Re: Thermoset Type Plastics used in a extrusion type printer? - 11 months ago

... repeated melting plastic materials will degrade them - so maybe better working with solvents or lower temps. One of my related ideas was to laser-sinter dark plastic powders or lignin-powder (have some from Tecnaro)

Ich habe meine noch Alle mit Pronterface/Marlin mit den Arduino-Boards (oder Marlin4Due mit ArduinoDue) und als Drucker auch eher ältere Typen (Darwin- und Mendel-Varianten, Orca, Eigenbau) ... und mich auch schon länger nicht mehr mit Kunststoff-FDM-3

Re: Voron 2.4 mit RepRap - 1 year ago

... das RepRap-Projekt wurde 2006 gestartet und die "aktivste Zeit" ging von etwa 2007 bis 2011, bis sich das Thema ausreichend weit rumgesprochen hatte ... danach haben die Chinesischen Copy-Cats "übernommen" und die eigentlichen Entwickler hatten nicht mehr so die Lust, ihre in den Foren vorgestellten Open-Source-Entwicklungen nach ein paar Monaten als (schlechte) Kopien bei Alibaba oder Amazon

Re: Voron 2.4 mit RepRap - 1 year ago

Hallo Daniel, ... willkommen bei RepRap! Nachdem die "aktive" Zeit schon etwas her ist, ist es hier im Forum etwas ruhiger geworden, die Antworten könnten also etwas länger dauern.

Re: Info about complete laser module system - 1 year ago

... you can try to apply enough current at the specified voltage to one or more of the diodes, so they start lasering and check, what amount of IR power is emitted by the corresponding fiber. To start lasering, this should be something like 4 Amps at 12V (absolute max. current is 44 Amps) with cooling on or for a short time, so the diodes won't overheat. Without reattaching the fiber you have t

Re: D9 pin how to setup the filmware - 1 year ago

Re: D9 pin how to setup the filmware - 1 year ago

... you can switch pins, not already defined/used with "M42" - e.g. with a pin number 'pp' you'll write "M42 Ppp S1" for ON and "M42 Ppp S255" for OFF (check if the state S1 and S255 are working this way or the other way round).

Re: G Code Sender for Ramps 1.4 - 1 year ago

... I've used this with Marlin4Due (but would work with any other GRBL-based firmware too) - best is to configure the E-stepper as "1 step per mm" and adjust the step-multiplier inside Pronterface or another G-code-sender or as multiplier with a converter from other vector-files into G-code (I've programmed different converter/importer for HPGL or DXF or other custom-specific file-formats too).

Re: G Code Sender for Ramps 1.4 - 1 year ago

... depending on your skills maybe some 3D-printing software will do - I'm using Pronterface for some of my laser-engravers by "misusing" the extruder-steps for laser pulses and setting the power with an analogue 0-5V output for the pulse-length (0V=5µs, 5V=300µs pulse length)

Re: Considering building a Darwin with modern twists. Thoughts? - 1 year ago

... the Darwin had a stiffer frame, but more redundant parts ... the later ones were either more simply/faster to assemble or had "fancier" variations or other "more interesting" characteristics.
