Hier wollen wir Projekttagebücher sehen. Egal ob der Bau eines neuen Druckers, die Konstruktion eines Hotends oder ein neues Softwareprojekt, gerne verfolgen wir die Entwicklung und kommentieren sie. Bitte nur konkrete Projekte, keine fernen Vorhaben!
Re: Laserdioden werden immer stärker - wofür verwenden? - Heute
... da mich immer wieder mal jemand fragt, wie das blaue Laserdiodenmodul mit den 8x4.5W-Laserdioden tut - hier mal ein Demo-Video, bei dem ich die 8 Dioden einzeln zu- und wegschalte - pro Diode habe ich knapp 3A und etwa 4.3Watt @450nm, Alle zusammen geben dann etwa 35Watt auf einen Spot von ca. 0.3mm Durchmesser aus (das vergrößerte 8x-Spot-Fernbild an der Wand praktisch auf 0.3mm reduziert):von VDX - Laser-Ecke
Re: Endstop issue - Heute
... could be, the I/O-pin is not correct assigned or defined (pull-up or -down). For working without homing you have to invert the signal polarity (so it's not triggered anymore) and avoid homing/referencing ...von VDX - Printing
Re: Peltier module connected as platform for 3D printing, need your help

... when testing with 3D-printing on my CNC-mill I've used an external "industrial" temperature controller for the heated bed ... this would work with peltier cooling too ...von VDX - Developers
Re: Marlin 2.0 Temperature reading issues - 5 Tage zuvor
... this maybe shows another problem - could be, you're shorting the voltage level with the triggered endstop below a sound level. So better recheck the pins and orientation of your endstop connections ...von VDX - Firmware - Marlin
Re: Marlin 2.0 Temperature reading issues - 7 Tage zuvor
... check the connection of the endstop signal, +5V and GND to the temp-reading I/O-pin and +5V and GND of the Atmega - there is either a connection missing or wired wrong ...von VDX - Firmware - Marlin
Re: 128x64 lcd does not work with mks tinybee! - 9 Tage zuvor
... so it was hardware! - there are some "rules" to connect and mark the cables, to make it easier to check for eventual failures ... for this are the "red" wires at the cables sides. If it's not proper documented and/or installed wrong, then its still a hardware failurevon VDX - Firmware - Marlin
Re: 3D Zeichenprogramm - 10 Tage zuvor
... für "komplexeres" habe ich noch eine alte Version von Lightwave - das wird aber kaum einer hier kennen -- kommt ursprünglich aus der Mac-Welt und wurde für 3D-Animationen in Werbeclips eingesetzt ... ich hatte damit Anfang der 2000-er für die damalige Firma "mikro/nano-Konstruktionen" damit designt und manchmal auch eine animierte "Welt" für eine Messe-Vorführung o.Ä. ...von VDX - Software

Re: 128x64 lcd does not work with mks tinybee! - 10 Tage zuvor

Re: Kreise werden mit Unterbrechung gefahren - 11 Tage zuvor
... etwas ähnliches hatte ich bei einigen Vektorprogrammen bei Exportieren nach HPGL - da wurde das jeweils letzte Segment eines Kreises entweder gar nicht mit exportiert, oder in der "falschen" Richtung verbunden - praktisch wie bei dir, die Verbindungslinie war zwar drin, aber praktisch "falschrum"von VDX - Software
Re: Maybe the World's Lightest Extruder - 11 Tage zuvor
... what's the stall-force of your piezo motor? The radial weren't so strong - have some linear (pushing an Al2O3-rod) with 8N stall force, but less for "sound" operation -- have them in reserve, when in need for an AFMvon VDX - Tech-Talk
Re: Maybe the World's Lightest Extruder - 12 Tage zuvor
... so thumbs up from me! If you're seraching powerfull micro-motors -- there are two main companies, building some - Faulhaber and Maxxon ... was developing assembling tools, stages and ideas for the smallest motors of them around 15 to 20 years agovon VDX - Tech-Talk
Re: Maybe the World's Lightest Extruder - 12 Tage zuvor
... hmmm ... if you have the possibility to get hands on a marking laser - was experimenting with laser-engraving screw heads to get more "grip" or friction on the surface ... meant for filament transfer - but could be helpful here too ... here the related post: And here the video, engraving one of the srew-heads (was something different for "give-aways") - This could be done with the surfavon VDX - Tech-Talk

Re: Anybody got a DIY filament maker / extruder? - 19 Tage zuvor
... AFAIK they got pretty "perfect" windows ... the "isotopic uniform" synthesis too got super-flat sheets ... which could be grown even thicker. Could be, there was some misbehaving for the "synthetic" vs. "natural" diamond folksvon VDX - General
Re: Anybody got a DIY filament maker / extruder? - 19 Tage zuvor
... exactly my thoughts then too! ... but after showing excellent results this didn't got into use ... some other, "promising" developments too, didn't survive/maturevon VDX - General
Re: Anybody got a DIY filament maker / extruder? - 19 Tage zuvor
... it's not only a hypothesis -- some 20+years ago there were developments for better chip-cooling, where the chips would be placed not on ceramic substrate, but on thin diamond-layers with superior isolation and thermal conductivity, which were made/synthetized with this methode. They even managed to create "isotopic pure" diamond windows with much better thermal conductivity than made fromvon VDX - General
Re: Anybody got a DIY filament maker / extruder? - 19 Tage zuvor
... think about a setup with carbon, oxygene an hydrogene ions in a closed tank at 900 degC, and inserting a "cooled" metal surface at around 700 degC -- there will start a "condensation" or better "synthesis" of different types of carbon molecules from graphene, graphite, fulerenes, carbon nanotubes to diamond ... the less stable molecules will be "resolved" again by the hydrogen ions, so only tvon VDX - General
Re: Anybody got a DIY filament maker / extruder? - 19 Tage zuvor
... my best bet for graphene is focussing on "big" monomolecular layers or "endless" stripes and strands -- this is the most valuable direction for graphene or similar materials (e.G. "borophene"). I have an idea for the synthesis of "endles strands" with a merely simple setup ... but actually no partner or possibilities to do this in a "serious" way ... more than occupied by my day-job, which ivon VDX - General

Re: Extending cable for paneldue - 21 Tage zuvor
... you can "elongate" even unshielded cable by soldering some resistors with ranges from 100 to around 470 Ohms (depends on circumstances) into the data lines -- they some sort of "damping" the noisevon VDX - Duet
