Benchtop WEDM Overview 

I feel this needs an entire series explaining every aspect in detail.

I can see this soon becoming popular and widespread like 3D printers because of your videos… Great work man, excited to see where it goes from here

great work on getting all this operational. and very clear presentation. Also, cutting 1/4" aluminum at that rate on a home desktop minimill frame is a great demontration of what desktop EDM makes possible! you can make real high reliability, fully functional metal parts out of bulk materials in reasonable times! Super exciting!

Many machinists would be glad for a machine that size for cutting keyways, gear cutters, that sort of thing.

Amazing work mate, well done

Awesome! There are so many great ideas packed into this machine! Cannot wait to see where things go from here.

You make this look achievable at home! Truly excellent work

Awesome stuff! Just got my Powercore today. Planning to do a similar setup as I get more familiar with the process. Looking forward to the updates!

So impressive. 10 mm/min, this thing rips!! Well done!

This is an awesome proof of concept for the next tool that makers can use in their homes and garages. Wire EDM at home, crazy and amazing! I look forward to when these sit side-by-side with 3D printers.

This is an excellent build. I’m very impressed well done! My solid sink EDM machines don’t require a pc or any code but I can see how it is the future for a home build EDM so it’s something I’m going to learn in my old age.

connector molds and gears for everyone 🤩 that speed is fast i thought edm was slow, nice work very nice

I've been following this for a while, you really got me wanting to make one :D

Excellent work!

Wow! Amazing! I would love to build my own!

Fantastic!

Can’t wait for this. I have the stock rack robo. I’m going to purchase a second powercore for this as well! Hopefully you can put out a pdf for us so we can build it!

Geat work! Please make a regular video series about the this edm machine Another revolution in the open source world

very cool, I built a powersource some time ago but never got around to building the cutting part. Your setup looks much more compact than some of the others I've seen. I might pick this up again.

Thanks for sharing! That’s what I want next to build Just a little bit compact😁

Exelente trabajo!

This is amazing

please record more videos how this machine cuts, results and all other informations, great video - would be great to see more

bro your very good. nice change of pinions moving with that rubber band :) please consider making a ram edm one also

Very cool

This look very interesting

that is just superb, thanks so much for sharing the grbl and powercore mods, one question what size wire are your running?

Bravo..........hats off.........u make it look simple..........now a anolog system.....cheers

Interesting concept and nice controls. I'm interested in the modification you did to the grbl code, do you have that available anywhere?

Amazing! It cuts 1/4” aluminum 😮 I can tell u are also a ShieldTV owner likes me 😜

Hi! Great project. I really like how you got great results with a device that was obviously hastily assembled. I'm also an EDM fan, and currently I'm developing my own spark generator based on a better topology than the one you use. Basically, in my topology there is no huge current limiting resistor that produces a lot of heat, and there is an inductor instead, in which the desired current level is maintained (meaning you can also control the pulse current level). This inductor is both an energy source for sparks and a high voltage generator for breaking through the working medium. Also, due to the absence of a current limiting resistor, the efficiency of this topology is much higher. The designing phase is actually almost done, I'm going to start making the first prototype soon. *Looks like you have decent skills in electronics, so if you're interested in my spark generator project or willing to participate, let me know.* Also, in case of success I'm going to open source it

Cool

That’s awesome work! Using a 3018 cnc as your base, with a large water tank, what’s the effective cut area?

This is epic. Are you going to release the software at some point?

Are you planning on a BOM and/or schematics? I'd love to attempt to try and make one. Awesome work!

I have been waiting for the restock of the rack robotics power core but it didn’t happen at the advertised date. Was yours a kickstarter purchase? Do you know what’s going on with them?

Interesting wire tension setup. I'm trying something where I have motor on the feed spool and on the waste spool and a pulley between the two. The pulley is constrained to a rail and always has a constant amount of force. Either by using a constant force spring with a rack an pinion, or just by attaching a weight to it. Then a potentiameter measures the position of the pulley along the rail. If the pully rises I decrease the speed of the waste spool to provide slack. If the pulley lowers I increase the speed to take up slack. This lets me get constant feed and constant tension and lets me detect if the wire snaps because the pulley will bottom out on the potentiometer.

I would love to use thos to cut out knife profiles for my side hustle. Will there be any parts available or schematics on how to build it?

Looks great! Kickstarter when?

Any docs (BOM, etc) that we could follow ourselves? Are you thinking of open sourcing the C rewrite of the Pico code?

I feel like you could have gotten around the wire tension by using a single pulling motor and a mass on a flexible tube that will sag or rise as the tension changes. Alternatively put a constant drag mechanism on the spool with a rotary damper. If you have a high enough torque motor, a constant speed roller system should pull quite well.

nice machine never thought they were available in desktop size. is the wire reusable

Hi i bulding also a machine but at this moment i am still working on the mechanical design. I try to planning multiple possibilitys. Later in the process i can show some pictures ore drawings. About the pcb you adapt some modifications, are you going to change the pcb design ? Thank for the info

Where did you buy the wire spool?

are you purposely being vague with your acronyms? is that mega 2650 your cnc controller or do you have that separate. Awesome machine. Thank you for sharing.

damn bro that's really cool. would you consider making and selling these?

Have the Power Core guys seen this? They may want to include these changes to the upcoming V2 design.

I see you are out of stock. Could I use a EDM drill to do this? Would I need a pulse EMD Drill unit for wire cutting?

EPIC work! Wondering if any custom PCBs or CNC parts may help for any upcoming projects? Would be fun to do something together! (PCBWay zoey)

Is there a reason that you did choose to go with legacy grbl instead of grblHAL?

Hello, can you tell me what kind of rollers you used that are in the water?

What is the name of the addon used to make the python ui please ?

THis is a nice setup here. You relly need a good short video about RESULTS - show us what you achieved . Detailes-wise. it all wraps to the product - so show us those parts your machine is pumping out... Regards from far Ukraine

I’d call those ‘pinch rollers’ resemble the same part as a magnetic tape mechanism

are you plannig to make this commercial?

Why did you remove most of the capapcitors?

hmmm maybe I wont build another 3d printer after I finishing moving

It's awesome to have access to this technology. However, the main downside is the consumable cost (the brass wire). It will cost around 10$ cdn to cut one linear feet of 1/2" thick Aluminium. And 30$-50$ is it's steel. Is there a way to reuse the wire many times? How bad the wire get damaged with one pass? (off course, if we avoid crushing it in the final gear). Only keeping the new wire for final perfect finishing. Maybe two different wire size?
