hi group

[mathisyo...@yahoo.com]

I've been working alot and trying to make plastic stuff too. not much
activity on this group lately but there's alot going on with the main
group. any interest in a november meeting? as far as printing I've got
my ToM printing at .2mm layers and I'd like to push it further. also
I'm interested in seeing how people are liking the mk7.

[Aaron Double]

Not sure about the MK7 since I'm playing with the MK6 dualstruder.

About the meetup, looks like I can meetup on either the 9th or the 16th (both are Wednesdays) and I can host in East Boston.

Aaron Double

[Jeremy Green]

I have a mk7 that should be working by tomorrow. Either of those dates should work for me.
I also have a hot end that I've been working on that should be able to get the nozzles 10mm apart. Now i need to figure out the drive system.

[Aaron Double]

If you shoot me some images and specks, I can probably give you a hand.

Aaron Double

[mathisyo...@yahoo.com]

I saw you were working on the 2 headed mk6. I'd love to see it. I
believe those dates work for me. how was the last meetup?

It was cool, small, just Jeremy, Chandra and I.

We worked on tuning Chandra's stock cupcake and Jeremy's flip over to 5D skeinforge.

how long did/will the mk7 take 2 install? I'm thinking of getting
one. I reposted a question I saw elsewhere on the main board a while
ago about the possibility of setting up an easy way to quickly swap
btw mk6 and mk7. is this feasible?

the way the MK7 is designed, it's like a super simple build. Once its assembled, the most annoying thing should be opening the bottom cabinet of the TOM to plug it in.

[mathisyo...@yahoo.com]

thx. I think I'm gonna give it a shot.

It took me about 1/2 hour to put it together. I got some thermocouple connectors from mcmaster carr and am planning on putting connectors on all of the other wires so that I can swap it easily. The one issue is that the stepper is different so the ref voltages would be different on the driver. I'm probably going to have two drivers installed, one for each extruder and just swap the connectors from the motherboard to the drivers.

-Jeremy

[Aaron Double]

I'm using the polulu drivers, much easier with only one pot on them.

I'm planning on going to the motate system when it's up. the pot is controlled by the chip and the chip can recover from skipped steps at 128th step.

hehe, here's a teaser image of the dev carrier board.

Aaron

[Jeremy Green]

Maybe I'll do that soon. I haven't drawn it up yet. I've mostly been designing it as I machined it.
My plan is to use the mk7 nozzles.
With the 6mm nozzle hole 1mm from the edge of the block, that makes the center of the nozzle 4mm from the edge. A 2mm gap between the blocks seems like it should work.
The only worry I have is whether I can drill a 6mm barrel with a 3mm filament hole. It might end up a little fragile.
I'll try to draw it up sometime soon. It's pretty much the same as the mk7 setup, in fact, you could mod a mk7 block by just shaving off a mm or two from the side of it.

-Jeremy

[Aaron Double]

You'll be mounting them head to head, right?

[Jeremy Green]

Probably though that doesn't leave any room for a bearing. If it was get drive I could mount it side by side either by having the gears on opposite sides or by spacing one set out from the extruder a bit so they are staggered.

[Ada Aimua]

Hello,

I am selling a few of my electronics items and I was wondering if anyone wanted to purchase?

Sparkfun Inventors kit w/ hard case: $75, OBO

Lenovo Thinkpad X60: $170, OBO

Drafting table (white), $30, OBO

I can be reached via email or by phone (978 710 9286). Let me know!

[Aaron Double]

Word on high (my wife) has given me freedom to geek out on makerbots on the 16th at 7:30pm

Does that work of others? The studio is in East Boston a couple blocks from the exit of the Callahan Tunnel.

Best,

Aaron Double

[Matt Micari]

Hello Aaron! I'm looking forward to the meeting. I'm just starting out with 3G printing. I haven't done it yet but have been designing on google sketch up.

Is there anything I should bring to te meetup?

Can't wait talk shop

-matt

[Aaron Double]

Umm, I would say to bring your makerbot with you, then if there is anything you need to help tweaking, it's there and ready.

Best,

Aaron

[Neal Orman]

I haven't had a lot of time to work on/with my bot recently, but I'm definitely interested. See everyone on the 16th!

 -Neal

[Aaron Double]

Hey Neal, 

Thought you might be interested, I need to model up a wedding cake topper that is made out of two Twonkys.

Aaron Double

[Aaron Double]

By the way, does anyone want one of Rob Giseburt's PSMDs or 3G 5D boards?

I can get him to get them to me by the meetup.

Aaron

[Chris Connors]

I'm in!

Yes, it is a garage, the left garage door is the one you want. It's pretty funky inside, thanks to my studio mate Matt who could lightly say likes planes...

Aaron Double

[Jeremy Green]

I can make it. Sounds like it will be a bit bigger meet up than our last one...

-Jeremy

[Aaron Double]

We actually should be fine for space.

I should be able to get there at 7pm. But I would shoot for 7:30 to arrive.

You guys have fun tonight. I'm stuck here doing stuff I'd rather not
be doing (whine whine).

[Neal Orman]

I'll be heading down this evening, likely will be a little late (closer to 8). Realized I forgot to bring some alcohol to clean my build platform and probably touched it in transport. Anyone have some wipes, etc they can bring tonight? Otherwise I can pick some up on my way.

Also bringing my makerbot on the T is always fun - I got asked if it was a flux capacitor this morning.

 -Neal

[Aaron Double]

SCIENCE!

Heh, we are meeting in my studio, don't worry about bringing alcohol. 

Aaron Double

[Chris Connors]

I'll be heading up to Lynn to check out http://www.exclrecycles.org/about.html, and then heading back down to the meetup.
Two sad bots will be joining us.
Chris

[Aaron Double]

I have a psu for you.

Aaron Double

[chandra bajpai]

I've got kid duty tonight....will definitely make it out next meeting.
