As the topic says, I am totaly new to this. Linux as an os, CNC operating at all and LinuxCNC as a software to drive my machines.
For now I am concentrating on my Emco Compact 5PC lathe (I also have a mill but that has yet to be conquered).
After a bit of fiddling, I got the 5PC to listen to emc2 commands, using the configuration that Sam made for his. Machine is using genuine steppers and electronics.
I have no limit/home switches set, and its most likley to stay that way in the future.
Now, I am here at baby steps. What is the next step I should do?
I ve spent hours reading, but I am pretty much clueless what to do next?
Tooltable would be a logic thing to do? From what I could find and read about, I didnt get what is that I am supposed to do.
So could you help me out here , step by step, like explaining everything to some empty brainer

All the parts that I intend to produce are drawn/modeled in Solidworks, but we will get to that point of generating g code and making it usable in production.
Thank to all of you in advance, for the help I am sure I will get here

Does your lathe have a tool turret?

Limits and homes are rather useful, it means that the machine knows where it is.I have no limit/home switches set, and its most likley to stay that way in the future.
I don't know if there is much point having a tooltable if you have no repeatable homing. You might as well just touch-off G54 every time you change tools.Tooltable would be a logic thing to do?
Have you run any G-code yet? Try running the lathe_pawn.ngc file in the sample nc_files directory. Initially with no tool and no stock, but you can make the actual part if you want, it needs 25mm stock and assumes that it is faced-off to Z=0 and the end of the stock and that Z=-32mm doesn't hit the chuck.
Don't make the mistake I did, of touching-off in radius mode to a diameter measurement. (Live and on video )

Homing and stop switches are good thing I know, I might add them in the near future.
I tried cutting air for bishop, and then made the actual part from acetal (tried to make a video too but something wasnt cooperating in that process

As for interface, I use axis.
After tool setup, I should move on to getting usefull gcode from the parts drawings...

Well, I intend to use several tools for one job, so I guess i do need a tool table set?
Yes, if you have a suitably repeatable toolpost,
One way to work is to have a "master" tool that you make sure always has zero offsets everywhere. You can then take a test-cut with that and use the "touch-off" button to set the coordinate system.
You can then make a cut with another tool and measure the work, then touch-off again, this time into the Tool-Table.
This way the offsets of each tool are differences from the Master tool. And when you start a new job everything should work once you have touched off the coordinate system with the master tool.

Also, any suggestions on easy to use cad cam programs? Basicly, I will be making simple ball shapes, and threads, on a previosly prepeed stock.

Got it on master tool and following. Just to figure out how
"Touch-off" is a button in the Axis GUI.

Plus no one that I know personally that is operating machinery is using this software, and that makes thing even harder.
Thank you gents for your effort, but I have to pull the plug on this.
