two independent X at the same time.

i decided to start from more simple thing - XYUV.

i got two problems that i could not solve:
1. pair UV always stops with joint following error. i've read manuals and tried to change parameters that can be responsible for this mistake but failed.
and one thing i noticed that i do not understand: one can't just define AXIS_0, 1, 6 and 7. all of them (XYZABCUV) have to be described, from 0 to 7 explicitly. that makes emc2 to load every even the most simple ngc file for a half of a minute. but in hal file i can define only that axes that are needed (0,1,6,7). so emc uses 8! axes and maybe somewhere there the PC "loses" its ability to count all of them? maybe i use a wrong word (english is not my native).

2. after redesigning the schema one pair of axis (XY) wherever it is switched works fine. but UV never makes even a single step before joint error. but GUI shows that movements occur. is there something that i could miss?

conf files:
unas.ltd.at.tut.by/9.ini
unas.ltd.at.tut.by/9.hal

Axis UV (AXIS_6, AXIS_7) are not mentioned in your hal

the wrong file, i'm not behind the machine. but after 100 times reading manual i made a working configuration.

why did you say that all axes have to be linear? maybe this can affect.
the file is edited now.

why reusing if different pins are used?
i lost it, cannot reproduce it on home PC, but if i just edit ini file to use all that 8 axes, it even at this stage gives joint folowing error.

I assume you got the following errors because the axis are not in the hal file.
It is not enough to have it in the ini file.

i thought about it too after i saw X and Y do not produce following error(FW). everything from Z to V has FW. but... i have U and V in hal file, they are the same as X and Y only with their names, you can see it - i edited abovementioned file.

i edited it several times and reposted - it is actual and working but it always gives FW for U and V for example in g91 f1 g0 x5 y5 u5 v5
unas.ltd.at.tut.by/9.hal
and
unas.ltd.at.tut.by/9.ini

I think the problem is in these lines:and
look carefully at the numbers. stepgen.3 is stepgen number 3, this is ok.
But axis.3 is AXIS_3 and this is axis A !

so I would try:and
Note also:

If you skip axis in the hal file you always have the risk of follower errors.
In axis GUI you always see all axis in the "manual" menu.
If you accidentally select a non-existing axis and hit the +- buttons you have a follower error.
Could be there is a method to remove not used axis from menu, but so far I have not found it.

To avoid the confusing numbering and the risk of follower errors , I always include all axis in hal, which are defined in ini.

EDIT: added lines for enable axes
