Gentlemen, If it hasn't been posted yet the solution to my problem (KINDLY pointed out by Chris Radek) was I had left out the '=' sign in the command 'COMP_FILE = joint0.cmp'. Thank you very much Chris. If I wasn't so relieved I would be embarrassed beyond belief. As it is, I am a happy ca

Gentlemen, Upon further investigation I am unable to use the lead screw compensation files we collected. I adjusted the scale to minimize the compensation magnitude. This allowed me to machine the test article to a 'pretty close' configuration. I have since discovered the lead screw comp is no

Alex, Thanks for the response. John, Now I understand the comment about patience. I had submitted a post, received a bounced notice and reposted. Then I see the first post was there also. Sorry. Just to clarify for me. The way I see it the compensation is interpolated between points as it looks

I hope to get cheaper rolled lead screws and use lead screw compensation to get ground screw performance on my lathe project, so I will be watching this thread. Just in case it might help, there is below an excerpt from: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Kinematics On Sat, 2007-03-10 a

Gentlemen, I am nearing completion of the installation of EMC2 on a small three axis mill. I will shortly need to implement lead screw compensation. I have been unable to find much in reference to this. Where would I find out how to implement this? thanks Stuart --
