Is this for lathe or? What's the use case?

So you want it to over-cut in slots where the tool won't fit?

Actually, this got me thinking a bit, the table is hard to yank around and
get real results. But we can actually measure the spring in the system, if
we have something rigid enough to push against. Stick a spring of known

I'll try to change for myself convert_straight(),
convert_straight_comp1() , convert_straight_comp2()
Maybe someone similar already did ?

the new encoder seems to work good :)

There's about .0015-.002" of backlash and an .0005" spring in the system
at reasonably force levels at the highest points of stiction on the ways.
I'm sure I could get more spring out of the system if I run an endmill
into the vise, but we're not really testing that here.
Ballscrews, precis
No-one has mentioned the mechanics of the system.. (or have they?)
What is the mechanical coupling like between the stepper and the linear
scale. Obviously it's most susceptible to backlash and belt stretch.
If the stepper is holding fast, how much linear deviation can you get if
you try move the
Not that I know much about this but: It is my understanding that the
rotary because it has less quantatization error does a better job on
control but unless your machine is very tight a poorer job on position.
Early on I tried my machine with a 5 um linear glass scale. It was very
difficult to

The rotary loop works fine by itself.
