... 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
... 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.

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
... das kommt wieder -- meine beiden sind jetzt 23 und 25 - da hats dann wieder manchmal etwas mehr Zeit Wenn ihr mit dem spin-off loslegt, haltet mich dann auf dem Laufenden - bin auch mit ein paar Projekten zum Multimaterial-Mikro/Nano-3D-Druck dran, wo es ggf. Synergieeffekte gebn könnte ...by VDX - Allgemeines
... 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
... 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

... 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.

... 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.
