Re: Monster8 - Marlin 2.1.2.1 Configuration for XYZE0E1AUV + Laser cooling - 2 months ago

... my "high power"-lasers and tinkering with the broken fiber-lasers and salvaged laserdiodes is all hobby - in my job I'm developing different applications for "laser assisted material transfer" with UV-DPSS- and "ultra-short-puls"-lasers ... they have 20W averaged. Some years ago, when developing jetting paste-dispensers, I've used Marlin4Due together with Pronterface/Printrun to control the

Re: Monster8 - Marlin 2.1.2.1 Configuration for XYZE0E1AUV + Laser cooling - 2 months ago

... I'm from Germany The housing in the images is from a 50 Watt CW fiberlaser - have several with different wreckage types ... some with exploded fiber-couplings for backreflection ... some with broken electronics (one with 130Watts is emitting fine, when supporting the diodes with current only) ... some with cut external fiber ... They are all air-cooled - the housing is a "sandwich" of two

Re: Monster8 - Marlin 2.1.2.1 Configuration for XYZE0E1AUV + Laser cooling - 2 months ago

... for the "medium size" diodes I'm too using peltiers - here I've reworked a fiber-laser housing with 4 ventilators into a peltier-heat-exchanger with 6x 30Watt PZT-modules. Here some images of the setup with 2 of the diodes and 3x Peltiers under every diode and a 10mm alu sheet for heat-distributing ... for an ambien temp. of around 20degC the emitted hot air will be at around 55 to 60degC at

Re: Monster8 - Marlin 2.1.2.1 Configuration for XYZE0E1AUV + Laser cooling on the chamber pin - 2 months ago

... depending on the needed cooling power (I have some laserdiodes or lasers with up to 1kW needed for proper cooling) you can think about stand-alone coolers, as common used for water-cooled lasers (one of my water-coolers has 1.5kW)

Re: Voron 2.4 mit RepRap - 3 months 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: Info about complete laser module system - 4 months 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
