Re: Endstops -x Homing - 11 Monate zuvor
... hab' momentan nicht viel Zeit - schau mal, ob du bei "Marlin\src\gcode\calibrate\G28.cpp" die passenden Sequenzen findest oder zumindest die jeweiligen Makro-Aufrufe. Das ist jetzt in "Marlin-bugfix-2.1.x" ... sollte in 1.1.x aber evtl. auch ähnlich zu finden sein ...von VDX - Software
Re: Endstops -x Homing - 11 Monate zuvor
... hmmm ... ich versteh ehrlich gesagt dein Problem nicht. Der Homing-Zyklus läuft ja selbständig ab und stoppt auch entsprechend, wenn der passend zugeordnete Endschalter getriggert wird ... dann fährt er raus, bis Trigger wieder weg und dann nochmal laaangsam in den Schalter, um die Trigger-Position exakter zu treffen. Das Einzige, was du dafür machen mußt, ist die Achs-Richtung und den MIN-von VDX - Software

Re: A route for distributed electronics manufacturing ? - 11 Monate zuvor
... I've got some "internal" numbers from Texas for life-span of their DMD's when exposed to UV radiation without UV-filter ... was then interested in using beamers for 3D-printing with UV-sensitive resins and 405nm LED's or 355nm lasers. They stated some ten hours max., more like 2-4 hoursvon VDX - Tech-Talk
Re: A route for distributed electronics manufacturing ? - 11 Monate zuvor
... DMD's are not long lasting enough for high power lasers or UV exposure - UV makes the plastic hinges of the micro-mirrors brittle, too high power will melt/wreck them with time ... best suited are galvosvon VDX - Tech-Talk
Re: A route for distributed electronics manufacturing ? - 11 Monate zuvor
... for better controllability of the thickness you can coat the "donator" plate with a thin layer of some micrometer thickness, an then control the transferred or recondensing surface thickness by the laser power - got some 10 to 100 nanometer target thickness out of 3 to 5 micronmeter thick donator sheetvon VDX - Tech-Talk
Re: A route for distributed electronics manufacturing ? - 11 Monate zuvor
... good work and thumbs up! What could be interesting for you too is the LIFT concept (Laser Induced Forward Transfer), which is pretty old/well known (since 30 years with lasers, since 50 years with focussed high energy light) and actually too used for micro-chip and sensors manufacturing. Here one example site, to get a fast grip - It's using the same basis principle, but is more centeredvon VDX - Tech-Talk
Re: Pronterface Missing -Z Jog Option? - 11 Monate zuvor
... try the same with hovering the mouse above the XY-"target" -- it's the same for the Z-"buttons" too - they arent't "empty", but only lack the numbers for not overloading the graphics ... this was designed so and hadn't caused any issues over the years ...von VDX - Printrun/Pronterface
Re: Pronterface Missing -Z Jog Option? - 11 Monate zuvor
... there was no negative indication on the Z-jog or XY ... it will move into only one axis direction, if it's not homed correctly or outside of the "allowed" moving range. Here a screenshot of my old modified Pronterface from arond 10 years ago:von VDX - Printrun/Pronterface
Re: Pronterface Missing -Z Jog Option? - 11 Monate zuvor
... IIRC, you can set an offset in the firmware and you can define the "home" coordinates in pronterface too ... didn't work with it some years now ...von VDX - Printrun/Pronterface
Re: Pronterface Missing -Z Jog Option? - 11 Monate zuvor
... you have to configure the axes directions and switch-positions (min/max and eventually inverting the switches) accordingly to your setup, otherwise it can show such behaviour.von VDX - Printrun/Pronterface
Re: Pronterface Missing -Z Jog Option? - 11 Monate zuvor
... check for the ref-button-status with "M119" - if not "homed" for Z or still triggered status, then it runs only in one direction ...von VDX - Printrun/Pronterface

In "meinen" Faserlasern habe ich jeweils den Controller E1701D von HAlaser drin, welcher auch die IPG-Faserlaser direkt ansteuern kann ... zur Not könnte ich den IPG auch probeweise an einen meiner Convon VDX - Laser-Ecke

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 ...
