Open meeting tonight ... we'll present the new big additions to PS1's CNC suite, (on screen, not in person ... it's not QUITE physically present yet)
So come out, bring your project by all means
also ...
I'd like to sound out actual showing-up type people, local people that want to see cool CNC stuff as well as work on build projects, about how keen you might be to do field-trip meetings at other locations...
Right now, I'm talking about doing a meetup over at Analytics Lounge, which has a fully functioning waterjet and large-bed beefy-spindled CNC router. as well as some as-yet-unfinished refurbs of a couple of largish vertical CNC milling stations. (and, of course, the canning electron microscope, mass spectrometer and atomic absorption spectrometers that are a bit more sciencey than maker-related but unique and cool.
The other location I'm interested in getting y'all out to is 3403 West Grand Ave, where some folks have got an old Kuka robot from an automotive assembly line in Detroit up and running again, and may have an extra axis incorporated by the time we get over to see it.

Sorry to miss this meeting. On deadline with 2 projects. Attached is image of a piece i made on the multi cam at saic. Close to finish. News of kuka is very exciting!
typos are mine

At Analytics Lounge, the big CNC
projects are:
* CNC Router - They have an ATC spindle for it. The tool changer is pneumatic. They got a grant from Automation Direct for a whole bunch of pneumatic equipment, etc. It just needs to be installed and documented. I believe they're also going to build a vacuum hold-down table for it.
* Fadal VMC 4020 - This is a HUGE, POWERFUL CNC machine with a 21 tool changer and a 40"x20" work volume. As far as we know, everything is functional except the lube system. We don't think the ways are getting lube. The system should be pressurized to around ~200 PSI, and I've heard that the metering valves on the manifold that control the relative quantity of oil delivered to various parts can malfunction and may need to be replaced. But it is possible that there are other clogs further down the lines. I'd like to figure out what's up before shelling out money, if possible. We are kind of out of our league here and need help. Afterwards, well, we are not terribly familiar with actual CNC machining and we want to get Fusion 360 CAM working; people with experience here would be very much appreciated to get us started making actual parts. One project that I mentioned at a Fusion 360 Meetup: I'm working with Adler to build a CubeSat. I'd like to use this to make parts that we'll launch into low earth orbit.
* Fadal VMC 3016 - This is a smaller version of the 4020, with a 30"x16" work volume but a newer CNC controller. We attempted to disassemble the ball screw, the balls came out, and we're not sure how to re-pack it. At this point we're focusing attention on the 4020, although if this isn't a difficult task, we'd be happy to refocus back to this machine as we think the way lube system on this one works.
* Waterjet - It works great but could use improvement. This includes: Leveling the slats in the bridge. (We've got to position the nozzle Z height higher than we should on large jobs so that nothing collides.) Rebuilding the pump. (It's working now, but it probably should be overhauled.) Fixing the solids removal system. We have a camera that attaches to the head that allows for precision parts alignment that hasn't been installed. Also we believe we can hack this with a servo to allow for computer controlled adjustment of the Z axis.
We could really use help!!!
Ray also mentioned the canning electron microscope. He let the cat out of the bag. We converted the vacuum chamber into a pressure chamber so we can fill it with pressurized boiling water. So far I've been canning jams and jellies. It's really going to come in handy when it's time to harvest tomatoes.... ;-) jk....
