Belts and gearboxes do introduce backlash.

No encoder is exactly precise.

Be aware that vibrations can trigger sensitive switches like those used in most mechanical keyboards.

My Logitech G413 carbon mechanical keyboard turns on my iMac if I bonk the table it rests on.

But it uses romer-g switches.

(And it was scavenged from garbage)

'comp' is listed twice. The first entry is correct:

 

The second is the wrong one.

I need an aluminum clamping table like that!

Where'd you get that anyways?

Looks great!

FUN FACT: most CNC machines are CNC-machined, most 3D-printers are 3D-printed.

Kinda weird, eh?

Since that's a list of hal components, the link is correct
but the description is not.

OK, That's entertaining...

It should be possible to home by using a component that
measures the distance between index's and only arms
the actual index logic by simulating home switch detection
when the correct inter-index distance is measured.

Hello,

I tested the S-curve feature on the following system:
PC: HP with Intel i3 3rd Gen, 2x4GB RAM (latency < 20k)
OS: Debian 12
LinuxCNC: 2.10 pre-release
I created an XYZ mill configuration using StepConf and ran the same G-code with and without tpmod_scurve.
The results can be seen in the attached videos.
Observations:
Without the S-curve, the feed rate remains continuous.
With the S-curve enabled, the feed fluctuates significantly—at times dropping to 1/10 of the programmed feed rate.
It also noticeably increases the overall program execution time (2,5x slower with scurve in this situation).
I tried increasing VECTOR_BUFFER_SIZE to 100, but it didn’t help much. (Just for testing, I also set VECTOR_BUFFER_SIZE = 2, which made the behavior even worse.)
Maximum velocity and acceleration settings are visible in the video (they’re not particularly high, and are the same in both cases).
Question:
Do you think it's possible to achieve a continuous feed rate using the S-curve?

I was able to install it now, thank you!
Will update if it works as planed.

try:

variable int last_Tin = 0;

I acctually name it pos_latch.comp when creating the document.


I've created working functions before but those only used floats.
Follwing File installs no problem...:

Name the file pos_latch.comp, the comp thing makes it go through the preprocessor.

Hey Guys
I'm trying to write a function at the moment but it does'nt accept me using a bit.
Probably jsut missing something small.
I get following Error with following function;

CODE:
pos_latch.c:29:5: error: unknown type name ‘bit’
   29 | bit last_Tin;
        | ^~~
make: *** [/usr/share/linuxcnc/Makefile.modinc:117: pos_latch.o] Error 1


FUNCTION:
component pos_latch;
license "GPL";

pin in float Pin;
pin in bit Tin;
pin out float out;

variable bit last_Tin = FALSE;

function _;

;;

FUNCTION(_) {
    if (Tin && !last_Tin) {
        out = Pin;
    }
    last_Tin = Tin;
}

 

Twincat is a Windows program, a huge one with a learning curve so if you haven't use it before then it's not worthwhile now. It's anyway only an easier way to view data from the drive and it would be some detective work to see why yours doesn't go OP.
Google is your friend, or actually the search on this forum.
I found this forum.linuxcnc.org/ethercat/52997-ethercat-catio-module-help with what seems like a working config.
And you you should definitely do ajust to make sure the master's data about the client is up-to-date.

Not sure Langdons. I'll have to look at the manual.

Made some progress with the control panel today. Machined the panels on the router and welded up the frame. Just need to countersink the panels and tap the rear mount holes. Not shown are the monitor facia and rear panels. Should be off to powder coating next week. I'll start 3d printing the custom keys in the meantime. Pictures below.

Cheers,
