Hi
I want somebody help
I think now my CNC problem seem this topic.
My CNC XYZ and Y correct linear move
my X axis table on Y-axis base it's Skewed angle .
forum.linuxcnc.org/49-basic-configuratio...s-xyz?start=0#280714
I D/L this file from MR.Aciera

I open terminal and compile file

asis@192:~/Downloads/skewkins$ sudo halcompile --install skewkins.comp
[sudo] password for asis:
Compiling realtime skewkins.c
Linking skewkins.so
cp skewkins.so /usr/lib/linuxcnc/modules/
asis@192:~/Downloads/skewkins$

I open hal

#loadrt [KINS]KINEMATICS
loadrt skewkins
setp skewkins.skew 0.01

I open ini

[KINS]
JOINTS = 4
KINEMATICS = skewkins

this problem when run linuxcnc

Note: Using POSIX realtime
./217-4x.hal:7: parameter or pin 'skewkins.skew' not found

that kinematic does not have a pin called 'skewkins.skew'. Try 'skewkins.skew-y':

It's a ratio. units of skew in Y per unit of travel in X. If you set 'skew-y' to 0.1 then moving the y-axis in the positive direction will have the x-axis move 0.1 units in the negative direction for every unit of y-travel.

j [0] = pos->tran.x - pos->tran.y*(*(haldata->skew_y)) - pos->tran.z*(*(haldata->skew_xz));
j [1] = pos->tran.y - pos->tran.z*(*(haldata->skew_yz));
j [2] = pos->tran.z;
