perfectly.

Greetings all;
I now have a nominally 180 degree cam on the BS-1 home switch.

The trajectory planner obeys the MAX_ACCELERATION, the problem is when you
throw backlash compensation in on top of it. The Step generator then needs the
extra headroom in STEPGEN _MAXACCEL to catch up with where the trajectory
planner is commanding it to be plus the backlash take up move. So

That little green machine of yours really hauls. What pitch screws and motors
(belts/pulley ratio) are you using on the XYZ axis?

Which does exactly the same as my code,
I'm going to guess that low-level I/O error is a general

No. It is a different error. I can't remember the exact wording but I
have seen it before.
The following error message is correct. With steppers you have two
acceleration settings. There is the joint

Something like so:
$fn=$preview?$fn:180;
h = 5.25 ;
r1 = ( 73.6/2.00 ) ;
r2 = ( r1 + 2.6000 ) ;
rotate_extrude(angle=123) {
translate([r1,0]) square([r2-r1,h]);
}

Greetings all you OpenSCAD experts;
I had no trouble making a ring with this code:
h = 5.25 ;
r1 = ( 73.6/2.00 ) ;
r2 = ( r1 + 2.6000 ) ;
difference() {
cylinder( h , r2 , r2 , $fn = 180 , center = true ) ;
cylinder( h , r1 , r1 , $fn = 180 , center = true ) ;
}
But how do I generate

The comment on the link about Ethernet latency is
LinuxCNC is designed to run servos. The stepgens simulate servos and
will throw a following error if they are unable to generate steps at the
commanded rate or acceleration. As Peter says, you probably increase
your stepgen acceleration.

The load part is interesting. I wrote this Lazarus program to calculate force
required based on what was going to be moved and leadscrew pitch etc. It was
never finished. Don't know how accurate it is.
Might be worthwhile to add Step Rate and Max Acceleration conversions so the
