  Attatchmets and Uploads an'at (Oh my!)
Posted by: mr_intensity - 2018-01-09, 11:35 PM - Forum: Site Discussion - Replies (12)

So, when I first joined (a few days ago), I went to upload my Avatar for use on the site, and could not find a way to do it.  I could only point the site to the address of an existing Avatar on the Internet.  I don't have an existing Avatar on the Internet.  Now what?

Next, I was having some problems with OpenSCAD, and have generated some test cases, and was hoping I could find some people to play with them.  So, I decided to post over in 3D Printing Software.

My test case code is less than 50 lines of OpenSCAD code (which is easy enough to post as "code"), and a *.DXF file that is 1.5MB.

First, I could not attach the *.DXF to my post, because it is an invalid type.  I figured I would rename it with a *.TXT extension, and attach it that way, but then it hit the size limitation.

I ended up canceling my post.

So, now the questions:

1) Any way to upload my Avatar to the site?

2) What are the valid "types" for attachments?

3) Does the site support attaching a *.zip, or other compressed file?  Maybe I can get under the size limit via compression.

4) Was 3D Printing Software the correct forum to post with my issue, or was 3D Printing Help the correct forum?  My problem is actually with OpenSCAD, which is 3D CAD software, so I thought the Software Forum was more appropriate.

  Snappy V2.0: Land of confusion.
Posted by: mr_intensity - 2018-01-08, 02:00 AM - Forum: 3D Printing Help - Replies (17)

Apologies if this gets longish.  I have not yet built, and have many questions.

I am planning to build a Snappy V2.0.

First problem:  I need a 3D printer to print the Snappy parts.  Oh, I guess I should mention (for those who are not aware): The Snappy is a **true** RepRap.  Literally, the entire thing is 3D printed.  You need motors, electronics, a bearing, and a couple of tiny nuts and bolts, and that's it.  Everything else is printed.

Anyway, I have a friend who bought/built a 3D printer kit, and is happily printing.  So, I am going to approach him with all the STL files, and the filament (around 2.4KG), and see if he is willing to help out.  As for the other parts, I am scavenging an aborted OneUp kit.

Second problem:  My OneUp kit came with only four NEMA17s and I need five for the Snappy.  I believe that the motors that came with the OneUp were Wantai 42BYGH610 from China (cannot confirm - hope we get the old fabric8r contact back soon). I would like to have all the same motors, as I think it simplifies things.  However, the 42BYGH610 is hard to find.  A set of three is for sale on eBay ($33 - pricey, as I only need one).  aliexpress.com has the motor advertised by (I believe) the manufacturer, for $8.95, but says that it is no longer available.

Another option would be to simply use a different NEMA17 for the fifth motor.  mpja.com has a motor who's specs come close:

Model:  32177 MS
Step:     1.8 degree
Lngth:     1-7/8" (47.625 mm)
Coil:   ~6 Volts/??? Amps/7 Ohn/15 MilliHenrys.
Wires:  4
Polar:  2-Phase, Bipolar
Torq:   ???
RI:     ???
DT:     ???
Wt:     0.75

Model:     42BYGH610
Step:     1.8 degree
Lngth:     40 mm
Coil:     6.5 Volts/1.2 Amps/6 Ohm/13 MilliHenrys
Wires:     4
Polar:  ???
Torq:     3000 gcm (41.662159670238 ozin)
RI:     54 g(cm^2)
DT:     220 gcm (3.05522504248412 ozin)
Wt:     0.24 Kg

Abbreviations:  RI=Rotor Inertia, DT=Detent Torque, Wt=Weight

So, this leads to all kinds of questions.  First, how does my RAMPS board know that one motor (which I will probably use as the extruder motor) is different?  Do I have to configure that in the firmware?  Is there a good tutorial out there for configuring firmware for differing motors?  Is it wise to even have an oddball motor in this scenario?

Also, I am planning to use the anubis print head that came with the OneUp kit.  Anybody have any hints/tips for using that head?

If anyone can verify the motors, or if using one oddball will help/hurt, or can offer any advice on this endeavor, please advise.

Thank you all in advance.

  Activation Email may contain a warning
Posted by: Administrator - 2018-01-07, 10:40 AM - Forum: Site Discussion - No Replies

Hi All,

If you are using gmail, and perhaps other email services, you may have noticed that the account activation email that you receive from this site includes a warning like:

"This message may not have been sent by: fabric8rsite@gmail.com"

This occurs because the email is actually coming from the fabric8r.com domain, but is claiming to be from our gmail address. Google recognizes this as a problem because this is one thing that people do when they are trying to impersonate someone else in order to get you to give them information. For example, if the email came from some random domain, but claimed it was from 'accountmanager@yourbank.com', then you should be extremely suspicious.

The fix for the problem would be for us to use Google's email servers to actually send the message, instead of sending from fabric8r.com. Sounds easy, right?

Well, it is. Except for one small detail. Our current hosting provider does not allow us to use Google's email servers with the hosting package that we have. They have a good reason - if they allowed that, if any site hosted by them started sending spam, they would eventually be blocked - and that would affect any other site hosted on the same server. So to protect all of their customers, they don't allow it.

What I will have to do instead is juggle our email addresses such that the activation emails don't claim to be from our google email anymore, but the address that does send the email forwards all replies to the gmail account. Sigh - also not hard, I just have to do it.

In the meantime, the warning text will still appear in the email. In this case, we are claiming to be ourselves, not someone else, so the warning may cause concern for no good reason.

  Rafts?

Hello,
I'm a rank newbie to 3D printing.  Just got a Creality CR-10.  Quick question: What's the point of rafts on the base of the prints?

  Moment of Inspiration
Posted by: MisterAcoustic - 2017-12-15, 12:30 AM - Forum: 3D Printing Software - No Replies

Hi All,

Just checking - are there any users/owners of the Moment of Inspiration software out there that would be willing to talk about it here? I just became aware of it, and it seems awesome. It's a supposed 'cheap' option for what it does, at nearly $300.

I thought I'd let everyone else know about it, and maybe figure out if I should start saving my money to pick up a copy.

  New guy with ThreeUp startup issues
Posted by: ChuckP - 2017-12-08, 06:46 PM - Forum: Q3DPrinter (formerly QU-BD) Specific Discussion - Replies (12)

Found a ThreeUp kit deeply discounted which became my birthday present. To say that this is a low price entry level printer is certainly an understatement.

So, I've got it all assembled, Repetier talks to it, and I can slew it manually on all 3 axes. Alas, the extruder drive seems to be dead. By way of troubleshooting, I've done the following so far:

  • Swap the connection to another axis. Manual slew of that axis moves the motor as expected.
  • Swap the driver bridge from a known good axis. No motion on the extruder, works ok on the other axis.
  • Examining the RAMPS/AT-Mega assembly revealed 2 pins bent so as to lie on the outside of the header. Put them back in place, but no change in operation.
I'm going to try moving the connection to the Extruder 2 slot to get some functionality. If that doesn't work I fear my RAMPS board will need repair or replacement. Does this sound like I'm on the right track?

  Creality3D CR-10
Posted by: MisterAcoustic - 2017-12-08, 01:57 PM - Forum: Filament Printers - Replies (7)

Hi All,

As I mentioned in the General Discussion forum, I just ordered a Creality3D CR-10.

So, I decided to start a thread about it, in case anyone already has one, or knows something about it. Feel free to chime in. I'll post my updates here once I receive the printer. I'm looking forward to buying a lot more filament Smile

  First posts now require Approval
Posted by: Administrator - 2017-12-08, 01:49 PM - Forum: Site Discussion - No Replies

Hi All,

In addition to the draconian registration approval process I've already implemented, I have now added the requirement that a users' first post have administrator approval.

So, if you have just registered, please be aware that your initial post may not appear right away. I will approve these as soon as possible.

I just don't want to fight forum spammers if I can avoid it. Sorry for the inconvenience.

PS - if anyone who registered prior to today has a problem with posting, please contact us at our gmail address ("fabric8rsite"). Even if you did previously register, but have not yet posted, your first post will need approval.

  Hurry! Great printer on sale
Posted by: MisterAcoustic - 2017-12-07, 01:33 PM - Forum: General Discussion - Replies (4)

Hi All,

I'm spamming my own forum here Smile. I just found this flash sale. Actually, first I found several different people saying excellent things about this printer that I had never heard of before, called the Creality3D CR-10.

Then I went looking for it, and found it on sale. It's a fairly large format filament printer. The price? $299. Build volume is 300 mm x 300 mm x 400 mm (~12 in x ~12 in x ~16 in).

The sale is only valid for the next 14 hours or so.

EDIT: Link removed, bad shipping price, see below.

Good luck. Just leave one for me.

  Moose in the North Woods
Posted by: Mooselake - 2017-12-05, 03:31 PM - Forum: General Discussion - No Replies

Semi-retired moose, fascinated by CNC machines, likes tasty browse, tends to run on.

Started off as a little moose ..... worked my way through EE school when my constant companion was named Sly Drool, as a programmer.  It stuck, did a whole lotta stuff including mainframe systems programmer, real-time software development (mostly networking, data communications, embedded device firmware), ran a dial-up ISP, etc.  For a mid-life crisis retired and went to paramedic school, worked in EMS (despite the original sales pitch, it doesn't stand for Earn Money Sleeping) for almost 20 years. Semi-retired these days, service's IT guy and occasional medic shift.  Married a long time, raised 3 daughters, live on a small farm a hundred miles from the nearest Home Depot.

Started with a small CNC router in the mid aughts, before arduinos, using LinuxCNC. Had 3D printers since 2012, a cheap chinese K40 laser for a couple years, and currently building a Maslow CNC router (actually, building the shop to build the Maslow, out of room).

I've been a mod (as in moderator) on several 3D printer forums including this one when it was QU-BDs, like to mod (as in modify) 3D printers and similar devices, and have way to many hobbies.
