Re: German RepRap Protos V3 Firmware upates - Yesterday
... with the availability of the ArduinoDue I've usesd it first with an own BoB, last wit RADDS and RAPS128 drivers for my 3D-printers, paste-dispensers, laser-engravers and even "industrial" machines like 3-5m long ultrasonic cleaning systems with up to 5 vats ... so this Arduino isn't so bad But for later, more sophisticated projects, I've used the AI boards from NVIDIA (Jetson Nano and Jetsoby VDX - General
Re: step size, bed size for RAMPS + A4988 - Yesterday
... BED_SIZE ist mostly in milimeters, als steps are too "individually". The searching direction ist too a parameter, which is set by 0/1 somewhere - check the section, where the axes are predefined (different depending on firmware and version/date) ...by VDX - RAMPS Electronics

Hi Manuel, ... was ich als "sehr gutes" Material im Sinne von superkleine Details und Stabilität gefunden hatte, war das "Clear V4" von Formlabs - ist aber für deren Laser-Belichter Form1, also 6x bis 8x längere Belichtungszeit mit einem UV-LED-Belichter ...by VDX - Allgemeines

... ja, fürs "modelling" bzw. zum Erstellen und Modifizieren von 3D-Objekten und auch für Export in diverse Formate oder zum Slicen fürs 3D-Drucken habe ich ausreichend andere Tools da. Ist auch immer die Frage, ob man sich nochmal eine andere "Lernkurve" antutby VDX - Software

Quotenishaleon Speaking of which, VIKTOR, I still have the Scara printer reserved for you! ... which one? - some images? I'm slowly assembling a (more proffessional "parallel SCARA"), but actually mainly busy with different "laser-related" stuff and additive manufacturing in micron-dimensions with all sorts of materialsby VDX - Allgemeines
Re: Witbox 2 mit Laser umrüsten - 5 days ago
... bei den Spannungs-Convertern mußt du aufpassen - ein step-down kann auch mal direkt beim Einschalten die Vorspannung "durchreichen", bis er sie reduziert - dann kann ein 5V- (oder auch 12V-) Eingang schnell mal durchbrennen. Wegen der Ansteuerung schaust du, was deine Software als Optionen hat - bei meinen 3D-Druck-->Laser-Modifikationen verwende ich typisch die Extruder-Pulse als Laser-Pby VDX - Laser-Ecke
Re: Marlin Firmware Extern Extruder input - 8 days ago
... maybe reduce the complexity by controlling the temperature and drive the extruder stepper with two differen small Arduinos? ... eventually even use a "normal" temp-controller for the temperature. Then the targeted extruder-speed could be exported as 0-255 over the I/O's and the "speed"-Arduino will simply decode the bits and drive the extruder-stepper accordingly - then it's as easy as modifby VDX - Firmware - Marlin

... wenn du genauere Tast-Sensoren haben willst, dann ggf. kleine Inis mit einem "Tast-Stift" versehen - praktisch eine kleine Metallplatte in einem Tubis vor dem Ini, welche über einen verlängerten Taststift oder Hebel bewegt wird - dann ist der Schalt-Abstand immer gleich und der Taststift kann auf jeder Oberfläche eingesetzt werden ...by VDX - Allgemeines

Re: Is there a way to stop the current move but keep position? - 22 days ago
... ist there nowadays a G-code for "safe" stopping midway, before ending the actual move? My hassles with this were some 8+ years ago - then no way to do thisby VDX - Firmware - Marlin
Re: Is there a way to stop the current move but keep position? - 22 days ago

Re: Printhead Exclusive Ramps - 22 days ago
... by rethinking -- check all the GND connections for current loops - had this too with several power-sources, where one wa not correct set, so a voltage difference of some ten(!) Volts between the different PS-GND's, what caused problems with current loops through the USB-cable shielding (it got hot after some ten seconds) ...by VDX - Firmware - Marlin
Re: Printhead Exclusive Ramps - 22 days ago
... best should be to check the crashing cause - this is most likely vor dropping the voltage for the controller below "brown-out" level ... so maybe wrong wiring or too much current draw (or not enough PS power) ...by VDX - Firmware - Marlin
Re: Printhead Exclusive Ramps - 22 days ago
... as you'll need not only temperature control, but too moving-synchronisation between the robot and the extruder-motor, maybe better something like the 3D-printing modes as used with RoboDK? AFAIK, there were several samples for using industry-robots for 3D-pronting ...by VDX - Firmware - Marlin

Re: Info about complete laser module system - 5 weeks ago
... could be for pumping or better organizing the power-drivers and couplers. If a laser is out "of duty", then the company, dismissing it, has to "disable" it, so it won't be usefull or "dangerous" anymore ... this is mostly done by cutting all the caples connections and laser cordsby VDX - Laser Cutter Working Group

Re: Info about complete laser module system - 5 weeks ago
... where are you located? A friend (he and me are located in Germany, if shipping ist an option) managed to splice an external fiber to a cut one, but it's not so easy to recalibrate the new fiber, ift it's not a "plain CW" but a QCW (Quasi CW) or pulsed laser mode - and, could be, you can't run it with full power again. The "10kW" could be a "worst case" scenario or it's a partially pulsed moby VDX - Laser Cutter Working Group
Re: Info about complete laser module system - 5 weeks ago
... it looks, there are ten 270W-diodes with complete fibers, so pretty "good stuff" If the electronic is working, then check, if the external fiber ist cut - it could be spliced again with a new fiber, but this isn't so easy. If the external fiber is OK, but the electronics is broken, then you can remove the electronics and support the diodes with up t0 40Amps current (single or in series) -by VDX - Laser Cutter Working Group
Re: Filamanet (PLA) zerbricht plötzlich über Nacht - Erklärung? - 5 weeks ago
Hi Reiner, ... du kannst ja mal mit ein paar Stücken ausprobieren, ob die sich wieder "regenerieren", wenn du sie in einer Kiste mit feuchter Luft ein paar Tage lagerst ... alternativ, sollte das Problem eher aufgenommene Feuchtigkeit sein, ggf. eine Stunde im Backofen bei 60°C oder in die Sonne legen ...by VDX - Extruder, Hotends & verschiedene Materialien
