[Emc-users] TRAM Write Error

All, I am getting a "TRAM write error", and not finding much on it in a search. I am running lcnc 2.8.0-pre1, and using the Mesa 7i43 board. The error occurs when I physically assert the enable for the third axis. The first two axes came up fine, but if the only change I make to the

Re: [Emc-users] LinuxCNC

The robot in the videos most defiantly NOT something you would want to use LinuxCNC for.They do real-time path planning. Today I'm implement that with something like a self driving fork lift and save the cost of all that track. The machine would roll on the floor with wheels and if it was

Re: [Emc-users] LinuxCNC

Several years ago I worked on a quote for a job of similar size but the accuracy had to be much better.   I think it had to be plus or minus 0.010 inches or so over the entire 3D space. A 3D laser tracker was part of the control scheme to track the actual tool head location. That way standard

Re: [Emc-users] LinuxCNC

Hmmm, interesting but there's guys already working on that. No, different application but with some similarities - placing a calculated amount of a fluid at a specific point or range of points in a 3D space. > On Aug 22, 2017, at 5:02 PM, Gene Heskett wrote: > >> On

Re: [Emc-users] LinuxCNC

That's why I wonder about rolling my own versus starting with something like that in the video linked below. Not sure which would be harder, more expensive. https://youtu.be/NRO98Rm58-k > On Aug 22, 2017, at 4:30 PM, Chris Albertson > wrote: > > The resolution

Re: [Emc-users] LinuxCNC

The resolution is controlled by the step size of the motor. It's mechanical. Getting to 1/8 inch over a 100 foot space is easy in terms of the software but you will need to invent some hardware that holds to those tolerances. On Tue, Aug 22, 2017 at 3:35 PM, Rick Gresham

Re: [Emc-users] LinuxCNC

I've only just started trying to learn a little about realtime motion control so I don't have a good answer re: units. While a complete Star Trek-like plant console might be really cool, I suspect the investment would be hard to justify for a largely lights out application. I don't need the

I'm exploring options for a 3 axis controller similar in some ways to typical cnc router-like application. What may make my application unique is the size of the 3D space in which the tool operates: up to about 150' x 150' x 50'. In addition, I need to control tool changes and

Re: [Emc-users] MDI edit/UI question

I've ran into this problem, too; best as I could see, it wasn't possible to use the keys with that particular entry box, so I made a few modifications to the axis.py script to give me left + right, home and end keys. It seems to have worked fine for me, for > 6 months. Philip >From
