It really is a great machine and if you can somehow manage to build it, it is really very satisfying when it produces your workpieces. I can't thank Ben Fleming enough for this!
Love your videos! I appreciate planning the layout of the parts on paper before starting construction. When soldering, you want much finer solder, and to heat the joint and melt solder on the joint, not the tip of the soldering iron. The flux core only works right if it has a chance to act on the joint before it burns away. Recommend planning the airflow, fans blowing directly across the resistors, and putting the sensitive electronics of the PCB upwind of the resistors and other major heat generating components.
Sorry, I don’t wish to throw a spanner in the works at this stage of your build but actually a commercial grade EDM machine is easy and cheap to build, the problem is there is a misconception that there’s some sort of manufacturer’s design secret to these machines which makes people overcomplicate their home build designs usually by using some sort of code to control the actual burn. It might be worth you having a look at the video that I posted on here a few days ago in response to people having design problems which I think you will agree proves my point.
Can I use a different power supply than the transformer? for example dc dc booster? So what should be the maximum DC power? Is there a problem if 2 48 volt transformers are used?
I am not an electronic expert so I can't give safe advice. But I think how the DC is generated does not matter if it can deliver the desired voltage and current. Ben Fleming states in the book that more voltage is better and gives a more stable burn. If you are interested you need to order the book there it is described in detail.
I bought Ben Pulse EDM's book. One thing is strange, your circuit board has 4 mosfet transistors while the schematic in the book has 6. I look forward to following you to see the results obtained. My EDM was built following Robert Langlois' book and the results are similar to the EDM built with Ben's first book
Hi, I ordered the PCB from Ben Fleming and it is an updated version (2.0B). You get an updated description and bill of materials. It has several changes and one of the bigger changes is that it has only four mosfets.
I wonder if BAXEDM is also pulsed one, you can actually buy arc generator, it costs a bit though - 4.2k euro. I tried to find info of inner schematics of it but haven't succeeded, but anyway its a cool project, just a bit pricey.
Fantastic video Looking forward to the follow-up. May I ask could you publish the BOM list and the supplier's details. The case looks very robust and massively over engineered,did you design it in cad software. Thanks for taking the time to make the video and share.
Yes, you are right the case is a bit overkill but its the cheapest and easieest way for me. You can see the scratches on the sheets because they are old and used and from my spare parts bin. I can also easy tap and cut the aluminium what is a bit nasty on old steel computer cases (I use old comuter cases a lot- look at my cnc control videos). Sorry, but I dont know if Ben Fleming would allow to copy his nice work - it is copyrighted material. If you are really interested you need his book anyway. Thanks for your nice comment and best wishes.
Hi. What was the total price for you to build this machine ? I am choosing between buying a Chinese $500 EDM machine from aliexpress and doing some upgrades like better power supply, etc. Versus building from kit like you just did.
Hi! Can you please send the link to the "Chinese $500 EDM machine from aliexpress" that you mentioned? I've checked aliexpress and found nothing like this

Clamping capacitors firmly around their circumference can be problematic. Capacitors change in diameter with heat and age. Better to support them by their leads, or with sealant / adhesive in a couple spots.
Thanks for this valuable tip. I should have known this but but to getting ahead sometimes I work faster then I should. I will change the fastening of the capacitors as soon as I replace the exploded resistors. Many thanks for your help Ralf
@@myengines2443 The work you do is quite impressive and I now hold you in even higher regard for taking my advice - graciously, where many would have lashed out.

I purchased the book couple years ago and i am still postapponing but i am happy to see someone who engaged in building the ben's pulse one

Very interesting build! I look forward to future videos, keep them coming ;)
if you are looking to do "wells" in Al you can use a square broach on a quill or z axis to finish the corners from a 1/2" endmill.
Many thanks for your kind comment, as soon as the missing parts arrive and I get some results I will make a new video.
Greetings
Very neat and well thought out construction - look forward to further videos.
Thanks
Cool project, thanks for sharing
Thanks
Nice work, looking forward to see the final result 😇

Hi Scott, thanks for your suggestions.
The fans are sucking the air out of the case and I thought the air flow (maybe with a few guiding walls) is ok.
Very incredibol my friend! 👏👏👏👏👏❤❤❤🙌😊😊😊

Hola !! Donde puedo comprar los libros de Ben Fleming ???
I tried a plasma cuter , didnt do so well as a power supply , electrode kept sticking
Can I use a different power supply than the transformer? for example dc dc booster? So what should be the maximum DC power? Is there a problem if 2 48 volt transformers are used?

500 Dollar is a good estimation of the cost of the machine but depends on your claims and your existing parts.

What are the advances in the Stirling engine? Have you been able to improve efficiency?
Hi,
at the moment I am improving my workshop but hopefully I can soon return to Stirling development.
Many greetings and keep up your good work.
