Re: [Emc-users] BeagleBone and LinuxCNC for a lathe.
So I've done a little more investigation all without spending any money yet. The Probotix web site links to the wiki which points to the MachineKit LinuxCNC for the BBB. I downloaded the 8GB image and installed it on a MicroSD card. Stuck it in a Rev B (2GB FLASH) BBB and booted. It shows up as 192.168.0.124 on my network and after a few hours struggling to get Xming working I now have the following up and running. http://www.autoartisans.com/cnc/PBX_BB_Xming.jpg Clearly it's been configured for the Probotix BB Cape. And there's no input set up for a spindle sensor. This is really a Mill or Rapid Prototyper configuration. The previous MachineKit I installed wasn't that much different. Forgetting for the moment a controllable speed spindle and just going for a single pulse per rev spindle sensor where would I begin to set up this system to run a lathe? I have to use X and Z for the cross slide and lead screw respectively. That leaves the pins for Y and A. There are limit inputs for ESTOP, XYZ A for limits. I almost wonder if there should be a book called Beagle Board MachineKit Linux CNC for Dummies with Windows 7.

Re: [Emc-users] BeagleBone and LinuxCNC for a lathe.
I did exactly that with a BBB and Xylotex cape, using one of the unused limit inputs for a single pulse per rev sensor. You might want to follow the discussion on https://groups.google.com/forum/#!topic/machinekit/RW_bnXdXzyE (you'll have to read up to the end). You need a little familiarity with redirecting the input pins of the BBB to the hardware encoder (eqep) on the BBB processor, and in case of the Xylotex cape, I had to remove the large capacitor of the input RC-circuit because it smears out the pulses too much. The eqep encoders are fully supported in the present machinekit images for BBB. I did successfully manage to do threading on a small lathe with that contraption.

Re: [Emc-users] 2.7's new Trajectory planner.
Thanks Robert, and thanks Sam et al for testing I'll be moving soon and hope to get re-setup and try some of this TomP tjtr33 On 08/13/2015 07:54 AM, sam sokolik wrote: As 2.7 gets closer to release I wanted to make some comments on where the new TP is at.

[Emc-users] 2.7's new Trajectory planner.
As 2.7 gets closer to release I wanted to make some comments on where the new TP is at. I have been running it through its paces as others have. Thanks to all that have posted gcode that caused issues. Rob has been a genius at fixing issues as they come up. A huge thanks to Rob and Tormach for coming up with a great solution! At this point I think the TP is pretty darn good. I have a few programs that give a slight 1% overage in acceleration. Rob hopes to get to it when he has some time. The current TP actually has worse overages in some situations. (see screen shot - worse is relative as no one ever notice it that we know of) Notice that the new TP ran the Gcode almost twice as fast... current TP http://i.imgur.com/hl14TlT.png 2.7 TP http://i.imgur.com/OwyvuM1.png Thanks again everyone that has tested 2.7. It is going to be a great release! (also - test if you can - we always need more testers) sam PS there are things that rob has demo'ed too - like reverse run.

Re: [Emc-users] 2.7's new Trajectory planner.
I've been running 2.7 for a while on my plasma and the difference it unreal. 2.6 would choke on letters generated with nurbs but 2.7 just runs at the speed I tell it to for some beautiful cuts.
