Re: Stepper motors

The kits from inventables will include the correct M3 fasteners to connect the standard nema17 motors. If you're going to use nema23 motors then yes, you'll have to get the M5 bolts to mount those motors. If I recall correctly, M5 x 16mm socket head cap screws will work great. When you mount the mot...

Buildlog Stepper Shields

Hi All, I have a couple of the newer buildlog stepper shields for sale. It's just the boards, not the components. These are the boards that support dual Y drives. They are $12 each, which includes shipping domestically. If you're out of the States, we'll figure out what postage will be and you can p...

Re: cable lengths question

Specifically for the Shapeoko, your wirelength should be enough to get from the furthest point in the X axis, with the z at it's maximum height, back to the Y motor mount, and then back to clear the rear plate. The total length of that would be roughly 900mm for the X and Z motors. For the Y motor y...

Re: Useful Links!

That won't work as an endmill. From what I can see it's a standard drilling bit, not meant for side cutting. There's always a lot of talk regarding if one should use an end mill to "drill", and I think purists would tell you that an end mill is for milling and a drill is for drilling. However, there...

Re: Spindle Alternative for 230V

@jb77 Thanks for bringing it up again.

The mounts will be like the one's shown in the renders on the inventables page. They're a plastic (UHMW or Delrin or HDPE, yet to be decided) and have proven to work very well.

Re: Spindle Alternative for 230V

That Silverline spindle is exactly the spindle that I use on my machine and the one I sent out with the kickstarter kits (obviously mine is the 120v version). I'm not sure what the true name of it is, but you'll find it rebranded all over the place under different names/colors. Mine has been in use ...

Re: Grbl on Arduino Mega

I know the 3D printer people use parts of grbl in the Sprinter/Marlin firmware and those run on the Mega, so you're probably right, only light modifications, although Alden would be much better at addressing that. Frankly, I'm not interested in porting it to Mega. What I am interested in doing is ex...

Re: cable lengths question

We started talking about a wire management system (shapeoko created of course!) over on the old google group. Prior to the current proposed linkage setup I was suggesting a simple flexible wire be used to support the cables. In fact, my original setup consisted of 1 wire (a piece of sprung steel fro...
