General questions on best method for installing Linuxcnc for software stepping.

OK, in that case you should be able to fix the problem with millkins, as I think you already said?

wiki.linuxcnc.org/cgi-bin/wiki.pl?Contri...y_XY_skew_correction

Have you tried it? What was the result?

Now keep in mind I probably screwed something up but when I finally got the dev tools installed and got the millkins.c to compile linuxcnc would not launch. I modified the .hal file to chancge trivkins to millkins_xyz and added the setp parameters. Linuxcnc still would not launch.
So then I rolled back to 2.7.8. removed millkins_xyx.ko and that got me up and running again.

What error did you get?

Where did you get your millkins from, and how did you install it?

So I tried to follow the method based on this page
wiki.linuxcnc.org/cgi-bin/wiki.pl?Contri...y_XY_skew_correction
I downloaded the latest dev image using the instructions on build bot
I then used

sudo halcompile --install millkins_xyz.c

This appeared to compile without errors but it was fast so I might have missed a prompt.
Then I tried launching linuxcnc it stated a message that it was going to reconfigure my config files to support joints and axies. After it did that linucnc crashed and if i remember correctly the error seemed to be about millikins_xyz not letting the math stepgen and a bunch of other files to open because of an "argument error" when I get home from work I'll try it again and post the entire error log file.
This error did not change when I changed trivkins to millkins_xyz.
Then I copied the millkins_xyz.ko file and saved it so that when I downgraded back to 2.7.8 I could try it out and if I recall correctly the error log read very similarly.

That process was somewhat confused by the fact that you also switched to the new version of LinuxCNC which has a different layout for the HAL and INI files.

You should only need the millkis.c file from that Wiki page, and should have been able to compile and install it with halcompile without any need to get the latest development version of linuxcnc.

if you need the millkins_xyz version, then download that file instead, but follow the instructions for millkins (except for the filename).
