=== Before you can start milling ===

Using the CNC is not as straight forward as using the [[Lazzzor]]. From the handling, it can be compared

with a [[3D-Printer]] but there are still more steps involved.

To work with the CNC machine you need the following things ready:

* G-Code

* Cutters suiteable for your material

* Material

* A method to fixate the material in the machine

* A method to measure workpiece coordinates and save them in LinuxCNC

While the Material and Cutters are usually not the biggest problem (see [[CNC]] and [[Benutzer:Fbr/WhereToGet]] for more information), G-Code generation

is probably the hardest part. Also fixating the material can be challaging, as well as measuring the workpiece coordinates.

The easiest way to get G-Code is using CAM software. Such a software can "convert" CAD parts into G-Code. There are some OpenSource projects

but most of them are not really powerful and only work for simple pieces. See also [[CNC#CAM]] for a list of Tools.

Expensive CAD software has also powerful CAM modules, but they are in the range of 10k€ or more.

Fiaxting plates and rectangular workpieces isn't a problem, as we have a set of clamping claws and a T-slot table. For other pieces it might be a good idea

to build a fixature first.

Measuring the workpiece isn't too hard either, if working with non-complex geometries.

Ask for help, if you need to clamp or measure an complex part! There is always some trick you can use.

There are some important steps to take, otherwise you can destroy everything - even the earth...

If you don't switch on the things in this particular order it can happen that the machine does things out of nowhere e.g. moves or turns on the spindle!!!

~~=== Start Up ===~~

# Start CNC PC (do not turn on the G4 (The "G4 Case" stepper control thing), neither the VFD)

# Start LinuxCNC, make sure the X-Box controller is plugged in, otherwise starting the LinuxCNC doesn't work
