Re: The beam of this laser is very bright, and the luminous effect is very good - 18 Tage zuvor
... can you please stop spamming all laser-forums, I'm reading, with your laser-beam pictures? If this went further, then I'll have to step intovon VDX - Laser-Ecke
Re: New Wiki page: Bed Leveling Probes - 20 Tage zuvor
... maybe some sort of "air-pressure-probes" could be interesting too? It's essentially a tube emitting a weak air-stream and a pressure sensor inside the tube, where the pressure will rise, when the tip is near a surface, which is hindering/blocking the stream.von VDX - General

Re: Feasibility of Using Diesel Injection Pumps for DIY Water Jet Cutter: Seeking Expertise - 26 Tage zuvor
... a friend of mine was designing and building (commercial) water jet cutters -- his pumps delivered from 4000 to 6000 bars and used clean water or added abrasive dust - then with nozzles out of sapphire or diamond. With so much lower pressure it should be much easier to get it DIY ... but maybe too, yo can look into sapphire or ruby nozzles, as used for FDM-3D-printing. For another project Ivon VDX - General
Re: Anyone successfully get PWM laser support for STM32 going? - 5 Wochen zuvor
... if it's a firmware for 3D-printing, then you have another option, what's maybe even better -- for controlling lasers with Pronterface and Marlin4Due I'm using the extruder step signal to generate "speed independant" laser pulses - with this I'll get constant and pretty precise "pulses per mm", so regardless, how slow/fast its moving, the averaged power per mm is the same For another solutiovon VDX - Firmware - Marlin

Re: Schrittmotor mit Ramps 1.4 und Schrittmotortreiber DRV8825 - 6 Wochen zuvor
... die maximale Schrittfrequenz hängt von der Mikroschritt-Auflösung bzw. der Jumper-Einstellung ab - je "feinere" Mikroschritte, umso schneller kann der Stepper angesteuert werden. Wenn du die Spulen-Paare einzeln "herumdrehst", dann ändert sich auch die Drehrichtung des Motors ... am "Vibrieren" wird sich dabei nichts ändern. Hast du ein Oszilloskop oder einen Bekannten der eins hat? - damitvon VDX - Software

... zum Strom - wenn die Parameter sonst passen, kann der Strom auch weniger sein - ich lasse z.B. NEMA-23-Stepper, die für 2.5A spezifiziert sind, auch mit "nur" 1.5A laufen ... die schaffen immer noch bis 400mm/s bei einem meiner Pastedispenser mit "schwerer" CNC-Mechanik und Zahnriemen. Wegen der Schrittfrequenz - schau mal, was du bei der Voreinstellung reduzieren kannst ... sonst setze dievon VDX - Software
Re: Schrittmotor mit Ramps 1.4 und Schrittmotortreiber DRV8825 - 6 Wochen zuvor

Re: Delta with more than 6 arms - 7 Wochen zuvor

Re: IGUS rod end vs IGUS ball and cup joint - 7 Wochen zuvor
... the "double ball joints" were my solution for a "stick'n'slip" problem when using it for etreme fine positionig -- if you look into my images, every joint consists of 2 ball magnets, rolling on each other, so no gliding and no stick'n'slip (was meant for micro-positioning with a working range of below 50mm square and step resolutions near to single microns). But then too, the "joint" is notvon VDX - Delta Machines
Re: IGUS rod end vs IGUS ball and cup joint - 7 Wochen zuvor
... with the double-ball joints you''ll have a "nonsingular" joint, so the kinematics are more complex ... but with only one magnetic ball, an iron-counterpart and a PTFE-ring to give some microns distance, it's the same, as with the ball'n'cup jointsvon VDX - Delta Machines
