Need opinion on how, and if I can make a EDM machine with linux CNC :)

if i am going to buy an IO i would like to have the ethernet preferably less than 200$.

regards,
Tim

for power supply i am searching and it looks i might use a microwave transformer. i will rewire the secondary with multiple outputs as i might need.

for the steppers i have some 3d printer power supplies.

Tim

Tim,
Sit down with your favored 3D CAD and draw all parts and assemble the construction to see how big it is going to be before you start your journey making a WEDM machine. Don´t buy anything before this is my advise.

thanks a lot. i am in the process of making the drawings. for the process i will scrap a prusa i3 that i am not currently using and use the x axis as is. i will invert the Z axis "motor on top" and add bearings to support it vertically into the X axis. and put the Y axis on top so it will be all hanging from the top.

the mechanical stuff is not to difficult for me. i got a tig also if i will ever need it.

Tim

OK, I just can't see where you will get 300x300x300 out of a prusa i3.

How have you calculated the volume of the dielectric tank? The weight of steel in 300x300x300 is quite high and I do not think a prusa frame will carry that weight.

yep me too, i think 300 X300 is not realistic for my space. no i will not use that frame. i will make another one but the general mechanics will get the idea from it just will modify them for more weight.

Tim

i will try to make the wire move in the x y directions but it will make it 2x longer but will help with wire tension and very light as only the mechanics of the wire will be moving the object will not move. not the best setup but i can live with that.

Tim

it might add a bit of momentum by the wire that will be moving on the C arm but i think it will be rigid enough to overcome that. and the metal is not pushing back.


Tim

corners for the general structure will have 2 members in parallel for x y z. so in total 24 10mm threaded rods.

so this can be scaled to needs, also the 2 rods parallel to each other in x y z can act as supporting members for attachments on top for the x y and for the working metal fixtures near the bottom. plus it can hold more weight as it will be distributed among the 8 Z rods to the ground plane.
