... best bet could be a divider (or multiplicator) to get different step counts for the two extruders. This could be done with a separate Arduino or ESP32, if the factor isn't achievable with a simple counter IC.by VDX - Printing
Hello Marcos, depending on your needs there are many different sub-forums like for firmware, electronics, mechanics, PC-software and many more. One essential hint - when searching through the forums, then change the searcch date range in the bottom of the mask from "Last 30 days" to "All dates", or you won't find anything usefull ... most interesting infos are much, much olderby VDX - General

... by the way - with the galvanic approach you can easy manufacture any size and form of tips and probe-points, which you can get as "hollow form" in a plastic sheet. This would be a perfect use for the UV-LCD-3D-printers with roughly 25 microns big "voxels". With some tweaking you can get even finer resolution, if you modify a common data-beamer with an UV-LED as light source and adding a redby VDX - Tech-Talk
... I had a cooperation (more I had to help them solve some handling issues), from where I've got a bunch of "nano-nailheads" -- it's essentially a halfsphere of gold or platinum with 30µm diameter with a 30 or 50µm long "nano-needle" centered at the flat side.

... with the "laser-thermo-transfer" some nanometer thick layers can be "sprayed" or more like "PVD" coated (as in Physical Vapor Deposition) - the lower limit are actually the spot sizes of down to 50 microns with laser diodes or down to 10 microns with fiber-lasers and such (have some UV-DPSS and actually an "green" picosecond laser for testing until end of May).

... for some decent "microfabrication" in sort of a DIY approach you can use lasers with a fine spot - common fiberlasers have spot diameters around 30 microns, with different optics even down to below 10 microns.
