Re: [Emc-developers] Hardware testing for improved spindle tracking jitter (issue 164)

I'm glad that it's running well now. It would be cool to find a machine that's borderline and see if the patch makes it run smoother. On Sun, Sep 25, 2016, 8:00 PM andy pugh wrote: > On 26 September 2016 at 00:46, Robert Ellenberg wrote: > > > Thanks for giving it a run! It is hard to tell if i

Hi Kirk, Thanks for giving it a run! It is hard to tell if it's an improvement, but it does look like it's tracking smoothly, It would likely help to compare the same run without the patch to see if the velocity jitters more. On Sun, Sep 25, 2016 at 5:41 PM Kirk Wallace wrote: > On 09/25/2016 1

When this gets pushed just tell me what and how it works and I'll update the docs. JT On 9/23/2016 1:50 PM, tero.kaarl...@eka-sorvaus.fi wrote: > Hi, > > It seems I was wrong. DISABLE_SPEED_OVERRIDE and DISABLE_FEED_HOLD do > work. Using halmeter for pin motion.spindle-speed-out confirmed c

Thanks to you both! I just pushed the branch of the same name to the official repo. Unfortunately, it looks like the buildbot queue has stalled on this build: http://buildbot.linuxcnc.org/buildbot/builders/.checkin/builds/4528 Once it gets through the queue, though, my branch should have a bu

[Emc-developers] Buildbot stalled

It looks like the buildbot is stuck on this build: http://buildbot.linuxcnc.org/buildbot/builders/.checkin/builds/4528 It's been running a test for 35 hours, and other builds queued up behind it haven't started. -Rob ---

[Emc-developers] Hardware testing for improved spindle tracking jitter (issue 164)

Hi All, Recently, I found a way to reduce the acceleration / velocity jitter during threading and tapping motions (see this issue on github and the feature/spindle-sync-jiiter-fix branch
