Hi,
I’m very new to CNC machines and G-Code programming, I need some advise.
I have completed my first CNC machine. I’m using Mach3 with Xylotex 3-axis driver.
I’m trying to figure out coordinate systems so that I can create/use g-code programs to make parts and stuff (use my machine).
I’m confused about g-code programs and machine calibration in general.
QUESTION #1.
Is it required and normal to always calibrate the machine to the specific g-code program?
For example, I’m having trouble running the Roadrunner program; my machine is always going out of bounds. And I don’t know how to home my machine to the correct starting point so the program will run correctly.
Or is there a general calabration process that will solve all these problems ?
If so, where can I find a clear tutorial on how to do this ?
QUESTION #2
I have limit switches, it looks like some of the X-3.8999 stuff is always going to trigger my limit switches. What do I do. I’m confused.
I have reviewed the setup on my mach3 software, but I’m confused as to the general nature of what is going to be required to calibrate my machine, or as to why I can’t run the roadrunner program (and other programs correctly).
Thanks for helping.
