hubs

[Lynn Demers]

will there ever be an option to add hubs to a gear for fastening to a shaft with set screws or what ever. with that you could print a gear from beginning to end with no other modificat ion.

Hi Lynn:

   Up to now I havent worried about hubs as the vast majority arent using 3d printers, but I can see I may have to consider that in the next cycle,
the use of 3d printing appears to be growing very fast. I WILL take this one under advisemen t. Some day I may get my own 3d printer working,
I guess Ill be forced to at that point anyway..

When you get to hubs you might give some thought to flanges.   They'd be handy for timing gears and other belt drives.

After a 7 month wait my 3D printer (Printrbot+) kit just arrived, with luck work will let me start on it in a couple days.  Hope to be printing GM designed gears (not to mention other stuff) with it real soon now.

Some day I may get my own 3d printer working

Maybe you could start with a reprap like a MendelMax to get some experienc e/have some fun, then continue with your own design.  I don't recommend Kickstart er for a first printer unless you're willing to wait way more than you expected

 
Looking forwards to another Season of Amazing Things for GM.

   I may pick up 3d printer later this year for testing depositio n ( or likely just add a depositio n head to my router )
for testing stl outputs. My personal build printer is really more of a sucession of experimen ts and god only knows
if it will ever really do 3d printing. .but I enjoy the experimen ts so much that end result doesnt matter much to me in
that area. This week I got my UV laser to do scanning of an image..pr etty cool looking I must say. I hope to show you
that in a video in a month or two as I build a rig to automate the scanning head.

   Flanges are another thing I really hadnt considere d because of course again their only pertinent in 3d printers.
But I think its getting obvious to everyone that 3d printing is becoming very popular, so I will add that to my list as well.

 If you decide to add the FDM extruder to your router you may want to look at the article that I just had published in this months issue of Digital machinist . It was the feature article and made the cover of the magazine.
The article basically shows how I added and extruder and and external dual thermosta tic controlle r to one of my many machines.
Art , they sent me several extra copies of the magazine. If you want  I can mail you one. .
I'm using with Mach3 and a program called slicr. It's pretty good and free.  As I recall I have my xml file set for 900mm velocity but have run it as high as 1200mm

    Thanks, that issue shoudl show up at my specialty bookstore anytime now, Ill get a copy.
It'll save me time instead of having to figure it out. 1200 is pretty high, Im impressed .

  Im familiar with slicr, though I havent used it as yet.

Thanks
