Re: [Emc-users] Acorn CNC
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 bug me but then I've done a project using a Pi3 interfaced with SPI to a PIC32. And many decades ago a grad project with Unix on a PDP-10. But I detest, if that's even a strong enough word, command line operation. And so do most people which is, I believe, why there is such a resistance to Linux. So as the attached screen shot shows, I prefer that approach to a bunch of command line questions and answers until I get the correct G-Code. So I suspect do 99.9% of the computer users. The rest use Linux.

The Mesa 7i95 with Ethernet connection to the PC and a choice of user interfaces with or without touch screen.

So far we haven't exceeded the I/O on either system.Costs are somewhat comparable. However, after that introductory carrot, the price for the Acorn jumps by another $159 for the "Mill Pro" which now lets you use that rotary table and do Rigid tapping. So now the Acorn is well above the price of the LinuxCNC system. We'll ignore the price of the PC for now since both are required (along with motors, belts, pulleys, limit switches etc.). If you go out and buy a laptop it probably comes with Windows 10. Finding an inexpensive laptop with hard wire (verses WiFi) internet connection is getting harder. Not sure about the touch screen side of things. Either laptop or a monitor. So price wise, MESA $295 plus some relays and a power supply so say $400. The Acorn $329+ $159= $488. So Acorn more expensive but turnkey compared to trying to install LinuxCNC on a new piece of hardware, trying to figure out what a HAL and INI file do, which user interface to install and so on...

For that matter cost wise there's also MACH4 with the Ethernet SmoothStepper or a few other similar interfaces. Cost wise also in the $400 range. So why LinuxCNC? John A 7I96S is a much closer match to an Acorn (and has more basic I/O and more expandability) for $149 A 7I95 allows 6 axis of encoder feedback (not something the Acorn can do) Peter Wallace Mesa Electronics ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Acorn CNC
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 provides enough IO support for a good, basic machine (plus it's one of the only mesa cards in stock). The gk41 dual boots easier than any other computer I've installed LinuxCNC on, so you can keep the windows side for whatever sadistic reasons you may have and even a build from scratch deb11/2.9 install is a breeze (if you follow my video, of course ;} ). The stigma of learning Linux is slowly getting chipped away with enhancements to the Linux user experience (I run cinnamon on a few of my computers just because it looks nice). As far as limit and probing IO, there are a bunch of ways to consolidate inputs. For starters, if you are running 2 limits per axis, just wire them in parallel (NO) or series (NC). Same can be done with the tool setter and probe as long as you have a way to circumvent the circuit trigger when the spindle probe is disconnected. Case in point, my tool setter and spindle probe are both NC when connected, but the probe is detachable from the wire, essentially making it NO until it's connected. This makes for an unhappy trigger signal. To fix this, I originally used a spdt switch, then moved to a spdt relay, finally to classicladder logic and two inputs on my motion board. If you want to still use one input, the spdt relay works very well or you can just jumper the probe when not in use. And as far as anything called Mach, 3 is outdated and the last version had a fatal bug that crashed my machine and scrapped way too many parts (which is why I went to Linuxcnc in the first place) and I hear 4 is still not quite right.

Re: [Emc-users] Acorn CNC
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 MACH too. The simple reason is that I ended up buying off EBAY a harmonic drive for my 4th axis. Up until then I had Parallel port and dual boot PC for WIN-XP and LinuxCNC. And I'd even run my mill with the Xylotex Beagle Cape and Machine Kit. But the STMBL AC servo driver has the issue that if there is a voltage bump or the power isn't there yet when enable is switched on it faults which then removes power from everything.Won't go into the details but I could never make MACH3 work well with the scenario. LinuxCNC did. I like the tapping ability. I do have a MODIO from Australia that I could add along with MODBUS messaging but I also have CAN bus running (at least on the Pi4 version of LinuxCNC). So I would never buy an Acorn system. And MACH3 for all it's ease of installation doesn't handle odd things well.Linux has been, how can I say it, difficult. But seriously when you look at the simple ready to go with this card and this IO hardware both MACH4 and Acorn are hard to talk someone out of.

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 unit for almost every budget and type of machine (acorn, oak, all in one dc). Plus, their macro logic is more fanuc-like from what I've seen (includes the dreaded GOTO) The selling point of LinuxCNC is price point and available power, if you're willing to put in the time to learn.

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.

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 kinematics, tool changers, integration with external elements (bar feeders, robots, etc) and the like.
