Eerste is, ik werk voor een bedrijf zonder CAO al wordt dat hopelijk nog wel ooit iets. Verder ben ik ook geinteresseerd in de rechtsbijstandsverzekering die onderdeel is van sommige vakbonden. Die van CNV kun je bijvoorbeeld ook voor niet-werkgerelateerde zaken inzetten wat wel interessant klinkt. Wat zijn jullie ervaringen?
Does any of you have any experience with this? I'm looking at the Felfil Evo pellet extruder which seems like an acceptable option. One thing I don't understand. Why are the shredder and spooler so ungodly expensive?
I mean, can't you just use an old blender to grind pieces down far enough for the pellet extruder? The finer the better no? Airborne microplastic may be a concern at some point.
Also the spooler. Is that more complicated than a stepper motor that runs at a certain RPM spinning the spool around? With perhaps a mechanism that slows down a bit after X rotations to compensate for the spool getting thicker. Nothing an Arduino can't handle. Also don't grip the spool that tightly so pull strength is more or less equal.
Both the spooler and shredder individually cost more than a pellet extruder does..
In a transformer, why are both coils apart from each other? Wouldn't make more sense to have the ferrite core (tube shape), wind the primary coil around that and then wind the secondary coil on top of the primary? So that the magnetic fields are as close to each other as possible?
Hi all
A higher nozzle diameter has the benefit of being able to print faster due to to bigger layer width. There is a tradeoff, you'll have to lower print speed and/or raise temperature to maintain proper layer adhesion. That means that there is an optimal nozzle size for a given print speed/temperature combination. You also don't want temperature too high because it will burn/degrade your filament.
In my experience layer adhesion is quite poor with a nozzle of 0.8mm and it also prevents you from printing finer details (gear teeth for example). The tradeoff versus a 0.4mm nozzle doesn't seem worth it especially if you print overnight.
What are your experiences?
I'm interested in learning how to make a proper PCB rather than perf board with wires all over the place.
