    • RE: HELP! New Cast Alum. Bed doesn't seem to AutoMeshLevel

      One thing not mentioned by anyone is the G31 probe offset. Are you sure it's OK?

    • IDEX printer plays TicTacToe (soon)

      To celebrate the new level of 3D printing named conditionals and variables I thought it would be funny to rebuild my old Prusa i3 to an IDEX with infinite Y-axis.
      A macro would then apply Tic Tac Toe rules to the two feltpen-tools which actually write X and O to a foil on the bed.
      The infinite Y-axis would then scroll the foil around and thereby wipe off the nonpermanent ink.

      With this thread I want to encourage other users to think out off the box and come up with their crazy ideas to celebrate the amazing Duet team and their breakthrough Firmware.

    • RE: Mini IR Z probe Nightmare

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

      @Phaedrux
      Now that I have a working homeAll procedure, I've edited the existing gcode-files and the slicer start/end procedures. The wrong layercount is history now.

      There's a typo in the drive-mapping. Maybe not....? Sorry

    • RE: G30 S-1 is giving me heart stitches [SOLVED]

      This is the latest report:
      I've updated to rrf3.2, changed a few minor settings from the config file I got from @Phaedrux (Z motor and probe needed to be inverted)
      But still...
      g30_insufficient.jpg

      I also changed the z-probe port from zprobe.in to e1stop, but no change.

      Anyone any idea? @fcwilt I'm now on rrf 3.2, you can chime in anytime 🙂

      Is it possible I have my XY stepper config wrong? Their connectors would fit the Molex headers in both ways. They move the right way, but you never know...this is my last straw.

    • RE: Wait for passive thermistor temprature to stabilize

      @garethky
      I have a bit of programming experience, but I'm relatively new to the RRF conditionals.
      To me it seems, your routine breaks when the momentary value is close enough to the target value?

      That doesn't tell you the temp has stabilized, it's just a coincidental match.
      The real temp graph could be in a wild overshooting phase and you won't notice.

      What really tells you the temp has stabilized, is the difference between momentary max. temp and min. temp.
      If this difference is smaller than your threshold you're ready to go.

      I can't comment on the BLtouch, but talking about losses Add a USV to your printer or a big battery to avoid power-issues.

    • DBOT gantry now 600gr lighter

      Hi guys,
      when I built my DBOT 3 years ago, I wanted to add mgn12 rails. But my CAD skills were pretty low, so the first attempt was very bulky and heavy.
      Now I've re-designed it and it is around 600grams lighter than before. The angled steel bracket to mount the Titan and the 2020 crossbeam had the biggest impact on the scale. (literally 😉 )

      The hotend bracket still has some details I want to change, but I'll post the final design on thingiverse after some real tests.
      A short drytest with 180mm/s printspeed was succesful, without the need to tie down the printer.

    • RE: PID tunning - heated chamber

      @Chris25 and @Phaedrux
      Wouldn't it make sense to heat up the printbed, before and while you are doing PID tuning of the heated chamber? IMHO, that's the real world scenario.

      The 2kW heater, does it have a huge thermal capacity (like an oil-radiator) or does it heat the air up immediately? Is there a chamber fan?
      Maybe you have to warm up the heaterbody before you start tuning. It sure is an AC heater.

    • RE: Wrong values shown for M92 (and other?) in DWC3.3.b2

      @droftarts
      If I'd follow that logic, I'd allow 0.001 steps/mm to avoid 'division by zero' problems.
      But in my case it wouldn't drift towards eternity, but to zero time.
      OTOH an acceleration of 0 would take forever

    • Wrong values shown for M92 (and other?) in DWC3.3.b2

      For a test print I change the extruder M92 values to zero. I checked it in the console and they showed E1.000:1.000 instead.
      The extruders didn't move, so it's just a cosmetic bug in DWC?

    • RE: Virtual (shadow) drives

      @nuramori
      @dc42 said, I could change the whole kinematic model 'on the fly', so it's worth a try..
      Some parameters can't be changed mid-print, it would be nice to have a table about those do's and don'ts

    • 5-axis styrofoam hotwire cutter?

      Hi guys,
      there are some interesting threads about 5-axis 3D printers, but I haven't seen anything for hotwire cutters?

      In the past I used to cut RC-model wings and fuselages (from styrofoam or EPP) with a manual guided hotwire. There were some CNC machines too but they could only cut straights. Too expensive for what they could do.

      What if we had a 5-axis hotwire cutter with adjustable wire length (*), that works on a rotating 'Steward' platform? (or other fancy Table-dance mechanic)
      We could cut 'low-poly' parts of almost any shape in no time. Much faster than a CNC mill or 5-axis printer, I guess?
      Those low-poly parts can then be refined further with a mill (sitting on the same machine?) if necessary.
      *) the wire length would stay the same, but the tool head would use adjustable rollers to reduce the active length.

      I'll put that on my wishlist amongst all the other projects, I'll never finish 😉

    • RE: 3D printer Super-GAU

      @alex-cr
      The ballscrews are already back in place, but I took the chance to rethink my bed mounting and ordered a longer GT2 belt. I want to place the ballscrews outside the printhead-area.

      It has to get worse, before it gets better, they say...

    • RE: Unexpected inner wiring in stepper motor

      @sidsm
      Maybe that's the reason, why they were in the 'clearance' section? It's not unusual for big steppers to have upto 8 wires, (2 coils with separate center wires). Maybe they mixed them up the wrong way?
      Ask OMC for clarification, if they are able to replace them...if not, open them and inspect the wiring. We can help finding a solution.

    • 3D printer Super-GAU

      IDK how I managed to screw up my printer-coords, but I've 'succesfully' disassembled my ballscrews. 😢
