For the high speed vacuum, why not just use an external tank, with plumbing
valve or equivalent to switch to whichever has highest vacuum?

The current resin I use has a 50 second gel time. Its a little like flying

I wonder if a person could make a inlet control valve with a piece of
tubing and clamp, or special clamp? Something that would take about 15 psi
forward pressure to open
Richard,
sure it can. All you need is to provide some level shifting (BBB is 3,3V,
gecko takes 5V iirc) and connect them.
Or you can use an existing cape: BeBoPr, Replicape, etc
Or you can wait a bit on a parport cape I'm currently working on..
(schematic mostly done, layout in the works..)

Hi,
I have seen a bunch of info on using BBB with capes and a lot of 3D
printing specific stuff like Replicape and BeBoPr++.
My thought was can the BBB replace the PC in LinuxCNC and drive the G540
directly?
The gecko will happily work with

Did a vacuum pour test. Complete failure as far as I am concerned. The
small amount of air introduced in the connection, as well as the small
amount of air in the mix becomes an instant mini volcano.
One option that could work for me is a double pour. Does polyurethane
water tight seal on cold

That's fine if you have the space and funds for a big tank, and a good
vacuum pump. I bought an old but excellent
