I'm going to guess that low-level I/O error is a general
_Following_Error_Joint_2_?
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

The comment on the link ab
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.

OK,this is EXTREMELY bizarre! In open loop, how could

I made another video with the new 3D printed pulley. Much better balanced as I
made the inner hole and outside hub thicker and then bored and turned it to the

could it be that my z-axis is too slow for a certain movement? i think the

happen on g0 commands after about 40mm of movement. if there is a time
constraint, the software could trap into a timeout and answer with a

i'm new to this...

new to linux
since i've almost finished a conversion of a desktop micro mill, i tried
some of the example g-code files installed from the bdi.
i use brushed dc motors together with whale2 drivers in

so far so good - but sometimes
When emc shows the following error on joint message for a
stepdirection system, that means the system is misconfigured. There
are two main causes for this error:
Cause 1: Insufficient headroom for acceleration and/or velocity.
Emc2 defines velocity and acceleration limits in both the trajectory
