The Midwest RepRap Festival 2017 is coming up soon, and I intend to have this machine there. Come on out and check it out. It's local to me, so how can I not go, right?

I'm making a couple of changes to a special version of the machine for MRRF 2017. It starts with a new way to do the syringe. Not sure how this is going to work out, but it'll be ready for a test in the next week or so.

What I'm doing is moving the syringe up on top of the machine. I'm doing that because the single biggest hassle in making a run on it is pissing around with the tubing that goes from the syringe tip to the emitter. You need to make sure you have the right type of tubing for the solvent you are running, getting it cut to the right length, and threading it into place. There's also the cost factor. It ain't much, but if we can get rid of it so much the better.

The syringe is going to be mounted on top of the machine, with the needle sticking right down into the chamber. No tubing at all used. :)

The syringe mount swings out of the way to load the syringe, and a mechanism locks both the syringe itself down firm and keeps the whole assembly in place during the run.

There's a few more pictures on the projects website at OpenESpin.com. Go to the last couple of pages on the porfolio/inprocessbuild tab to see them. More details as I get it polished off and run a few trials.
