bed leveling (G32) and mesh leveling with the mini-IR probe.
      It's blazing fast, the first G30 to set Z=0 always scares me 😱
