Title: Mach3 scaling issue
Post by: Sullie on February 18, 2020, 04:15:47 PM

I currently have 2 CNC tables that both run the same program of Mach3, I just started my new CNC but for some reason the g-code loads perfectly normal and lays out on the screen to scale, but when I start the program on the new machine it follows the correct tool path but at a much smaller scale than the DXF drawing I imported into it to create the g-code. The same exact g-code runs fine on my slightly older machine, but the same exact g-code will not run properly to scale on the new CNC. What would cause this to happen? and how can I fix this issue? The file extension is an .NC and I am pretty sure I ran into this problem before but cannot remember what I did to correct it, I think it had something to do with the file extension.

maybe metric / imperial Units?

Config -> Select native units

When using manual movement commands, do the axis move the same amount and correct distance when comparing the two machines?
