Hi Phil,
Kinda what I said too. Cost wise I don't think there's a difference. It comes
down to mentality. One user stated he went Acorn because the parent company
runs real CNC. Whatever that means.
I still think the biggest obstacle to LinuxCNC is the first 5 letters of the
name. Doesn’t

Hi Ralph,
The reason I ask is the replies are often like yours
My hard and fast answer for why LinuxCNC would, again, come down to cost. A
coofun GK41 mini pc has more than enough gusto to drive a Mesa board and if
you have the right link on Amazon, will run you $169 before the United
States of Legalized Extortion take their cut. A Mesa 7i96S is $149 and
Actually Phil you and Sam have both answered the question. I'm trying to avoid
the preaching to the choir answers because then it's a Ford verse Chevy
argument and they both have 4 wheels and a steering wheel.
I could not have gotten my system up and running with Acorn and I had to bail
on
Hi Ralph,
The reason I ask is the replies are often like yours with an incorrect
assessment of features.

I thought path pilot started using a Linuxcnc fork from machine kit?
Centroid is appealing to new users because of a few reasons: ease of setup
(no hal), conversational (although not great) and a unified ecosystem of
hardware and software, with the ability to find a plug and play centroid

I have almost stopped evangelizing linuxcnc... (almost) People are going
to use what they are going to use. I just try to put out how cool and
flexible linuxcnc is..
The acon is really one of the few hobby grade controllers that can thread
and rigid tap. Plus you have the history of the

What kind of machine does the potential Acorn buyer plan to control?
Most of these newer controls are aimed at vanilla 3-axis cartesian
machines. They generate step/dir pulses, and have three home inputs,
and not a lot else. LinuxCNC really shines when you have more complex
I/O needs, unusual

OK tested LCNC 2.8 with preempt_rt and the encoder signals make it to
the GUI using a preempt_rt kernel vs RTAI!
NO signal 8 core dump \0/
So it looks like an RTAI bug with 2.8 at least about the encoders
signals to spindle RPM GUI in Axis.
Will go back and trace why preempt_rt has issues
