3d-modeling and g-code generating for beginners
« on: November 18, 2020, 03:55:42 AM »
HI guys.

I have finnaly copleted buliding my own 3axis cnc mascine.
I have it upp and runing. Now i have a problem (no really :-) )
Althoug i know how to do 3D models i have really hard time with finding a basic enough program that would exlain and allow me to actually get a g-code out from it.
I am hoping if anyone of you can suggest me some basic program that has good tutorial on how to tell program to do what i want and get g-code out.

Thanks.

If your 3D modelling package will output an .stl file then MeshCam may be a good choice for creating a Gcode file for your CNC.   https://www.grzsoftware.com/

Hey guys
I am now learning with few CAM programs to see which one i like more but the problem i am faced with is the Z,Y,X axis.not one program has same axis setup.
And the resoults in g code i get out are all wrong.
Do i have to rework my mascine so that axis will be same or is there any way for me to set them up in Mach.
And also do axis in model have to match axis of mascine? cuz i cant figure out how to change them in program....

Your machine axis should be set-up according to the 'Right Hand Rule' which is detailed here; https://www.machsupport.com/forum/index.php?topic=10308.0

Ok i have setted it the way it should be.
Why the wizard programs in the mach3 have insted of Y axis set Z axis??? Also the CAM programs have set that way too...
What is that with Right hand walue if programs are set diferently?
