General Mach Discussion / Scale button in mill

« on: August 26, 2015, 05:21:24 AM »

Hello!
I've used mach 3 lathe for quite a while and it works great for me.
I just bought a 4 axis mill and I'm trying to do some engraving on brass rods telling the machine the A axis is the Y axis.
I then use the text engraving wizard to create the paths.
In order to keep the letter dimensions correct I need to down scale the A (Y) axis to a value that depends on the rod's diameter.
So far so good, I did my math and I know how much I need to down scale it.
Problem is that when I click on the scale button it blinks but when I start machining it goes back to 1.000 (no scaling).
For now I did a workaround, I changed  the motor pulse number to make a mechanical scaling but the software one would be much better.
Ideas? Why does it revert to 1.000?

I think you misunderstood me: I know how to set up backlash and the making of all the fields regarding it in mach 3.
Simply it doesn't enable it when I flag the check box. No value in the motor tuning window, no % in the speed for it, no amount of compensation and no time to do it in General config make any difference.
It looks like the enable button doesn't work.

I have the same issue: on one computer I use for a lathe backlash didn't work for months then, for no reason, it started compensating.
The new lathe with a German version of Mach3 works ok.
Today I tried the old computer with a new 4 axis mill and backlash doesn't work...
How come??
