The newest version of Machinekit separates "emc" from hal, and permits their hal to compile with standard Linuxcnc 2.8 if I recall correctly. Their focus has always been on the hal end of things rather than gui's and cnc machining.
I can't find the email post that explained this, and the machinekit documentation is rather sparse, so how one actually installs things with current LinuxCNC high level code and Machinekit hal code, I couldn't tell you. -- Ralph ________________________________________ From: Rob C [rclandro...@gmail.com] Sent: Wednesday, January 5, 2022 10:53 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] Tormach writing open sorce ROS2/Machiekit/LCNC bridge. CAUTION: This email originated from outside the Walla Walla University email system. I was also confused by machine kit reference from tormach. I thought tormach was based on linuxcnc and not the machine kit branch/fork although I guess if Tormach are running a 2.7 linuxcnc version I guess you could say they have their own branch/fork I would have thought that since the change to python 3 with linuxcnc that will be quite a divergent change to linuxcnc that will make it difficult to integrate any items pushed back to 2.7 On Wed, 5 Jan 2022, 18:38 John Dammeyer, <jo...@autoartisans.com> wrote: > > From: Chris Albertson [mailto:albertson.ch...@gmail.com] > > > > On Wed, Jan 5, 2022 at 3:29 AM Gregg Eshelman via Emc-users < > > emc-users@lists.sourceforge.net> wrote: > > > > > That repeatability is plenty good enough to drop work into an automatic > > > holding fixture (which does the final precision positioning) then pick > the > > > pieces out for transfer to another manufacturing stage or into a box. > > > > > > > > As it turns out, for all the really hard tasks, +/- a quarter-inch > (0.25") > > is accurate enough.
