Introduction along with some questions regarding LinuxCNC

Hi everyone, I am Arijit from India. I do have a small 7x mini lathe for which I intend to install ballscrews and steppers for each axis and try to CNC it. I make some small plastic parts which are quite simple but has threading on each of them. I was looking up on internet regarding CNC controllers till I found Centroid acorn and LinuxCNC which are quite robust and has a good community behind them. I looked up on some videos regarding Centroid acorn, they seem to me almost plug and play but comes at a hefty price. Whereas LinuxCNC with a Mesa board is almost half the cost of that of Acorn but is expandable.

Now, coming to myself, this is my first CNC conversion. I dont have any CNC experience or associated electronics. Seeing Acorn, I am pretty sure I will be able to hook it up according to the schematics and videos that are up on youtube and also the software is pretty straightforward which is pretty easy for a newbie like me. I was looking into LinuxCNC and mesa board schematics as well for the last few days. It feels intimidating when it comes to things like 'HAL' and similar stuffs where I have to troubleshoot myself if things like the encoder dont work. Its not like that I am not willing to learn but it feels there is a hell lot to know. Does LinuxCNC have a steep learning curve or am I overthinking too much?

There's simply no substitute to Linuxcnc in the customizable-ANY-hardware arena - second to none - hands down - five stars. 
However, and to be honest, it is not tailored for beginners at all. That's where it fails dramatically. 
You are not overthinking this; a significant amount of knowledge of HAL and Python will eventually be required.

I'm entering my 4th month of learning, research, config, tweaking this & that, and yet made a single part - just tests.
Lots of fun though. Zero complaints and no regrets.
Good luck

Tempting to share how much of a struggle it was just to get the spindle to spin let alone pid modbus lincurve cw/ccw m3/m4 swapped offset bugs screw comp what not mpg probe tool setter debouncing... ... ... the hal & python debug and rebug list is just f n endless /kb_on_fire

Lcnc is for geeks (which I am luckily), and for dudes/dettes who dream and think like electrical engineers for some weird reason. Not for machinists and even less for beginners. There, some constructive criticism!!

Then to the control hardware and enclosure; motor induction vs volts, dedicated current for that, shielded forthis, twistedpair forthat, ground for here, separate ground for that... oh good god. Haven't yet ranted on the x86 and network interface hardware randomness and latency tweaks...

For beginners, sure. Worldsss and Universesss distant rather. Lots of work for the X and Z to move. Be warned lol

3min for stepping via parport. Sure, I'll give you this, that's very true. Now go hook up a spindle motor and tune it beginner - see you next week, be mindful of that coffee abuse.

I'd hate for anyone to take it wrong or misunderstand; I build, destroy & rebuild ever since I was able to lift a hammer with one hand (4 years old?). Retrofitting dumb and static machine-tools and empowering them with Linuxcnc is and forever will be ranking top of the best & most fun built I've carried out. Invaluable knowledge acquired - No Regrets. Thanks to YOU all for that btw.

I'm just saying. It is so NOT for beginners and I'll stick with that. Personally, that HAL thingy drives me absolutely nuts. Hated it. Traumatized For Life in fact.

(ps thanks for listening everyone, feeling so much better now lool)
