HammerBot Build Office Hours - Thursdays Nights in Feburary

[Otto Hammersmith]

Ok, decision made.

I'll be at my office in Cary building the HammerBot this Thursday and the test of the Thursdays in Feburary.  I'll be there, at least 7-10PM, it's not the only time I'll be there but I'll be there, then, for sure.

Anyone interested in joining me to lend a hand or work on their 'bot is welcome.  I have tools to lend, but we'll have to share.  If you have stuff like a soldering iron, bring it.

It's at 302 Davis Grove Cir, Cary, NC, #6012.  The front office closes at six, so you'll have to come in the side.  Fortunately we're right next to the door and have a window facing the outside.  Come up to the door facing Davis Dr. and knock on the window.

Call me if you need help finding it.  919-336-2873.

Let me know if you're coming, but no need to be RSVP or anything formal, like that.

[Otto Hammersmith]

I'm hung up at work, if you were planning on coming out let me know so I can let you know if I have to pull the cord on my own build party.

[Jeff Crews]

I couldn't make it today anyway; too much stuff happening. I hope to make it next week. JC --- On Thu, 2/10/11, Otto Hammersmith <otto.ham...@gmail.com> wrote:

But if you name it "Mr. Robotto," what will you do when the Z-stage "Styx?" Ooh, my side. I kill me. BTW Aoife, since Otto mentioned the name "Otto-bot," you're sort of required to design a new Autobot logo that looks like him. --- On Fri, 2/11/11, Aoife Hammersmith <aoif...@gmail.com> wrote:

Otto-bot just seems so obvious.  I suppose of said logo design was really, really good...

Planning on Thursday build night, again... anyone coming?

[Jeff Crews]

No response on the "Styx" joke? Wow, tough room. I really hope to get there this Thursday. It all depends on how Chrissy's writing is going. JC

[Otto Hammersmith]

I couldn't beat it, so the next best thing was to ignore it. ;)

[Jeff Crews]

Oh, I see. Well, domo arigato then.

My deep, deep, feelings of intimate lust toward puns of all kinds had incapacitated me.

that or I forgot to reply… one or the other. :-p

Either way, my cackling scared the cat.

I liked it and was laughing. On the inside.

Don't think I'll be able to make it this Thursday.

Barring alien invasion, mutant hamsters, monomaniac managers, herniated discs, self destructing miter saws, Aspergered coworkers, blown engines, overwhelming body order, general malaise or clogged nozzles, I'll be there.

[Bill Culverhouse]

Is the thur office hours still on?

Also my body overwhelmingly in order. :)

Planning on it, heading over there soon, though I may find myself distracted by a different sort of robot... craft robo showed up today. :P

[Otto Hammersmith]

Oh yeah, are you the one who left me a 30 second blank voicemail?

[Drew Nelson]

That would have been me.

[Otto Hammersmith]

I'm gonna have to cancel next week's, but got stuff organized last night and picked Bill's brain. :)

[Jeff Crews]

I'm in a bit of a funk regarding Big Red, so I need to shake stuff up and do some upgrades. Sooner rather than later, so I'm willing to buy some parts or entire extruder/rod kits, etc. So, Bill et al, what's the first thing you'd do? Upgrade to a Wades (or MB now has a "stepstruder," but direct drive from a NEMA17? I am dubious), put in a set of Acme rods, or sidestep that with a Z-rider, or whut? I'm open to suggestions, and suggestions for sources as well. JC

[Bill Culverhouse]

Depends on what you consider you biggest printing issue.

 

If the Z-wobble/binding is still a show stopper, then Acmes or z-rider

(did he ever finish the instructions on that thing?)

 

I do recommend the stepper upgrade. I have the makergear and it is great.

It is silent and never gets hot, I don't know why the hell MBI feels the need

for direct drive, that's why their new "invention" gets so hot.

 

Not a fan of any of MBI's current innovations. The MK5 is ok but the hot-end

is ridiculous overkill. My makergear heats up in 20 seconds and I don't need

a relay. The new Z-Stage is better. But the stationary extruder kills the build area.

 

I would say:

1. Stepper Extruder.

2. Z-axis upgrade. (z-rider or acme)

3. x-y upgrade. (bearing lowrider) 

Or say screw it and build a prusa.:-)

 

How far did you get with the holiday prusa?

 

-b

[Jeff Crews]

My biggest issue is the urge to play around. (that's what she said...) After that I'd say it's the occasional extruder stalling issue, which is prob. the need for a new idler wheel. I think I'll just go to Makergear. After that I'll look into the Z-rider. I have the parts for the original Mendel, I just need to move forward putting it together. I only printed a few pieces of the holiday Prusa before extruder issues and lack of holiday spirit derailed me. JC

I decided on a Wade's and now I'm flippin' confused. they're saying that I need a Polulu stepper driver? I thought the main extruder board would work a stepper by connecting all four motor outs? I'm okay with getting a kit and even hobbing the bolt if I have to, but I'd rather not order a new driver board.

[Bill Culverhouse]

I have an extra MBI driver. One note tho it makes the motor run hot-ish.

You can run it off the EC using the two H-Bridges with a special firmware.

That makes the motor run very hot. You might can play with the drive voltage

of this MBI driver to keep the motor cooler. The pololu driver runs cooler than

the MBI's version.

 

You don't really need the microstepping that pololu offers for the extruder.

 

What kit are you getting?

[bill]

Made any progress?

I meant to mention that I have an extra acrylic "middle" if you want
it.
It helps a bit on the vibration noise of the x-axis motor (The loudest
motor on the makerbot) by replacing the wood "middle" board (which
acts
like the sound board of a violin) with a much more ridged plastic that
dampens vibration.

Jeff, I'd offer it to you but you do have to take the bot *completely*
apart
to swap the piece in. If you'd like one I'd be glad to cut one for
you.

I've gotten nowhere.  I broke my big toe (exactly a week ago, five minute ago) and have been laid up.  You'd think 'bot building is something one could do with a broken toe... and you'd be right.  However, not sure I trusted my vicodin-addled brain with the task. 

I'm happy with it, though, I've come to terms with a million half-finished projects.  They'll be done when they're ready to be done. :D

[Jeff Crews]

Ow. Are you going to be in the Build Office this Thursday? jc

Nope.

We're dropping that office, they were adding a new insurance requirement that was, in effect, adding 20% to the rent.

Probably won't have a build night this Thursday.

[Jeff Crews]

Hey- I am going to put in a McMaster order tomorrow (sunday) to ship Monday. Anyone want anything? JC

[Bill Culverhouse]

I'm good right now.

 

What are you getting?

I need some wider/thicker Kapton tape.

Don't need anything tho may have kapton tape ... got 2 different thickness rolls in my 'bot kit.  Haven't gotten far enough to know whether I need it all tho.

Either way, you could have some if you wanted/needed it this weekend and lend it back if I needed it when I got that far.

[Bill Culverhouse]

The wide ~1" stuff is used to assemble the PET belt for the ABP. I

understand that the failure rate of the belts is such that you will need

all of it. :-) That doesn't mean there isn't enough to give some out.

I think a lot of people give up on the ABP for anything but small prints.

 

Where is a good place to get precision rod? I was going to go to

Fastenal but I know they are much more expensive. Is McMasterC

a good place for that? Where are the robot people getting their stuff?

 

Also I have a 4"wide roll of CCK (cheap chinese kapton) coming in a

week or so. I'm told ABS sticks to it like glue.

[Peter Charles]

Jeff-

I could use 2 of the 5779K782 (6 position nylon Manifolds with Push-to-Connect Tube Fittings) at $18.55 each. One 36" rod of 8974K153 (6061 Aluminum rod, 1.125" dia) at $20.66, and one 13" rod of 8916K27 (aluminum bronze alloy 954, 1.25 OD, 0.25" wall thickness) at $36.11. All are in stock, and available for shipping tomorrow. That's about $100 plus tax and shipping. If you don't want to add all that to your order (gonna kill your shipping), let me know and I'll place it myself today.

Thanks!

Ya, appreciate that muchly. Don't want my stuff alone to make shipping crazy expensive. If most folks are ordering small things, best for me to just place mine alone. You have a better idea of the total order than I do, so I'll leave the call up to you, JC.

JC-

did you include my tons of metal in your order?

peter

[Jeff Crews]

Ugh. Haven't sent it yet, tonight has been a little crazy. I'll let you know. JC

[Jeff Crews]

I just ordered my tape. I should have made up a whole order of stuff for my Mendel but Chrissy is in dissertation overdrive, the FabLab truck just arrived, I have to get my bot working well by Friday for Ping Fu, and my brain isn't working for shit. ugh again.
