3D Printer?

mandark1967 Re:I have three 3D Printers (173 comments)

TLDR; Rank
1 - Creator X - Lots of Media options, Dual Struding works extremely well, Great support from company
2 - Rostock - Greater Build Area, Faster printing, Cool-Factor
3 - Replicator 2 - Ease of Use

If you don't mind the "20+ hour Assemble and Tweak" process and you need the largest build area, the Rostock Max is the best option of the three because it has a larger build area and can print a little bit faster than the other printers. (though my dialed-in Creator X can print hella fast) And, like the Creator X, it can handle ABS/PLA/PET/Bridge Media. I'm currently designing a M-ITX computer case while I tweak mine. NO DUAL STRUDING unless you replace the print head with a dual extruder and re-calibrate everything

If you don't want to take the 20+ people-hrs building one, the Creator X is the best choice. I had issues with mine because it arrived damaged and it took a while to get fixed and dialed in. The support from Flash Forge was fantastic. They stood behind their product and I can't say enough good things about them. This is the one I use most now. Mainly because I am doing a lot of Dual-Struding. (Using both print heads on the same print) It's dimensionally-accurate (to sub 1mm) and I use it mainly to print Legos, motorcycle parts (Clutch/Brake Levers) and multi-color Common Access Card (CAC Card) holders which hold 2,3, or even 4 CAC Cards (NFL Team Colors, Blue & Gold for Navy, Red & Gold for Marines, Pink & Pink for Air Force pussies.)

I bought the Replicator 2 because it was my initial foray into 3D printing and I wanted an easy to use printer. It is "set it and forget it" easy to use. So much so that you should probably expect a call from Ron Popeil when you click "Print". Within 2 days of unboxing it, I started a 29 hour print project and never worried that it would mess up partially through the process.(which can sometimes happen with ABS due to temperature differentials in the piece being printed if it's relatively tall) I don't recommend it though due to the high investment and the mfgr's policies regarding support.

3D Printer?

mandark1967 I have three 3D Printers (173 comments)

I have a Makerbot Replicator 2, a Flash Forge Creator X, and a Rostock Max Kit (under construction)

They're fun to use and I've learned a bit of 3D Modeling, to boot.

Heathrow Plane In Near Miss With Drone

mandark1967 Re:It won't be long (325 comments)

Technically, the risk of flying a plane into a building in New York wasn't zero before 9/11 not because, "although it hadn't happened, it was possible", but because someone already flew a B-25 Mitchell bomber into the Empire State Building

SpaceShipTwo's Rocket Engine Did Not Cause Fatal Crash

I'll tell you exactly why it crashed. It hit the ground before it was supposed to. When it does that, it's a crash. Don't need no fancy, schmancy NTSB to arrive at that conclusion.

New Long-Range RFID Technology Helps Robots Find Household Objects

mandark1967 Potentially very useful (38 comments)

I work at a large organization where we have several thousand computers, most with dual monitors and other peripherals.

It would be very beneficial if this technology allowed us to perform our yearly inventories by simply walking through each room carrying a tablet or laptop which recorded the devices present in each room.

We could then see, easily, if any equipment (like secondary monitors) were moved from room to room without permission.

Interviews: Ask Bre Pettis About Making Things

mandark1967 Future Replicator 2 Upgrade Kit Plans? (69 comments)

I note that the Replicator 2 and Replicator 2X share many components.

Will there ever be plans to release an upgrade kit for the Replicator 2 which adds a more powerful Power Supply, Heated Build Plate, and/or a second Extruder Head Assembly?

It would be nice to be able to add those options to the Rep2 in order to print ABS and other materials, or to do multi-color prints.

Follow up Question relies on the proviso that an upgrade kit is planned....

3D Printing: Have You Taken the Plunge Yet? Planning To?

mandark1967 Wow there's a lotta negativity here (251 comments)

I didn't really think my submission was provocative but, based on the responses, it seems to have incited a lot of negativity for some reason...

I've had 1 part, and -only- 1 part "fail". That was due entirely to my design (I'm still a n00b, I admit)

My first week of ownership has been great, and I have recevied several requests to make items for, gasp(!), for real, honest-to-god currency no less!

I didn't buy it specifically to make money, but to learn and make things I need. I am also learning, however, that I "can" make money with it if I put forth a little effort...

Items I've made during my first week:

SSD Docking Station case
Dashboard to hold the speedometer/turn signals/ignition/GPS/Go Pro mount for my DR650
Fan Grills for my computer
Liliput 7" LCD back cover that mounts it into my spare drive bays in my computer case (so I can run my monitoring software there while gaming on my main screen)
Replacement door hinge kit for my Obsidian 800D Case
Wall-mounts for my surround speakers
Raspberry Pi case which also mounts a 4-port USB hub

I'm also currently in the design/prototype phase for a SFF HTPC Case.

3D Printing. Have you taken the plunge yet? Planning to?

mandark1967 mandark1967 writes  |  about 9 months ago

mandark1967 (630856) writes "With recent advances in working with different filaments (Wood filament, Nylon, etc) and price drops seen lately, I'm curious to know how many of you have decided to take the plung and get into 3D Printing. There are several kits available now or even assembled units that are in the same cost range as a "gamer" video card (DaVinci 1.0 for $499, Printrbot Simple 2014 — $399, 3d Stuffmaker — $499) I'm wondering if any of you have purchased one and how you like it so far. I've been in the computer field since the 80's but never did CAD work before so I was very hesitant to take the plunge, fearing the steep learning curve of mastering programs like Blender or AutoCAD. What I found, however, was programs like TinkerCAD and 123Design made it very easy to learn basic CAD so I decided to picke up a 3D Printer last week. After a week or so of design work and printing out many items, I think I've picked up a few skills and I can actually see myself making a little money on the side creating and selling items. I don't think I'd trade my current job for one designing and printing items, but it is nice to have a little income on the side if I choose to do that."

Our Solar system was adopted?

mandark1967 mandark1967 writes  |  more than 7 years ago Our Solar System is traveling at a 60 to 90 degree angle compared to the rest of the Milky Way Galaxy and scientists have now discovered why. It seems our solar system originated not in the Milky Way Galaxy, but in the Sagittarius dwarf galaxy, which is in the process of being eaten by the Milky Way.

The article here contains some very interesting information concerning the process of our solar system being adopted by the Milky Way and posits the theory that Global warming is a direct result of our adoption into a more energetic galaxy. There is additional information located at this link which contains further links to additional coverage.

Thermalright gone wrong

mandark1967 mandark1967 writes  |  more than 7 years ago

I received my Thermalright Ultra 120 Extreme Heatsink today and note the following:

I checked how "flat" it was. I did this by placing a metal ruler on it's thin side on the base from corner to corner diagonally. While I couldn't get a decent picture of just how concave the unit is, I measured a 1.5mm curvature. Meaning there is a 1.5mm hump in it at the middle of the base.

If this is some sort of design feature, someone needs to re-design the base. I did a search on Google and found WAY TOO MANY references to people having to lap the crap out of the thing in order to get it to perform better than the stock heatsink. Nearly every single user I found who is having quality control problems are encountering the exact same ones;

o The Heatsink, as designed, built, and delivered, provides no increase in performance over stock (until lapped)
o The Heatsink base is curved, not flat
o The Heatsink base has more grooves than Soul Train

The base of the heatsink looks like it was machined by Stevie Wonder.

There exists an area the seemingly didn't get machined at all. The grooves in the heat sink are so pronounced that I considered boxing it back up immediately and returning it. I decided against returning it immediately in order to see if I could lap the heatsink to an acceptable degree.

I started the lapping process by using 800 Grit due to how badly convex and rough the surface was, and then moved to 1000 Grit, then 2000 Grit Wet-or-Dry Sand paper. I used a metal finishing sanding block in order to maintain the flatness of the base. After 2.5 hours of lapping, I had removed most of the nickel plating in the middle area of the heatsink and some of the defects in the base.

Nickle plating? It isn't worth a penny if you have to sand it off!

While most of the nickel plating is gone, the grooves remain. You can really see the "quality craftsmanship" on display here. (Close your eyes and imagine the Dakota Badlands)

I lapped the heatsink base until I could clearly see the writing on my camera in the reflection of the base, but after this exercise I ran into another problem when mounting it to the motherboard, but it's not one you would initially expect.

I use a FDI LanParty nF4 UT SLI DR Socket 939 board and the unit doesn't come with mounting brackets for a 939 board. When I placed my order I specifically ordered a Socket 939 mounting kit.

When I attempted to mount the heatsink the screws wouldn't fit into the mounting plate on the back side of the motherboard. I tried many different options such as using the springs from the mounting kit on the stock screws and all sorts of things like that but I couldn't get it to fit at all.

I then went to Thermalright's website and looked at their instructions. It calls for replacing the mounting plate that resides on the back side of the motherboard with a metal one if you are using a DFI motherboard. My problem is that I don't have one and one wasn't supplied in the Socket 939 mounting kit I ordered. Did I mention Thermalright doesn't make one?

Final result? I'm stuck with a piece of crap heatsink that

1. Is "supposedly" the best air-cooled heatsink on the market (that)
2. Doesn't sit flat even after lapping (and)
3. Has grooves the size of river gorges (and)
4. Won't fit my motherboard

It brings me great memories when one my customers remind me of our Celeron overclocking kit, something that propelled us into the spotlight. I have meet so many wonderful people in this business, and I am grateful for the opportunity. Please stay tuned, as I am doing my best, to figure out a way to reopen PCNUT (any suggestions/assistance/donations will be greatly appreciated!)! Best Regards, Humphrey Chen aka Da HeadNut PCNUT Computers, Inc. They were the company that got me hooked on overclocking and I am saddened to see them close their doors.
