I like free open source software too. In fact I finally switched from Eagle to Kicad for schematics and PCB design, IN the past Eagle worked and Kicad as a development process. Kicad caught up because CERN (the physics lab in Europe) adopted and funded Kicad. But open source CAD/CAM is just

I think using a screen only works on small size printers. Bigger screens lack resolution.The phones and tablets have about 300 pixels per inch. Look at monitors. The new "standard" is 4K. If it is 20" across that is 4000/20 pixels per inch or 200 pixels per inch. Not as good as an

Autodesk Fusion is 3D CAD software for making 3D designs. It will also "slice" those models and output the g-code that will drive a 3D printer layer by layer. Fusion can also produce g-codes for driving a mill or lathe. That is one of Fusion's best features: It is an end-to-end system

Re: [Emc-users] new thread inspired by Christophers question about 3d printer sliceing SW.

You could do this on a mill but how fast is your mill's jog speed? Mils are typically slow but very accurate. Buying a heated pad for your mill would be easy, just buy the part in any size you like. It need not be as large as the mill's table. Mounting the head could be as easy as placing it in

Re: [Emc-users] new thread inspired by Christophers question about 3d printer sliceing SW.

You can print without a heated bed and you can just slice a stl file and remove all the M codes and run it on your mill and watch the velocity, if it is constant I'd say you can print. JT On 5/16/2017 8:27 AM, Gene Heskett wrote: > Greetings all; > > And the next logical question from me is:
