Re: Enable 12v-pin on board (MKS robinv2.3) - 22 Tage zuvor
... hmmm ... some of my (12V) LED-stripes have already internal current regulation, so simply connecting to a 12V PS would be enough. Others (mostly RGB-types) have either 4 pins for the "colors" and GND or 2 pins for the current and one for the selection or serial data. Do you have a link to your specific type or the data sheet?von VDX - Firmware - Marlin

... some other methodes to coat printed housings with metal is to spray or paint it with a conductive material, then use galvanics to coat it with the metal, previously solved in the galvanic bath. Here are some paints or copper-stripes or other eventually usefull and slightly cheaper conductives -von VDX - Firmware - Marlin

... there are some, but not conducting as good, as pure metal ( or [3dk.berlin]) I'm coating the surface with a thin layer of metal and repeat this, until the thickness is sufficient for the needed current. But the material could be any other typt too - plastic, ceramic, glass, ... - or any combination in any count or variation of materials in the stacked "layers".

Re: Probe Wizard: Missing reference to based "paper" thickness? - 23 Tage zuvor
... in one of my actual projects I'm trying to create and to "print" ultra thin layers with down to some hundred nanometer thickness -- but it's not with "common" FDM, but more with thermo-transfer ... but too, experimented, what's the thinnest layer height, possible with FDM and smaller bore diameters - best was 20 microns with a 0.1mm (100microns) bore, but not really usefull or reproducible .von VDX - Firmware - Marlin

Re: Probe Wizard: Missing reference to based "paper" thickness? - 23 Tage zuvor
... IIRC it was first pretty simple, without any internal compensation, as you move the head in Z, until the paper is just caught, then set this position as "0". The next, more "comfortable" adjust, was the Z-offset parameter, measured with the "paper methode", then saved into the parameter set.

... with my methode its halfway between "FDM" and a "paste-dispenser", what I was developing and using many ears. Instead of a heated chamber to melt the material and extrude it in a "semifluid" state, I'm touching the surface with a "cold" wire and then only melt the tip, touching the surface, so it forms and releases a droplet of molten metal, if retracting the wire before switching the laser(von VDX - Developers
