Problems with Mach 3 , new user.
« on: October 17, 2018, 11:57:25 AM »
Yes, new to Mach 3,  Finished up assembling a CNC Router Parts CNC.  Had a Next Wave CNC before.   
Issues:
With a program from Aspire, The X & Y zero is at the far right end of the table. (Spindle facing me) On the Next Wave machine, it was at the forward left end of the table.   If this is normal, then I must live with that  Is this normal??

When running the G-code in "off Line" mode, the Mach 3 runs the lines of code step by step without missing any steps.  But if I run the G-Code with the spindle running, it misses 100-150 lines of G-code.
That is not normal.

I'm running CNC Router Parts "In." Post Processor. Do not know if that is correct.  Should I run a Mach 3 Post Processor??

 With VCarve Pro and I am sure Aspire is the same you set the Origin anywhere you want. I use Center of the work for mine.  Yes you need to use the Mach3Arc Inch  Post Processor.  Are you using the CNCRouter parts setup file for Mach3?
Sounds like you need to do some CNC101 research on your machine and Aspire.
Normal Zero on the two Mach3 machines I have used has been forward, left corner.   If your missing steps then the setup for the motors is not correct.

The CNC Router Parts post processor is basically the same as the Mach3 post, with an M7 to start a dust collector.

If you are referring to the home switch position, then it doesn't really matter. The "Home" position is in machine coordinates. When you cut parts you use work coordinates, and set the XY zero for the work coordinates wherever you want them to be.

What do you mean by "missing g-code"? Is the machine stalling?

Thanks for all the advice...  Found out that the Machine "Zero" was not set up & when the program started, it went to a location I did not want.  Now I have the Machine "zero" fixed & no offsets.  Still a learning curve here with Mach 3.

Am not getting "missed steps" of g-code like before....  but will do more programs to get more confidence in running the Mach 3 & make sure it does what I program.
