What up my maker!
Rod from Goshen. I visited a meeting a few weeks ago but had to leave early. I'm a mechanical engineer, used to work with Brian VanBlahblahbos at Lucid Energy until Lucid Engineering up and left to move to Portland (I lived there a year and-a-half without my family, returning a year ago). Apparently the MakerHive met for a while in our old shop... sorry about the mess... I sat in on a meeting when you were at the old Electric Brew before that, stopped in at SeeMeCNC when they were doing Prusas (I guess it was). It's hard sitting in on meetings where everybody has cool shit but you don't.. :-) Been wanting to build a 3D printer ever since...
...so I am. Initially I was going to build the Taz fork that the Peoria guys have developed (the "z@" - met Joshua in March at the fairgrounds). But decided to start a bit more basic and with printer with a larger knowledge-base so I'm building the Prusa i3 Rework (aluminum plate version. Is your Graber THAT Graber, btw? ...if so, sorry, man...). I got the Makerbot Z18 at work running and am on my last batch of printed parts for the i3. The last of the rest of the pieces I received yesterday, so I'm hoping to start assembling the frame Thursday night so y'all can laugh at me :-) But seriously, would appreciate any advice. A couple tweaks from standard are using the E3D V6 hot end, somehow bonding a sheet of soft copper (left over from a past project) to underside of the glass, and putting silicone tubing standoffs spaced apart and between the Y-carriage and the heater PCB to hold the heater against the copper and to act as the table Z-adjustment springs. Also seems like the Greg's extruder might be suited to G2 pulley and belt instead of the printed gears.
I just hope the Chinese RAMPS stuff I bought off eBay works. Trying to figure how they can sell a [knockoff] Mega2560, RAMPS, servo drivers, graphic display, limit switches, two GT2 pulleys, belt, and MK2b heater for, umm, $60, free shipping from Utah (not China). wtf.
My actual end goal for the i3 isn't really to build the i3 but rather use it to better understand 3D printing and try out a couple low moving mass printer ideas- one with a Bowden and hot end doing X-Y on a carriage riding on air bearings and moved in X-Y via three belts to stationary servos and a similar one with a pendulum carriage which would print semi-spherically with similar belt/servo arrangement where the equivalent of cartesian Z is radius. Basically just for the challenge of seeing how fast I could print. I assume that the moving mass is the dominant factor for print speed?
'
Also been learning Arduino programming the last couple months both for work and fun. I haven't really done any programming since BASIC when I was in elementary school in the early '70's- that was on a monster HP machine in a big cabinet in a hot room with 16K memory, two teletypes and punch tape.
See you tomorrow. If building doesn't match the agenda for tomorrow's meeting, please let me know.
Rgds, -Rod
