Title: % axis movement in MACH4
Post by: chuck767 on December 10, 2019, 12:25:28 PM

In MACH 3, a part could be built smaller or larger than the designed part by changing the percentage of the axis movement.

How is this done in MACH 4? 

ie, in MACH 3, a part could be built half size by changing X, Y, and Z  to 50%

Thanks,
Chuck

Hi,
that feature is a property of Gcode programming, any good CNC software solution will do it including Mach3 AND Mach4.

It called G51 scaling. Page 42 of the Mach4 Mill Gcode Programming manual in the Help Docs folder.

Thanks Craig,

I was hoping MACH4  had the same % features as MACH 3.

I have a small tabletop mill at the house, 12 inch X travel. I use that mill to test programs I run on my larger mill and laser just to make sure everything is working right. It's very convenient to simply change the percentage MACH3 and use the exact same G code on the larger machines run at 100%

it does. Code g51 in MDI panel and your done. If you want to attach it to a button or a slider you can do that too...

Thanks Craig, I was not aware of G51
