Just a little idea to improve the concept : the electrolisis is a reaction that is limited in speed by equilibrium (because of thermodynamics) as such, the faster you get rid of the aluminium ions next to the work piece, the quicker you will be able to machine your parts. There are two ways to improve the exiting of aluminium ions : - increse voltage : it will increase the electric field , E and the ions, subjects to Lorenz attractive force, F=q*E, will go away quicker. - make a directed stream of water from the cathode : thanks to the HO- ions, the metallic ions will get consumed and increase the speed of the reaction, it's called equilibrium displacement. The downside of your design is that the current of water only comes from one side of the tip making an asymmetrical reaction on the part

@7:49 recommend adding on a termination fitting with a bushing on the end of your FMC to avoid damaging your wire insulation over time. Vibration and movement will cut through over time, you may pay attention to prevent that but many others won't. Important to think about when releasing a new product. Open source?

You need a air line around the nozzle so the water is dispersed as you're machining it. It will improve the accuracy a lot.

How much needle will wear and looses its shape? You told would insulate needle, maybe like using emalic coating? (like coil copper wires) Is Aluminium faster than Steel? Do it make it more accurate? How small holes/slots could made? I would need max 1.0mm grooves to 6-10mm thick piece, not suiting for ECM?

@nosuchthingasshould41754 жыл бұрын
If you drilled first all the way through the work piece and only then started moving horizontally, wouldn't the cutting go faster? You'd be using the entire surface of the needle? Also, I looked it up and in industrial applications they tend to use conductive molds, negatives of the work piece. So how about print the mold in plastic, cover in conductive paint, install on the carriage and lower over the work piece.

Correct me if I'm wrong but it seems like the spring loaded auto leveling thing is unnecessary. Because both the needle and the part are conductive, you could just test connectivity between the needle and the bed as you lower it. Is there some advantage to the spring design that I'm missing?
@3er24t4g13 жыл бұрын
From the looks of it, the bed level sensor and the needle are on different circuits so they need different connections

A finished stepper motor costs less than the price of the metal you would need for the housing if you made it yourself. As long as parts are available there is no point in making them yourself. This only becomes useful when you need custom parts. Even then metal prices are insane for small quantities with the prices being 5-10x what a manufacturer pays. In many cases it is cheaper for me to buy a microwave than it would be to buy the steel sheet used for the housing.

Great project! I'm tempted to try something similar on my own 3D printer, so I'm curious what sort of filtration you use with your salt water solution. I'm hoping to go the route of jet ECM but I'm not sure if a 34 gauge needle could withstand non-trivial amounts of aluminum hydroxide. Would it be simpler just to use a new batch of salt water every cut?
@MorlockEngineering3 жыл бұрын
I dont use any filtration and on smaller diameter needles it leads to clogs. I recommend just using new salt water and throwing away the old stuff

Very interestingn project but the way you machined the plate was done poorly. Why only limit it at 300mA? You removed your hotend which usually draws about 3A and your heated bed draws about 10A both at full power. So then why are you pumping out 1/40 of your psu capability?
@MorlockEngineering4 жыл бұрын
I am glad to have some criticism. Your concern is valid. When conducting these tests I used a multimeter to measure the current during operation that was being drawn by the electrode (300 mA). This was very low. Especially considering that nothing else (hotend or the bed) was on. I think this is because of the power supply I am using, which does not force enough current through the electrode.

@@Bisofication Yes, I have tried changing the distance. I found that minimizing it produced cleaner results. The best results thus far were achieved using an initial distance of 0.2 mm, with a movement 0.025 mm down every 2 passes The needle was powered by a PC computer 12 volt power supply. One ground line was attached to the needle through a relay. A 12 volt line went to the workpiece
