>hollow tube
this is precisely why I have based most of my electrodes for initial testing on brass tube.
I'd just need a pump and preferably a pump that is reasonably sized and a means of regulating or controlling the flow. Mind you I'm dicking around with lamp oil on a 3d printer. I dont want a huge mess. Which is why I'm currently not using the pumps I have around. Also I need to avoid getting carried away with doing too many things outside my works scope. A little is fine and good for my sanity. Also playing with the thing often makes you think more than rewriting the same formulas for the nth time.
You see I could probably rewrite marlins planner. I even have made a feedback loop for a standalone ram using a window comparator, stepper driver and stepper. I could get an USB isolator. I could be touching off tools and all that.
But I need to focus on doing the bare minimum to get a stable spark gap that I can use for development of the PSU. I once even considered just blasting film capacitors. Should make for a pretty decent spark gap the whole time until burnt up.
>Rack robotics
Last time I checked, they and many others ran open loop. Wire EDM seems to be very forgiving in that aspect but I am sure you're leaving alot of performance on the table.
>Negative feedrates? How does this work? Say you program an arc, the planner runs an arc and half way through you get a short. You can't wait for the next line of code, you need to break here, which is possible with conventional G-Code and then? Issue the same arc again with neg. feedrate? I think the planner should handle this.
>Schematic
Like I said, there will be a whole schematic, preferably even build manual, in 3 months. I am generally opposed to the idea of (((intellectual property))) and this wont be an exception. But until I have handed my thesis in it's my academic capital.
>employed
I was employed by my uni before, but a different lab than the ones im working with now.
