Re: Embedded Camera

Not sure how to implement it, but I've seen cheap laser pointers (with x-hair pattern) used with a camera for not only automated homing but also range finding to get a touch-less Z offset. Perhaps the Processing + cheap/good CCD camera + laser pointer combo often used to make 3d scanners has been or...

Re: Anyone tried EMC2Arduino

Neil and I have been talking about some interesting ways to clean up and improve some things for the next release.

To Me, it sounds like He's got some great ideas and like you I'm pretty eager to see what he has in mind.

Looks like you need to make a user account in order to be added to the admin list. Its free though.

Re: Anyone tried EMC2Arduino

Oh, found that cds.ngc file I mentioned earlier. You should be able to find it at ~/linuxcnc/nc_files/examples/cds.ngc You'll need to use the "Touch Off" buttons to touch the offsets. Home the machine, select the X click Touch Off, enter 2 inches then repeat for Y and enter 3 (I think) for Z then it...

Re: Anyone tried EMC2Arduino

I think that would be awesome, I could DEFINITELY use the help! If you would like or if it would make code dissemination easier I could give you a fork on github. A place you can collaborate/merge code from the work several people into one place. I think EMC2Arduino could stand to offer a 3-axis cen...

Re: Anyone tried EMC2Arduino

I'm glad to here that you have full movement and that expanding the timing options helps get you there. powerConservation vs control: If you'd like to control the drivers though Axis (via +P/-P) then you'll need to set conservePower to false. Otherwise its only called from near the bottom of the loo...

Re: Anyone tried EMC2Arduino

Hehe, I think I might have beaten you to it.... Attached is an alpha release featuring some of your suggestions: Power conservation, drivers sleep when the machine idles for more than 2 seconds. Configurable enable/disable drives at boot. Individual step state variable per axis. Individual step rate...

Re: Anyone tried EMC2Arduino

I think I know whats going on with your Z axis. The step rate frequency is too high for it to move (in full steps). The Arduino code needs to be modified to allow individual step rates on a per axis basis. Power problems: There's a easy software solution to your powerup sequence. If you can slave th...

Re: Anyone tried EMC2Arduino

Here's a modified set of files to help get your ShapeOko up and running like a champ. Please review them before use... Included: Tweaked Emc2Arduino 0.07b firmware. So you can review min/max/home settings that match up to the my-mill.ini file. my-mill.ini 3-axis config with looser latency settings, ...
