QCAD 3.2 now with CAM addon

I did not had time to play with the new version of QCAD 3.2 (free and open source) yet, but I did notice it includes a CAM add on (not free, but 15 min trial mode with restart possible). http://www.qcad.org/en/qcad-downloads-trial Did anybody try the CAM module yet? On the CAD it self it looks like ...

New natural CAD system that uses VR

Hello, have a look at the page and video: http://sixense.com/makevr . To me this looks like it would be a very good system for beginners and I think it would be nice to use my hand more naturally. Working with a 2D device (mouse) in a 3D space is not that efficient. I don't have a Razer Hydra yet, b...

Re: molex connectors & alternatives?

I found a $20 crimp tool at my local electronic store that works ok. I found soldering was not very helpful, and caused damage inserting the pins sometimes... it took me a while to master crimping the pins. I found that if crimping to much it would not longer lock in place (micro fit style).

Re: Free 3D (STL) G-code generator?

I would guess HeeksCNC is the most powerful FOSS for CAM that exists today. I think the FreeCAD people are working on a CAM module but this is still in it;s infancy. If you come from 3d printing you probably know Skeinforge, by looking through all the settings tabs it looks to me it also supports mi...

As most Shapeoko folks have the 4 wire steppers I guess not many would need this board.

Re: Seeeduino v3 does not work with grbl 8c

I think it works without G0 or G1 because the mode is modal and you don't need to type it all the time... anyway the issue sound like the direction on the Arduino is not connected to the direction pin on the stepper driver. Looks like this one bit is not toggling. The big question is now is this a h...

Re: Seeeduino v3 does not work with grbl 8c

After the upgrade did you set all you parameters again? You may also want to ask this question at the developer github page.

Re: The Rules of Shapeoko

I did the Home Depot, Loews or Ace runs too, three weeks ago I found a commercial bolt store and now my rule is to only buy in boxes of 100 (as suggested on the forum).

I think I paid around $2 for 100 M5 washers...

Re: 4 Axis mod ?

Does anyone have a good link for a simple and cheap stepper motor driver ( Nema 17, the same as used on the Shapeoko) ? I got me some of these on Black Friday, I just connected it to a breadboard yesterday and used an Arduino to and some pules to drive it... there is a little cheaper low current ve...

Re: Easy Hold Down Table

I have a ShapeOko (2 Y stepper both with outside belt) with 20x20cm cutting area. I never cut a thing yet, but I'm planing to do that soon. Because I don't have any experiences in this regards I was wondering what would be a good grid spacing for the holes. I was thinking 5 cm (2 inch) would be good...
