Re: Extruders

I think some of the mods since my 'Oko from the original Kickstarter may have helped, like the dual beam on the gantry. The trouble is that 3d printing speeds tend to be higher compared to milling - each layer is 0.2mm or so tall, and the width is only slightly larger than that on each pass. You can...

Re: Extruders

Looks a lot like the Qu-Bd design with a spring upgrade. Without handling it I can't really say if they've fixed the issues that plagued the Qu-Bd design, but at 45 euros, I doubt it. The extruder & hot end are the core of a 3d printer, and going cheap doesn't pay off in the end. I learned that the ...

Re: Upgrade Parts!

It might depend on the grade of aluminum & how much force you need (how heavy the tool end is, how deep of a pass you plan to make, etc.), but on the end plates, I can't see anything more than 1/4" being necessary. But that's me and the scraps of aluminum I've got lying around. I just got a drill pr...

Re: Seeking advice on a simple inexpensive 3d printer "spind

The Shapeoko frame itself isn't quite perfect for a high-res 3d printer. In particular, the Z-axis Makerslide is weighted on the top & bottom by the motor & extruder. Unless you've done a truly amazing job stabilizing or just run slowly, this will bounce a little bit during sharp Y movement. Usually...

Re: how to modify GRBL for Z axis to tool ON OFF

I wrote a script that makes a few modifications for laser-friendliness: http://qcgeek.com/laseroko/ *turns laser on at every g1/g2/g3 *turns laser off at every g0 *removes all Z movement *removes all F speed changes Typically I use Inkscape to draw the shape, the Inkscape GCode plugin to generate th...

Re: Mark II

My main concern with mounting the electronics in the machine is that it'll be harder to defeat when the machines rise against humanity! I really like the idea of being self-contained & less spaghetti coming from the machine. I'm also a big fan of the dual steppers vs. the drive shaft. Yes, it might ...

Re: Mark II

Now that I think about it, there are a lot of ways I could make a quick change plate for my needs, and those needs don't match those of most users. I'll take it off the list, and add the following: Limit switches - 6 small switches plus wire & mounting hardware should be less than $10, increase repe...

Mark II

WillAdams posted his thoughts on the potential design for a Shapeoko Mark II in another thread and in the Wiki ( http://www.shapeoko.com/wiki/index.php/Mark_II ). It got me thinking about what my wish list would include. This isn't necessarily saying that these are practical designs, but still on my...

Re: Upgrade Parts!

WillAdams, thinking about what the official "Mark II" would/should include is intriguing. I'm going to break that off to its own thread under design.
