Linux Mint with RTAI

Just a brief not to follow up on my last transmissions. I installed Linuxcnc 2.7.3 on Linux Mint 17.2 Mate and 17.3 mate on 32 bit machines and they work great after I commented out Cam View, as suggested. I then installed Linux Mint 17.3 on my 64 bit machine and then installed Linuxcnc 2.7.3 with the 64 bit kernel. It is also working great and my machine of choice at this time. Thanks again to all those that made suggestions that lead to my success in this venture.

Followed a different install method, working now.

Hi,

Having some problems with this.

Here's the output from the terminal.

tk8.6-dev is the part that is causing the issue.

I have no idea what to do about the "size mismatch" error.

Any ideas?

Thanks!

I do believe Debian uses TCL and TK ver 8.5 where Mint and Ubuntu use 8.5 or 8.6. I have not messed with this in a while do not have time at this moment to check it out. You are welcome to try and fix then post here and I will update script later when I get a chance to see your post.

Good luck
Tim March :dry:

as tim says use tcl & tk 8.5 .
try and use debian ftp rather than obscure ones may help too

Thanks!

It looks like TJ made some changes to the .iso. I wasn't able to download them the other day, I tried again a couple days ago and saw that he had re-uploaded them.

The new iso worked fine with LMDE 2 Betsy.

So far so good, the new (to me) computer will be here Tuesday, I'll see how it runs.

Regards,

Matt

I am having the problem of axis not running and the error message that was discussed back on the first 2 pages of this thread.

I used the install procedure from Big John from his mesaus website in the download section. Apparently some newer versions are out since that doc so I installed them (mint 17.3, linuxcnc 2.7.4).

I believe I followed the instructions correctly but have the exact problem of axis not starting and the error message as in the first couple pages of this thread. (task: 513 cycles, min=0.000018, max=0.008041, avg=0.002026, 0 latency excursions (> 10x expected cycle time of 0.001000s)

I have read the entire thread but cannot figure out what might be the cause / cure for axis not starting. Naturally I do not want to do a complete reinstall with a different method if there is a way to "fix" the current install. I did not see any bottom line cause for the axis not running problem.

Any help much appreciated !
