... ist there nowadays a G-code for "safe" stopping midway, before ending the actual move? My hassles with this were some 8+ years ago - then no way to do thisvon VDX - Firmware - Marlin
... AFAIK all "safe" stops with known position will first end the actual move ... this could be even a pretty long one (had this with a 4m wide XZ-machine) ...von VDX - Firmware - Marlin
... by rethinking -- check all the GND connections for current loops - had this too with several power-sources, where one wa not correct set, so a voltage difference of some ten(!) Volts between the different PS-GND's, what caused problems with current loops through the USB-cable shielding (it got hot after some ten seconds) ...von VDX - Firmware - Marlin
... best should be to check the crashing cause - this is most likely vor dropping the voltage for the controller below "brown-out" level ... so maybe wrong wiring or too much current draw (or not enough PS power) ...von VDX - Firmware - Marlin
... as you'll need not only temperature control, but too moving-synchronisation between the robot and the extruder-motor, maybe better something like the 3D-printing modes as used with RoboDK? AFAIK, there were several samples for using industry-robots for 3D-pronting ...von VDX - Firmware - Marlin

... IIRC, when starting with my paste-jetters, I've set the min-temp to 5 degC and "faked" the thermistor with a 100 Ohm resistor ... after this, the next step was to reflash the firmware ...von VDX - Firmware - Marlin

... could be for pumping or better organizing the power-drivers and couplers. If a laser is out "of duty", then the company, dismissing it, has to "disable" it, so it won't be usefull or "dangerous" anymore ... this is mostly done by cutting all the caples connections and laser cordsvon VDX - Laser Cutter Working Group

... where are you located? A friend (he and me are located in Germany, if shipping ist an option) managed to splice an external fiber to a cut one, but it's not so easy to recalibrate the new fiber, ift it's not a "plain CW" but a QCW (Quasi CW) or pulsed laser mode - and, could be, you can't run it with full power again. The "10kW" could be a "worst case" scenario or it's a partially pulsed movon VDX - Laser Cutter Working Group
... it looks, there are ten 270W-diodes with complete fibers, so pretty "good stuff" If the electronic is working, then check, if the external fiber ist cut - it could be spliced again with a new fiber, but this isn't so easy. If the external fiber is OK, but the electronics is broken, then you can remove the electronics and support the diodes with up t0 40Amps current (single or in series) -von VDX - Laser Cutter Working Group
Hi Reiner, ... du kannst ja mal mit ein paar Stücken ausprobieren, ob die sich wieder "regenerieren", wenn du sie in einer Kiste mit feuchter Luft ein paar Tage lagerst ... alternativ, sollte das Problem eher aufgenommene Feuchtigkeit sein, ggf. eine Stunde im Backofen bei 60°C oder in die Sonne legen ...von VDX - Extruder, Hotends & verschiedene Materialien
... das kann neben Wasser auch der "Austausch" (abgeben oder aufnehmen) von Lösemitteln o.Ä. sein - hab' in den Kellern auch einige "Veränderungen" an Materielien, die entweder aushärten bis "spröde" werden, oder auch z.B. "weicher" bis "verflüssigen"von VDX - Extruder, Hotends & verschiedene Materialien
... yes, I've did this some years ago for a company development (for pastedispensing and lasercutting) -- was not too easy, but doable ... it's a huge amount of coding in different classes to deactivate the 3D-printing functions and adding new ones Here a screenshot and some of the new "toolbox"-images: You can serach here in the RepRap-forum for "giecaps" -von VDX - Printrun/Pronterface
... even better and more usable than a fiberlaser (bur more expensive too) is an UV-DPSS-Laser. For a R&D-project I've ordered a 10Watt laser (had a 20W-type for a half a year for testing) and all the needed components - here an image of the temporary setup: It's meant mainly for microfabrication with graphite and some other "R&D"-stuff ... but is pretty good with wood toovon VDX - Laser Cutter Working Group

... you can remove the fiber and drill a 15mm-bore instead - then open the housing and remove the internal focussing lens, so the collimated beam (around 4x4mm square) can escape ... then simply attach an extrnal focussing lens and you can get an even smaller focus diameter, than with a fibervon VDX - Laser Cutter Working Group
