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...:
component Test;
license "GPL";

pin in float in;
pin out float out1;
pin out bit out2;

function _ nofp;

;;

FUNCTION(_) {
out1 = in * 3;
if (out1 == 3.0)
   { out2 = true; }
else
   { out2 = false; }
}

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 a
ethercat rescan
just 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,

I have the "C" version of the scale.

From what i understand it should be possible to calculate the absolute position on the scale by traversing past two reference marks. See picture 4 on page 9.

Yes, that is clearly a mistake.
Should probably be 'halcompile' and link to this man page:

I’ve bought a hydraulic chuck closer for the lathe chuck, but in order to mount it onto the spindle shaft, I need to cut a thread on the spindle. After that, I’ll add an additional gear on the spindle, which will be connected by a belt to a second servo motor with a 1:2 gear ratio. The motor will be mounted on top of the spindle housing

Did anyone have any luck configuring one of these? I followed the links on the first page to get the slave information, but mine seems to be stubbornly returning to PREOP E. here's my slave information so far:

lcec_configgen resulted in a fairly similar output to what I had already configured.

From that additional post you linked, they found the config files for what seems to be a very similar IO board/device to mine, but the ESI (xml file) seems to be rather... convoluted?

I have attached it, but unfortunately didnt' reveal enough information for me to figure out anything new - and thus i'm still stuck on PREOP E. 

I'm also not sure how TwinCAT is supposed to work - but i'll keep playing with that and hopefully have some luck. maybe you could suggest which package I need? 

Here's my whole ethercat-conf.xml as a side note, in case you see something wrong with it:

exactly, the servo is configured as an analog output and can be controlled with values from -100 (open) to +100(closed).
net sig_motion_analog-out-00 <= motion.analog-out-00
net sig_motion_analog-out-00 => rio.gripper.position

This doesn't seem right.  Oddly, if you click on "comp", the description on the page is that of a comparator.

I think you need to specify a home position that's some distance from the home/limit switch location

Issue getting XYYZ gantry to home (using 7i92t with 7i76u)

Category: Basic Configuration

Hi All

Thank you for your feedback, greatly appreciated :)
The Y gantry completes the four step process now, well ... very nearly.
I think my problem was here
[AXIS_Y]
[JOINT_1]
has negative values
HOME_SEARCH_VEL = -10.000000
HOME_LATCH_VEL = -5.000000
(and joint 2 had the same negative values).
[JOINT_2]
I changed the signs to both positive
HOME_SEARCH_VEL = 10.000000
HOME_LATCH_VEL = 5.000000
After that change, the Y-axis homed in the four step way.
I don't understand why,  maybe gantry motors that face one another need opposite signs, I have no idea.
I have attached three screen photos with halshow
first - just switched on power supplies, and launched Linuxcnc.
second - after clicked estop, and clicked power.
third - end state after all thee axis homing has completed.
Physically the Y gantry does the correct four step movement.
However, Linuxcnc errors out right at the very end, indicating joint2 on limit switch error.
The  y-is-homed is red , while x-is-homed, y2-is-homed and z-is-homed are all yellow.
These are the cheap 2mm proximity sensors , tommylight said earlier that these are best avoided.
I will buy better quality ones.
If anyone knows why that sign change worked please let me know
