Hello all,
Mesa 6i25/7i76 combo fitted into an intel i3
It's only the PC sitting in the office, no drivers etc. connected yet.
I made a fresh install.
debian 10
rt-preempt
linuxcnc 2.8 from stable repository
worked great ...
Then I took a config I had, which is a gantry config XYYZ
when I start axis, just press home for each joint
then move X Y and Z
Z moves fine, X and Y move in the wrong direction
if motors are stepper
a quick way is invert one of stepper motor coils
other than that, X when it moves positive, it runs fine, negative it runs a
fraction of a sec and stall's with machine disabled just like a following
error, but no error shows up.
I'm used to see that little boxes on the lower right corner of axis that say's
following error.
Any advice?
also check the settings for the stepgen max velocity and stepgen max
acceletarion they should be 25% greater that max velocity and max
acceleration
```
MAX_VELOCITY = 60.0
MAX_ACCELERATION = 500.0
# The values below should be 25% larger than MAX_VELOCITY
STEPGEN_MAX_VEL = 75.0
STEPGEN_MAX_ACC = 575.0
```
