Is a parport fast enough?

Is parport fast? nope. Is it enough? Certainly is!! Some of the parts coming out of my Lcnc parport 4ax mill are beyond words - if measured for what it is.

No comments on the ChatGPT bit. Apart from being glad I won't be here in 20~50 years to witness a chronically suffering civilization whom had their natural neural plasticity annihilated for incentives by BigTech. Geez imagine the keyboard zombies coming up!!!

As far as driving the A-D chips from that  parallel port,
That should be possible even using the normal hal_parport driver
and a simple component with a basethread driven state machine.

(ChatGPT will not help here, it's just a time sink)

The main issue would be the encoder as the encoder resolution*speed
will limit the maximum speed significantly with parallel port sampling speeds.

Hey great! Thanks for the real responses! I can appreciate the hate you guys may have for ChatGPT. I get it! I use it all the time for programming simple micrcontrollers. I knew that it wasn't quite correct. I put it there just as a thought. I didnt think there would be such an up-roar! lol I am not trying to be lazy. I just got lost in code. My brain says NO! I can build almost anything, except software!

That being said! I am a hobby CNC guy. I love these machines. I mostly build speaker boxes and I make random parts for my friends, typically for things that are obsoleted and you can't find parts. (Metal or wood) I have a Makino Lablonde FNC-106. It is a 20,000 pound absolute dream of a machine from 1988. It is as accurate as anything built currently (actually more accurate than some). It is a beauty! I also have a 1996 Morbidelli Author 502. I have replaced the NC with Mach and a Galil Motion Control. I has been good but recently, a rat chewed on some wires and fried the control card. I am playing with some ideas on replacing it on a budget. I just vbought a truck so I really dont have much to spare.

I do however have TONS of different gear around here to repurpose. I have several options. one was the parport idea. It was only a thought. Now the other thought that I have is an FPGA. I have several different FPGA boards. I am, again, just having issues with the software part of them. I have included a couple of photos of them. I think I can make the colorlight board work... With the DAC as well! I am just having difficulties. The other board that is by itself.... I think would also be a real good candidate. Anyone know much about Reverse Enginering?

One of those should already work for the LED driver boards you have.

The Litehm2 project is for the Spartan 6 FPGA so only the RV901T is suitable.

The Litexcnc project is for the Lattice based boards.

There's also Ollie's Linuxcnc rio project, and just maybe if you ask him nicely he may be able to work his magic for your DAC. Don't know if he supports analogue servos, but might be worth hittng him up.
