Windows 10 UI Guidelines

2016-06-04T12:21:25Z

Rayharwood:

Normally I'd say "go search on MSDN" for guidance and examples for anything "Windows desktop forms" programming, but unfortunately the Windows 10 guidelines are either buried or mixed in with "old" Windows 7 information. Here's a collection of things I've found relating to a uniform Windows 10 User Interface.

=Develop Universal Windows Programs=

The biggest thing I've seen is the push to develop "Universal Windows Programs", which you'll see simply as UWP in many places. The idea of UWP is that your app can run on "anything Windows", including Windows Desktop, Windows Phone, Xbox, and HoloLens. For an interesting video presentation, see [https://channel9.msdn.com/Events/Build/2015/2-692 this Channel 9 presentation].

=General Windows 10 Guidelines=

There is a general document which is not specific to a particular version of Windows available: [https://msdn.microsoft.com/en-us/library/windows/desktop/dn688964(v=vs.85).aspx Design Guidelines] It contains images and descriptions relating to controls, commands, text, messages, interaction, windows, visuals, experiences, and the windows environment.

Budaschnozzle Removal & Replacement

For the Lulzbot TAZ 4 3D Printer

== Required Tools & Supplies ==

*2.5mm and 3mm Allen wrenches (from Lulzbot toolkit)
*Parts dish (empty)

== Removal ==

#Remove filament by heating hot end to filament temperature, retracting 10-20mm of filament, releasing the idler assembly, then removing the filament by hand, pulling upward. Place the PTFE sleeve end out of the way.
#Cool to below 85 F/30 C.
#Turn off the TAZ 4.
#Disconnect the extruder assembly electrical cords, by detaching the Budaschnozzle cable (four wires: two orange, two red), the extruder stepper motor (four wires: black, green, white/blue, red), and fan (two wires: black and red).
#Remove the extruder from the Y-axis assembly, by loosening and removing the retaining bolt (using a 2.5mm Allen wrench from the TAZ Toolkit), and sliding the assembly up. Put the retaining bolt and washer in a part dish for later use.
#On a separate table, remove the fan (using a 2.5mm Allen wrench from the TAZ Toolkit) to facilitate the next steps. Place the two screws and washers in the part dish, along with the fan.
#Remove the larger bolts (using a 3mm Allen wrench from the TAZ Toolkit), placing them in parts dish.
#Remove filament stepper motor/gear assembly.
#Remove Budaschnozzle.

==Replacement==

#Ensure that the wiring for the Budaschnozzle is not wrapped around the assembly. Arrange it to go up vertically.
#Place the Budaschnozzle on the extruder assembly back plate, ensuring that the Budaschnozzle wire is facing you and not caught between the Budaschnozzle and the assembly back plate.
#Place the 2 large bolts in place from underneath the extruder assembly back plate. Hold those in place with one hand, and with the other hand, place the filament motor/gear assembly, aligning the holes with the bolts. You may have to jiggle the filament motor/gear assembly to get the bolts to line up, initially or during tightening.
#Carefully tighten the bolts using the 3mm Allen wrench; be careful to start the bolt in the thread of the nut with gentle pressure, as it is possible to push too hard, causing the nut to fall out of the filament motor/gear assembly.
#Affix the fan to the filament motor/gear assembly using 2 small bolts and washers, tightening with the 2.5mm Allen wrench.
#Attach the completed extruder assembly to the Y-axis assembly by sliding the wide-V shaped bottom of the extruder assembly into the similarly-shaped receiving slot, ensuring it is seated all the way down (apply gentle pressure). Insert the remaining bolt and tighten using 2.5mm Allen wrench. (Suggestion: first put the bolt in the extruder assembly, holding in place with the Allen wrench, and then seat the extruder assembly into the receiving slot; then tighten the bolt.)
#Re-attach electronic connections, ensuring proper orientation and mating of connectors:
#*The Budaschnozzle cable (four wires: two orange, two red)
#*The extruder stepper motor (four wires: black, green, white/blue, red)
#*The fan (two wires: black and red).
#Reload filament by inserting filament through the top of the extruder assembly and pushing down as far as possible; approximately 3 inches/75mm of filament can be pushed in after initial entry into the aluminum plate of the Budaschnozzle before the filament end “hits bottom” at the actual nozzle. (Note: if a bulb of filament makes this difficult, snip off some filament with scissors at the point where the filament is the proper diameter.)
#Re-latch the idler assembly by raising the screw assembly, pushing the idler plate flush with the filament and hobbed bolt assembly, then slipping the screw assembly down over the idler plate. (Note: it might be necessary to loosen the screw assembly, but then re-tighten.)

3D Printing

Rayharwood: Added link to Procedure Documents

See [[TAZ 4 Procedure Documents]] for help with things like removing and replacing the Budaschnozzle.

==Lulzbot TAZ 4 Printer==

I bought the [http://www.amazon.com/LulzBot-TAZ-4-3D-Printer/dp/B00JXQZ8CC Lulzbot TAZ 4 from Amazon/Prime]... only $2,194.95, free shipping.

The manuals are included, but you will need to read carefully, and also research some on the web. Calibration of the Z-axis is critical to successful printing, and this process is not really well presented for the brand-new user. (I'm sure any teenager can figure it out themselves; a 60 year old like myself - as technical as I am - had to do some research.)

==Filament from Shaxon at Fry's Electronics==

I went online to the Lulzbot site to order filament - don't bother. Seems like most of their filament gets shipped from the UK, so my initial order for about $100 worth of filament was going to cost over $100 extra in shipping charges!

Instead, I wandered into the Phoenix Fry's Electronics, and they had a reasonable supply of filament from a company called Shaxon. I bought three rolls of 3mm filament in 1 kg/2.2 lb reels for $24.99 each: PLA White, PLA Blue, and ABS Yellow.

==Modeling Software: FreeCAD==

I had initially tried using [http://www.blender.org/ Blender] for my 3D modeling; in fact, I used it to create my first 3D print of a beveled 10mm cube. But I quickly found that Blender is best suited for animation modeling, and while it will model some things and output the required STL file, it really wasn't conducive to what I needed to do.

I also tried Adobe's free [http://www.123dapp.com/ 123D Design] program. While the program itself really seemed to have potential, the whole online login and cloud storage experience was extremely frustrating, so I eventually gave up on Adobe.

Currently, I'm using [http://www.freecadweb.org/ FreeCAD]... I guess "learning" is more accurate. FreeCAD seems to have what I need, and so far in the learning process (1 day, as I write this!), it really looks more suitable, and has a more professionally done feel (in my opinion).

Write to Netduino SD card

2014-03-21T14:02:16Z

Rayharwood:

Note that many examples online indicate a simple file name "Test.txt"; I've found that only the full path works "\SD\Test.txt".

I'm using the Netguino Plus 2, which has an onboard SD card slot. You do not need to "mount" the onboard SD card, per [http://forums.netduino.com/index.php?/topic/4349-onboard-microsd/].

'''You must use only an SD card, not an SDHC card; and a size limit of 2GB.'''

== Netduino ==
Now my primary micro development environment: using Visual Studio 2013, .Net Micro Framework (NETMF) 4.2 (4.3 is out in beta), and I'm programming in Visual Basic (most examples are using C#).

For ease of ordering, please go to my [http://astore.amazon.com/rayhar01-20?node=4 Amazon store].

Code examples include:
* [[Write to Netduino SD card]]

== Arduino ==
Has it's own development environment; very good for learning, but (in my opinion and experience) limited if you want to do extended device control.

== Gadgeteer ==
Another NETMF-based open-source board.

== BeagleBoard ==
Windows Embedded Compact runs on this board.
