I keep reading that I need to $ . scripts/emc-environment
I have tried typing this into a terminal and it gives an error. I have

Where exactly do I need to be?

Hi,
Use an axis to control your turret.
As far as losing steps to guarantee that it's "locked" goes, all that is
necessary is a g93 to tell EMC that now we know where the axis is based
on the tool position.
G93 changes the coordinates without movement.
For example if my Z is a little sh

Hi All,
I occurred to me that all you need to do is poll your positions once a
second and then construct a G01 from that.
For the feed rate use G93 F60, inverse time, so it completes the move
in one sixtieth of a second.
I think a one second position update interval will work fine for

Where are the modules?
Where do I put them? (In my Hal file, ini file?)

One other thought. If your drives are in that plywood box with the
smoked plexiglass cover they could be overheating.
I had a test rig that was on plywood and it would act weird because it
was overheating. All the problems went away when I installed it in a

If you are using feed override at any percentage, it can sometimes
affect your rapids, it. the rapid speed is also overridden, exceeding
the machine's capabilities.

In your control box, your step and direction have to be kept well away
from all your drive power and motor cables.
