Re: GRBL to Reprap converter - 7 months ago
... first check the differences between your "brand" of GRBL and too, your "brand" of G-code ... it's mostly identical (same basics), but could differ in special M-codes and "newly added" G-codes for e.g. bed-levelling or such. If there are only minor differences, then you can script your own "translator" without problems ... or even do this manually in a text editor by replacing/adding the specby VDX - General
Re: Learning gCode? - 7 months ago
... if you are halfway experienced in programming, then you can modify existing or even create new g-codes or "macros" by implementing them into the parser (firmware) - it's not this hard to do ...by VDX - General

Re: Problem using Ramps 1.4 with LabView - 7 months ago
... I was using the ArduinoDue (with RADDS boards) -- AFAIK, it could be used with a RAMPS board too, if the boards is modified to 3.3V power support for the Due ... but better check, if true ...by VDX - RAMPS Electronics

Re: PCB Exposer Marlin Firmware - 7 months ago
... in the past I did PCB-layout and CNC-milling with Eagle and export to NC/Gerber or PLT/HPGL. Then switched to Target and got even more export-options or prgrammed several converters from HPGL or DXF into Gcode for Pronterface+Marlin ... last was with laser-engraving by removing the copper directly.

Re: About Two Trees DB5500s Laser Module - 8 months ago
... no, most likely 12V only - it's typical "chinese style" to give nonsensical infos ... the driver is a constant current type, regulated on the secondary side - if you rise the input voltage, it gets hotter, but shouldn't give more output ... and above a specific threshold it simply wrecks the laser diode and/or explodesby VDX - Laser Cutter Working Group
Re: About Two Trees DB5500s Laser Module - 9 months ago
... MDF is a pretty dense material, so its much harder to cut than wood. You can optimize the cutting speed/efficiency with blowing compressed air into the laser spot to remove the fumes and ash faster and too with some "tweaking", as two parallel cuts with around 0,1mm separated. By the way -- the "40Watts" is not the optical power, but something like the more than maximal allowed drawn electrby VDX - Laser Cutter Working Group

Re: Wo sind alle? - 9 months ago
Hi Terri, Dir Alles Gute zur Abschlußarbeit! Für mich war die aktive Zeit mit der RepRap-Entwicklung seit 2007 immer auch ein "Hinzulernen" und brainstorming für diverse andere Themen und Applikationen - mit den klar definierten "Unzulänglichkeiten" des (Hobby-) FDM-Drucks haben wir uns auch immer wieder mal überlegt, wie/was da noch möglich wäre -- haben da auch mit dem Resin-Druck angefangenby VDX - Allgemeines
Re: Wo sind alle? - 9 months ago

Re: Mega's AMS 1117 5V Getting Hot with RAMPS 1.6 + 128*64 LCD - 10 months ago
... could be a "semi-short" somewhere or something is oszillating wildly. Check for shorts or low resistance especially at the endstops. Best methode for checking external loads is with unplugging them and mesuring the drawn current ... caution with th estepper drivers! - they could burn when plugging/unplugging the motors when powered.by VDX - RAMPS Electronics
Re: Heatsink pastes for hotends - 10 months ago
... with proper cooling (e.g. pressing the resistor body to/into a "thermal mass") you can "overdrive" this type of normally air-cooled resistors to maybe 5x to 10x the rated value - so a "5Watt-resistor" could excert up to 50Watts of thermal energy ... maybe even moreby VDX - General
Re: DIY quick change extruder/hotend system - 10 months ago
... yes, this forum is sort of aged ... but as long as its functional and usefull, there are some people beside me, maintaining it ... if we have the time ... so hold on!

Re: Advice on UV Resin Curing for 3D Printed Cosplay Helmet - 10 months ago
... sunlight should cure UV-resins instantly - if there too is a "soft" film, then this is Oxygene-inhibition, whats common with most resins, if stored in normal ambient. With your cahmber - it coud bee, the light/energy-density isn't sufficient ... industrial grade UV-curing boxes use up to some hundred(!) watts of 405nm UV-light or less for shorter wavelenghts ...by VDX - General

Re: German RepRap Protos V3 Firmware upates - 10 months ago
... the "German RepRap" was in the beginning cooperating with RepRap-developers, but from the second year on they separated and built their "own" hardware and controllers, which weren't documented publicly. So, as the_digital_dentist suggests -- better replace it with a (modern) electronics with complete documentation ...by VDX - General
Re: German RepRap Protos V3 Firmware upates - 10 months ago
... yes, there are newer/better solutions with time ... but seems, there are enough of the "older" systems running smooth nd reliable still -- so depending on the individual circumstancesby VDX - General
