If there is a problem there then it is a problem of my creation, as I wrote the resolver driver for the 7i49. Resolvers don't have an index, but I have pretended that they do because LinuxCNC is used to seeing index behaviour with encoders. The thing is that LinuxCNC should be used to seeing an enormous step at encoder index during homing, and should know how to ignore it. I use resolvers, homing to index, on my own machine, and there are no issues with f-error during homing. Are you allowing LinuxCNC to control the resolver.N.index-enable pins, or are you doing something clever in HAL? -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
