Moved to the firmware wishlist forum where @dc42 can evaluate it.

I know that the main concern of this type of systems, are the retractions, but from what I have been able to find out, the polymers have certain characteristics, it may be the same polymer but for different types of technologies their characteristics change, for example when they melt they flow as a liquid, but rather as a hot dough, and in theory that prevents material from dripping down the nozzle, but in case these drips occur, I plan to build a pneumatic system that stops and opens the nozzle very fast for extruder displacements . Here you can find a system that closes and opens the nozzle. https://wiki.utopiamaker.com/index.php/Extrusor_de_Pellets_para_Impresión_3D

@mildw4ve said in Extruder stepper motor tuning: The model in the photo has XY dimensions of 40x40mm, horizontal distance between ribs is around 8mm and with 11mm diameter filament gear, 0.2mm layer height, 0.4mm nozzle, I don't believe there is a correlation there. My math might be wrong though. Can you post a section of the GCode file showing at least one complete layer (not one of the the first few layers) so that we can see how much extrusion is being done per side of the cube?

@dc42 I will upload a video this weekend of the material change in process, so that everyone can see where the issue lies and better understand how the mechanical side of my filament selector works. On another note, Thank you for always being so attentive to this forum! I don’t think I’ve ever posed a question that you didn’t have some input on. I really appreciate that!

@dc42 thank you. For all the years I've worked at software and used networking I missed that pronterface was upcasing the line which meant it no longer matched the ssid. I went to repetier and did it there and now the webui is up and running. Thanks for your help
