If you've ever seen a magnesium engine or transmission case
burn, it is quite a show.
And, when the fire department doesn't have foam in their

There are ways to make magnesium very hard to burn. NeXT did it to the cases on
their computers. https://simson.net/ref/1993/cubefire.html
I assume that laptop computers with magnesium cases use similar alloys.
Mongoose BMX bicycles back in the 80's did a sneaky thing for their factory
team.
Have you considered external offsets for this? I have had moderate success
turning low lift cams with this feature.
I'm preparing the retrofit of a cylindrical grinder with LinuxCNC to
achieve camshaft and crankshaft grinding. With external offsets you don't
need a really precise servo spindle. A
I'm getting to the point where I need my own camshaft grinder.
The question I have is the G-code. The grinder has 2 basic components, a
rotary operation to turn the cam and a linear movement to move the grinding
head. For simplistic sake, say the G-code is 360 deg with the corresponding X

When you say "nothing" do you really mean "a major upgrade from
LinuxCNC 2.7 to LinuxCNC 2.9?"

So, cursor keys?
There have been some changes to incremental jogging, but I don't know
